Currently, we need virIsDevMapperDevice() when we build libvirt with
disk or mpath storage drivers.  So we should check device-mapper-devel
when we build with disk storage driver but without mpath storage
driver.

Two regressions:
Commit df1011ca broke builds for systems that lack devmapper
(non-Linux, as well as Linux with ./autogen.sh --without-libvirtd
and without the libraries present).
Commit ce6fd650 broke cross-compilation, due to a gnulib bug.

* .gnulib: Update to latest, for cross-compilation fix.
* src/util/util.c (virIsDevMapperDevice): Provide stub for
platforms not using storage driver.
* configure.ac (devmapper): Arrange to define HAVE_LIBDEVMAPPER_H.
devmapper issue reported by Wen Congyang.

* configure.ac (gl_ASSERT_NO_GNULIB_POSIXCHECK): Use to reduce
time spent in configure.

The name convention of device mapper disk is different, and 'parted'
can't be used to delete a device mapper disk partition. e.g.

Name                 Path
-----------------------------------------
3600a0b80005ad1d7000093604cae912fp1 /dev/mapper/3600a0b80005ad1d7000093604cae912fp1

Error: Expecting a partition number.

This patch introduces 'dmsetup' to fix it.

Changes:
  - New function "virIsDevMapperDevice" in "src/utils/utils.c"
  - remove "is_dm_device" in "src/storage/parthelper.c", use
    "virIsDevMapperDevice" instead.
  - Requires "device-mapper" for 'with-storage-disk" in "libvirt.spec.in"
  - Check "dmsetup" in 'configure.ac' for "with-storage-disk"
  - Changes on "src/Makefile.am" to link against libdevmapper
  - New entry for "virIsDevMapperDevice" in "src/libvirt_private.syms"

Changes from v1 to v3:
  - s/virIsDeviceMapperDevice/virIsDevMapperDevice/g
  - replace "virRun" with "virCommand"
  - sort the list of util functions in "libvirt_private.syms"
  - ATTRIBUTE_NONNULL(1) for virIsDevMapperDevice declaration.

Make with_packager and with_packager_version default to "no". This way
--without-packager-version (as shorthand for --with-packager(-version)=no)
works correctly too.

Prior to this patch libvirt outputs a line like this when
--with-packager(-version) was not specified

# ./daemon/libvirtd
14:11:15.018: 31796: info : libvirt version: 0.8.8, package:  ()

Now the unspecified parts are correctly omitted.

Reported by Osier Yang.

The logging functions are enhanced so that immediately prior to
the first log message being printed to any output channel, the
libvirt package version will be printed.

eg

 $ LIBVIRT_DEBUG=1 virsh
 18:13:28.013: 17536: info : libvirt version: 0.8.7
 18:13:28.013: 17536: debug : virInitialize:361 : register drivers
 ...

The 'configure' script gains two new arguments which can be
used as

   --with-packager="Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10"
   --with-packager-version="1.fc14"

to allow distros to append a custom string with package specific
data.

The RPM specfile is modified so that it appends the RPM version,
the build host, the build date and the packager name.

eg

 $ LIBVIRT_DEBUG=1 virsh
 18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10)
 18:14:52.086: 17551: debug : virInitialize:361 : register drivers

Thus when distro packagers receive bug reports they can clearly
see what version was in use, even if the bug reporter mistakenly
or intentionally lies about version/builds

* src/util/logging.c: Output version data prior to first log message
* libvirt.spec.in: Include RPM release, date, hostname & packager
* configure.ac: Add --with-packager & --with-packager-version args

* configure.ac (PARTED_FOUND): Issue configure error if
--with-storage-disk=yes but no parted is found.

* .gnulib: Update to latest, for sigpipe and sigaction modules.
* bootstrap.conf (gnulib_modules): Add siaction, sigpipe, strerror_r.
* tools/virsh.c (vshSetupSignals) [!SIGPIPE]: Delete, now that
gnulib guarantees it.
(SA_SIGINFO): Define for mingw fallback.
* src/util/virterror.c (virStrerror): Simplify, now that gnulib
guarantees the POSIX interface.
* configure.ac (AC_CHECK_FUNCS_ONCE): Drop redundant check.
(AM_PROG_CC_STDC): Move earlier, to keep autoconf happy.

and keep it enabled by default. This allows downstreams to turn it off
via:

./configure --disable-maintainer-mode

as discussed in

https://www.redhat.com/archives/virt-tools-list/2010-October/msg00049.html

* configure.ac libvirt.spec.in docs/news.html.in: bump version and add
  documentation
* po/*po*: regenerate po and pot files

virSetUIDGID() sets both the real and effective group and user of the
process, and additionally calls initgroups() to assure that the
process joins all the auxiliary groups that the given uid is a member
of.

Running an instance of the router advertisement daemon (radvd) allows
guests using the virtual network to automatically acquire an IPv6
address and default route. Note that acquiring an address only works
for networks with a prefix length of exactly 64 - radvd is still run
in other circumstances, and still advertises routes, but autoconf will
not work because it requires exactly 64 bits of address info from the
network prefix.

This patch avoids a race condition with the pidfile by manually
daemonizing radvd rather than allowing it to daemonize itself, then
creating our own pidfile (in addition to radvd's own file, which is
unnecessary, but there is no way to tell radvd to not create it). This
is accomplished by exec'ing it with "--debug 1" in the commandline,
and using virCommand's features to fork, create a pidfile, and detach
from the newly forked process.

All of the iptables functions eventually call down to a single
bottom-level function, and fortunately, ip6tables syntax (for all the
args that we use) is identical to iptables format (except the
addresses), so all we need to do is:

1) Get an address family down to the lowest level function in each
   case, either implied through an address, or explicitly when no
   address is in the parameter list, and

2) At the lowest level, just decide whether to call "iptables" or
   "ip6tables" based on the family.

The location of the ip6tables binary is determined at build time by
autoconf. If a particular target system happens to not have ip6tables
installed, any attempts to run it will generate an error, but that
won't happen unless someone tries to define an IPv6 address for a
network. This is identical behavior to IPv4 addresses and iptables.

brSetInetAddress can only set a single IP address on the bridge, and
uses a method (ioctl(SIOCSETIFADDR)) that only works for IPv4. Replace
it and brSetInetNetmask with a single function that uses the external
"ip addr add" command to add an address/prefix to the interface - this
supports IPv6, and allows adding multiple addresses to the interface.

Although it isn't currently used in the code, we also add a
brDelInetAddress for completeness' sake.

Also, while we're modifying bridge.c, we change brSetForwardDelay and
brSetEnableSTP to use the new virCommand API rather than the
deprecated virRun, and also log an error message in bridge_driver.c if
either of those fail (previously the failure would be completely
silent).

When I run configure, I receive some syntax error.

Now the VMware driver doesn't depend on the ESX driver anymore.

Add a WITH_VMX option that depends on WITH_ESX and WITH_VMWARE.
Also add a libvirt_vmx.syms file.

Move some escaping functions from esx_util.c to vmx.c.

Adapt the test suite, ESX and VMware driver to the new code layout.

* configure.ac (dlopen): Cygwin dlopen is in libc; avoid spurious
failure.
(XDR_CFLAGS): Define when needed.
* src/Makefile.am (libvirt_driver_remote_la_CFLAGS): Use it.

* configure.ac (with_selinux): Check for <selinux/label.h>.
* src/security/security_selinux.c (getContext): New function.
(SELinuxRestoreSecurityFileLabel): Use it to restore compilation
when using older libselinux.

Autoconf 2.59 doesn't define ${localedir}, so libvirt was failing
to compile due to a missing LOCALEDIR until today's configmake fix.

* .gnulib: Update to latest for configmake fix.
* configure.ac (libpcap): Avoid AS_CASE.

Don't require dlopen, but link to ole32 and oleaut32 on Windows.

Don't expose g_pVBoxFuncs anymore. It was only used to get the
version of the API. Make VBoxCGlueInit return the version instead.
This simplifies the implementation of the MSCOM glue layer.

Get the VirtualBox version from the registry.

Add a dummy implementation of the nsIEventQueue to the MSCOM glue
as there seems to be no direct equivalent with MSCOM. It might be
implemented using the normal window message loop. This requires
additional investigation.

* tests/Makefile.am (EXTRA_DIST): Sort, and add directories.
(SUBDIRS): Drop automake recursion into subdirs.
* tests/commanddata/Makefile.am: Delete.
* tests/confdata/Makefile.am: Likewise.
* tests/sexpr2xmldata/Makefile.am: Likewise.
* tests/xencapsdata/Makefile.am: Likewise.
* tests/xmconfigdata/Makefile.am: Likewise.
* tests/xml2sexprdata/Makefile.am: Likewise.

Without this fix, ./configure --with-libpcap will cause --with-libpcap=yes
to be implicitly passed down, which cause yes/bin/pcap-config to be
searched for rather than /usr/bin/pcap-config.

Also output pcap: no when pcap is not found or disabled.

* tests/Makefile.am (SUBDIRS): Add commanddata.
* tests/commandtest.c (checkoutput): Delete correct file.
(test4): Delete pid file.
(mymain): Delete unused variable.
* tests/commanddata/Makefile.am: New file.
* configure.ac (AC_OUTPUT): Build new makefile.

This fixes a misleading error message saying the libnl package
needs to be installed, when it's really the libnl-devel package
needing to be installed.

- configure.ac libvirt.spec.in: bump version, add a missing systemtap
  build requirement
- docs/news.html.in: add informations about the release
- po/*: updated Polish and Dutch localizations, and regenerated
- tests/qemuxml2argvtest.c: Fix build problem

To allow messages from different threads to be untangled,
include an integer thread identifier in log messages.

* src/util/logging.c: Include thread ID
* src/util/threads.h, src/util/threads.h, src/util/threads-pthread.c:
  Add new virThreadSelfID() function
* configure.ac: Check for sys/syscall.h

This is the case on FreeBSD.

This also fixes configure problems on FreeBSD, as test doesn't
understand '==' there.

To avoid the need for duplicating implementations of virStream
drivers, provide a generic implementation that can handle any
FD based stream. This code is copied from the existing impl
in the QEMU driver, with the locking moved into the stream
impl, and addition of a read callback

The FD stream code will refuse to operate on regular files or
block devices, since those can't report EAGAIN properly when
they would block on I/O

* include/libvirt/virterror.h, include/libvirt/virterror.h: Add
  VIR_FROM_STREAM error domain
* src/qemu/qemu_driver.c: Remove code obsoleted by the new
  generic streams driver.
* src/fdstream.h, src/fdstream.c, src/fdstream.c,
  src/libvirt_private.syms: Generic reusable FD based streams

Suggested by danpb, as it's not up-to-date anymore and
lacks many functions that were added to libvirtd.

* configure.ac libvirt.spec.in: new version
* docs/news.html.in: update news page and improve format
* po/*.po*: Update po again

This partly reverts df90ca76.

Don't disable the VirtualBox driver when configure can't find
VBoxXPCOMC.so, rely on detection at runtime again instead.

Keep --with-vbox=/path/to/virtualbox intact, added to for:
https://bugzilla.redhat.com/show_bug.cgi?id=609185

Detection order for VBoxXPCOMC.so:

1. VBOX_APP_HOME environment variable
2. configure provided location
3. hardcoded list of known locations
4. dynamic linker search path

Also cleanup the glue code and improve error reporting.

A missing shell was noisy, and the use of command to decipher a
shell's absolute path requires "" rather than ''.

* configure.ac (lv_cv_wrapper_shell): Fix logic errors if candidate
shell is not available.
* .gitignore: Ignore file created when /bin/sh is old dash.
Reported by Matthias Bolte.

Older dash mistakenly truncates regular files when using <> redirection;
this kills our use of double dd to reduce storage overhead when
saving qemu images.  But qemu insists on running a command through
/bin/sh, so we work around it by having qemu run $sh -c 'real command'
when we have a replacement $sh in mind.

* configure.ac (VIR_WRAPPER_SHELL): Define to a replacement shell,
if /bin/sh is broken on <> redirection.
* src/qemu/qemu_monitor.h (VIR_WRAPPER_SHELL_PREFIX)
(VIR_WRAPPER_SHELL_SUFFIX): New macros.
* src/qemu/qemu_monitor_text.c (qemuMonitorTextMigrateToFile): Use
them.
* src/qemu/qemu_monitor_json.c (qemuMonitorJSONMigrateToFile):
Likewise.

The default location for the XML catalog file, /etc/xml/catalog,
used when validating the generated html docs, isn't correct for
MacOS X.

This commit adds an option to the configure script, allowing the
default to be overridden:

  --with-xml-catalog-file=/path/to/xml/catalog/file

It is useful to know where the client is connecting from,
so include the socket address in probe data.

* daemon/libvirtd.h: Use virSocketAddr for storing client
  address and keep printable address handy for logging
* daemon/libvirtd.c: Include socket address in client
  connect/disconnect probes
* daemon/probes.d: Add socket address to probes
* examples/systemtap/client.stp: Print socket address
* src/util/network.h: Add sockaddr_un to virSocketAddr union

Adds initial support for dtrace static probes in libvirtd
daemon, assuming use of systemtap dtrace compat shim on
Linux. The probes are inserted for network client connect,
disconnect, TLS handshake states and authentication protocol
states.

This can be tested by running the xample program and then
attempting to connect with any libvirt client (virsh,
virt-manager, etc).

 # stap examples/systemtap/client.stp
  Client fd=44 connected readonly=0
  Client fd=44 auth polkit deny pid:24997,uid:500
  Client fd=44 disconnected
  Client fd=46 connected readonly=1
  Client fd=46 auth sasl allow test
  Client fd=46 disconnected

The libvirtd.stp file should also really not be required,
since it is duplicated info that is already available in
the main probes.d definition file. A script to autogenerate
the .stp file is needed, either in libvirtd tree, or better
as part of systemtap itself.
