Add a helper function virBhyveGetDomainTotalCpuStats() to
obtain process CPU time using kvm (kernel memory interface)
and use it to set cpuTime field of the virDomainInfo struct in
bhyveDomainGetInfo().

This commit adds a new example to illustrate peer to
peer domain migration with virDomainMigrateToURI.

We don't support building libvirtd on Win32 since we lack the
fork/exec feature needed for the stateful drivers. Disable this
by default, so users can just do 'mingw32-configure' with no
special args required.

This uses the dbus api of systemd to check the power management
capabilities of the node.

The configure definition previously always defined the GLUSTER_CLI macro
and thus the code needing it wasn't compiled out if the tool wasn't
accessible.

https://bugzilla.redhat.com/show_bug.cgi?id=1072714

Use the "gluster" command line tool to retrieve information about remote
volumes on a gluster server to allow storage pool source lookup.

Unfortunately gluster doesn't provide a management library so that we
could use that directly, instead the RPC calls are hardcoded in the
command line tool.

Commit 5e1d5dde moved the functions using isciadm to util/viriscsi.c,
but ISCSIADM was only defined when the iscsi backend was compiled in.

Define it unconditionally to fix the build (and allow testing
of viriscsi.c) even if iscsi backend is disabled.

configure check for character devices lock path calls
AC_DEFINE_UNQUOTED for VIR_CHRDEV_LOCK_FILE_PATH even if
$with_chrdev_lock_files = "no".

So the locking code in conf/virchrdev.c:

 #ifdef VIR_CHRDEV_LOCK_FILE_PATH

is compiled in even if it shouldn't, because VIR_CHRDEV_LOCK_FILE_PATH
is defined as "no", so it tries to create lock files with strange
lock path like 'no/LCK..'.

Fix that by calling AC_DEFINE_UNQUOTED only if $with_chrdev_lock_files
is not 'no'.

Systemd does not forget about the cases, where client service needs to
wait for daemon service to initialize and start accepting new clients.
Setting a dependency in client is not enough as systemd doesn't know
when the daemon has initialized itself and started accepting new
clients. However, it offers a mechanism to solve this. The daemon needs
to call a special systemd function by which the daemon tells "I'm ready
to accept new clients". This is exactly what we need with
libvirtd-guests (client) and libvirtd (daemon). So now, with this
change, libvirt-guests.service is invoked not any sooner than
libvirtd.service calls the systemd notify function.

The previous OOM testing support would re-run the entire "main"
method each iteration, failing a different malloc each time.
When a test suite has 'n' allocations, the number of repeats
requires is  (n * (n + 1) ) / 2.  This gets very large, very
quickly.

This new OOM testing support instead integrates at the
virtTestRun level, so each individual test case gets repeated,
instead of the entire test suite. This means the values of
'n' are orders of magnitude smaller.

The simple usage is

   $ VIR_TEST_OOM=1 ./qemuxml2argvtest
   ...
   29) QEMU XML-2-ARGV clock-utc                                         ... OK
       Test OOM for nalloc=36 .................................... OK
   30) QEMU XML-2-ARGV clock-localtime                                   ... OK
       Test OOM for nalloc=36 .................................... OK
   31) QEMU XML-2-ARGV clock-france                                      ... OK
       Test OOM for nalloc=38 ...................................... OK
   ...

the second lines reports how many mallocs have to be failed, and thus
how many repeats of the test will be run.

If it crashes, then running under valgrind will often show the problem

  $ VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When debugging problems it is also helpful to select an individual
test case

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1 ../run valgrind ./qemuxml2argvtest

When things get really tricky, it is possible to request that just
specific allocs are failed. eg to fail allocs 5 -> 12, use

  $ VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-12 ../run valgrind ./qemuxml2argvtest

In the worse case, you might want to know the stack trace of the
alloc which was failed then VIR_TEST_OOM_TRACE can be set. If it
is set to 1 then it will only print if it thinks a mistake happened.
This is often not reliable, so setting it to 2 will make it print
the stack trace for every alloc that is failed.

  $ VIR_TEST_OOM_TRACE=2 VIR_TEST_RANGE=30 VIR_TEST_OOM=1:5-5 ../run valgrind ./qemuxml2argvtest
  30) QEMU XML-2-ARGV clock-localtime                                   ... OK

At this point it has a limited functionality and is highly
experimental. Supported domain operations are:

  * define
  * start
  * destroy
  * dumpxml
  * dominfo

It's only possible to have only one disk device and only one
network, which should be of type bridge.

In order to make a client-only build successful on RHEL4 (yes, you
read that correctly!), commit 3ed2e545 modified src/util/virnetdev.c so
that the functional version of virNetDevGetVLanID() was only compiled
if GET_VLAN_VID_CMD was defined. However, it is *never* defined, but
is only an enum value, so the proper version was no longer compiled
even on platforms that support it. This resulted in the vlan tag not
being properly set for guest traffic on VEPA mode guest macvtap
interfaces that were bound to a vlan interface (that's the only place
that libvirt currently uses virNetDevGetVLanID)

Since there is no way to compile conditionally based on the presence
of an enum value, this patch modifies configure.ac to check for said
enum value with AC_CHECK_DECLS(), which #defines
HAVE_DECL_GET_VLAN_VID_CMD to 1 if it's successful compiling a test
program that uses GET_VLAN_VID_CMD (and still #defines it, but to 0,
if it's not successful).  We can then make the compilation of
virNetDevGetVLanID() conditional on the value of
HAVE_DECL_GET_VLAN_VID_CMD.

LIBGLUSTER_LIBS is emptied before gluster is enabled/disabled, but nothing
else sets/uses this variable, so it can be removed.

On Fedora 20, with wireshark-devel installed, 'make rpm' failed
due to installed but unpackaged files related to wireshark.  As
F20 is already released without wireshark, I chose to add a new
sub-package that is enabled only for F21 and later.  Furthermore,
all existing wireshark plugins belong to the wireshark package,
so I got to invent behavior of how the first third-party wireshark
module will behave.

On Fedora 19 and older the pthreads impl provided with
mingw does not have any pthread_sigmask impl at all. The
configure.ac check was not distinguishing this scenario
from that of a broken pthread_sigmask impl, so was
mistakenly enabling the libvirt workaround even when it
was not needed. This in turn conflicted with the gnulib
provided pthread_sigmask impl.

This is useful in certain circumstances, for example when
libvirtd is being executed by FreeBSD rc script, it cannot find

Introduce Wireshark dissector plugin which adds support to Wireshark
for dissecting libvirt RPC protocol.
Added following files to build Wireshark dissector from libvirt source
tree.
* tools/wireshark/*: Source tree of Wireshark dissector plugin.

Added followings to configure.ac or Makefile.am.
configure.ac
* --with-wireshark-dissector: Enable support for building Wireshark
  dissector.
* --with-ws-plugindir: Specify wireshark plugin directory that dissector
  will installed.
* Added tools/wireshark/{Makefile,src/Makefile} to  AC_CONFIG_FILES.
Makefile.am
* Added tools/wireshark/ to SUBDIR.

On my Fedora 20 box with mingw cross-compiler, the build failed with:

../../src/rpc/virnetclient.c: In function 'virNetClientSetTLSSession':

     sigset_t oldmask, blockedsigs;
              ^

I traced it to the fact that mingw64-winpthreads installs a header
that does #define pthread_sigmask(...) 0, which means any argument
only ever passed to pthread_sigmask is reported as unused.  This
patch works around the compilation failure, with behavior no worse
than what mingw already gives us regarding the function being a
no-op.

* configure.ac (pthread_sigmask): Probe for broken mingw macro.
* src/util/virutil.h (pthread_sigmask): Rewrite to something that
avoids unused variables.
