Detection based on gnutls_session doesn't work because GnuTLS 2.x.y
comes with a compat.h that defines gnutls_session to gnutls_session_t.

Instead detect this based on LIBGNUTLS_VERSION_MAJOR. Move this from
configure/config.h to gnutls_1_0_compat.h and make sure that all users
include gnutls_1_0_compat.h properly.

Also fix header guard in gnutls_1_0_compat.h.

Right now, every re-run of configure re-evaluates whether a
static analysis tool is in use.  But if you run configure under
coverity, make a tweak, and then do an incremental rebuild with
gcc but not coverity to test the tweak, then rerun a build under
coverity, then configure does not get rerun, and static analysis
ends up with lots of false positives.

This patch caches the static analysis result, and also makes it
easier to force static analysis even if the existing checks are
insufficient to detect newer versions of the static analyzer tools.

* configure.ac (lv_cv_static_analysis): New cache variable.

Gettext annoyingly modifies CPPFLAGS in-place, putting
-I/usr/local/include into the search patch if libintl headers
must be used from that location.  But since we must support
automake 1.9.6 which lacks AM_CPPFLAGS, and since CPPFLAGS is used
prior to INCLUDES, this means that the build picks up the _old_
installed libvirt.h in priority to the in-tree version, leading
to all sorts of weird build failures on FreeBSD.

Fix this by teaching configure to undo gettext's actions, but
to keep any changes required by gettext at the end of INCLUDES
after all in-tree locations are used first.  Also requires
adding a wrapper Makefile.am and making gnulib-tool create
just gnulib.mk files during the bootstrap process.

I went with the shorter license notice used by src/libvirt.c,

Even though gnutls is a hard-req for libvirt, and gnutls depends
on libtasn1, that does not mean that you have to have the libtasn1
development files installed.  Skip the test rather than failing
compilation in that case.

With newer gcc, the test consumed too much stack space.  Move
things to static storage to fix that.

Required for a coming patch where iohelper will operate on O_DIRECT
fds.  There, the user-space memory must be aligned to file system
boundaries (at least 512, but using page-aligned works better, and
some file systems prefer 64k).  Made tougher by the fact that
VIR_ALLOC won't work on void *, but posix_memalign won't work on
char * and isn't available everywhere.

This patch makes some simplifying assumptions - namely, output
to an O_DIRECT fd will only be attempted on an empty seekable
file (hence, no need to worry about preserving existing data
on a partial block, and ftruncate will work to undo the effects
of having to round up the size of the last block written), and
input from an O_DIRECT fd will only be attempted on a complete
seekable file with the only possible short read at EOF.

* configure.ac (AC_CHECK_FUNCS_ONCE): Check for posix_memalign.
* src/util/iohelper.c (runIO): Use aligned memory, and handle
quirks of O_DIRECT on last write.

V2: Remove policy kit references from virNetServer and use DBus APIs

Currently, the xen statstest and reconnect tests are only compiled

This guts the libvirtd daemon, removing all its networking and
RPC handling code. Instead it calls out to the new virServerPtr
APIs for all its RPC & networking work

As a fallout all libvirtd daemon error reporting now takes place
via the normal internal error reporting APIs. There is no need
to call separate error reporting APIs in RPC code, nor should
code use VIR_WARN/VIR_ERROR for reporting fatal problems anymore.

If macvtap is required then libnl has to be available, otherwise
libnl is optional.

Since the addition of the lock manager framework in 6a943419
dlopen is always required, but the checks in configure wasn't changed
to reflect that. This didn't show up directly because the VirtualBox
driver linking dlopen in covered it. But disabling the VirtualBox
driver makes the build fail due to missing dlopen.

Change the dlopen check in configure to pick up dlopen when available.

In between fork and exec, a connection to sanlock is acquired
and the socket file descriptor is intionally leaked to the
child process. sanlock watches this FD for POLL_HANGUP to
detect when QEMU has exited. We don't want a rogus/compromised
QEMU from issuing sanlock RPC calls on the leaked FD though,
since that could be used to DOS other guests. By calling
sanlock_restrict() on the socket before exec() we can lock
it down.

* src/locking/domain_lock.c: Restrict lock acquired in
  process startup phase
* src/locking/lock_driver.h: Add VIR_LOCK_MANAGER_ACQUIRE_RESTRICT

Sanlock is a project that implements a disk-paxos locking
algorithm. This is suitable for cluster deployments with
shared storage.

* src/Makefile.am: Add dlopen plugin for sanlock
* src/locking/lock_driver_sanlock.c: Sanlock driver
* configure.ac: Check for sanlock

Remove some special case code that took care of mapping hyper to the
correct C types.

As the list of procedures that is allowed to map hyper to long is fixed
put it in the generator instead annotations in the .x files. This
results in simpler .x file parsing code.

Use macros for hyper to long assignments that perform overflow checks
when long is smaller than hyper. Map hyper to long long by default.

Suggested by Eric Blake.

As OpenVZ is Linux specific.

This is the functionality at the end of the libvirt part of the call
chain - for each function, the corresponding netcf API is called.

Now that RHEL 5.6 ships with gettext 0.17, we can get out of the
stone age and use the newer gettext capabilities and improved

(MKINSTALLDIRS): Delete hack that is no longer needed.
* bootstrap.conf (buildreq): Check for minimum gettext version.

glibc 2.13.90 has obsoleted its rpc implementation in favour of
the one provided by the TI-RPC library:

>   Programs in need of RPC functionality must be linked against TI-RPC.
>   The TI-RPC implemtation is IPv6 enabled and there are other benefits.

>   Implemented by Ulrich Drepper.
(from glibc NEWS)

Thus with recent glibc, we need to try linking with -ltirpc when looking
for the XDR functions. The daemon also needs to use XDR_CFLAGS to be able
to find the XDR headers stored in /usr/include/tirpc.

When using TI-RPC, there are some warnings about redundant declarations, but
the fix probably belongs in other modules:

/usr/include/tirpc/rpc/rpcent.h:68:13: warning: redundant redeclaration of
'setrpcent' [-Wredundant-decls]
/usr/include/rpc/netdb.h:53:13: note: previous declaration of 'setrpcent'
was here

/usr/include/tirpc/rpc/rpcent.h:69:13: warning: redundant redeclaration of
'endrpcent' [-Wredundant-decls]
/usr/include/rpc/netdb.h:54:13: note: previous declaration of 'endrpcent'
was here

/usr/include/tirpc/rpc/rpc.h:84:12: warning: redundant redeclaration of
'bindresvport' [-Wredundant-decls]
/usr/include/netinet/in.h:440:12: note: previous declaration of
'bindresvport' was here

Version 2.0.0 or yajl changed API. It is fairly trivial for us to
cope with both APIs in libvirt, so adapt.

* configure.ac: Probe for yajl2 API
* src/util/json.c: Conditional support for yajl2 API

* configure.ac libvirt.spec.in docs/news.html.in: update and document

* po/*.po*: update localizations for german, polish, spanish, ukrainian

In Fedora 15, with clang 2.8, 'scan-build env' shows:
CCC_ANALYZER_ANALYSIS=-analyzer-check-objc-mem -analyzer-check-security-syntactic -analyzer-check-dead-stores -analyzer-check-objc-unused-ivars -analyzer-check-objc-methodsigs

But in rawhide, with clang 2.9, the same variable is set but
empty, implying the default set of analysis.  We still want
sa_assert defined in that case, to stop clang from hitting
false positives.

* configure.ac (STATIC_ANALYSIS): Detect clang even when the set
of analyses is the default.

Currently the build fails if /usr/local/include does not exist since
its use is hardcoded in configure.ac

Check for audit_encode_nv_string in libaudit so that ancient audit
library is ignored rather than trying to compile with libaudit support

If one specify "--with-python=yes" but no python-devel package

doesn't give clear guide to user.

Remove custom code for checking compiler warnings, using
gl_WARN_ADD instead. Don't list all flags ourselves, use
gnulib's gl_MANYWARN_ALL_GCC to get all possible GCC flags,
then turn off the ones we don't want yet.

* acinclude.m4: Rewrite to use gl_WARN_ADD and gl_MANYWARN_ALL_GCC
* bootstrap.conf: Add warnings & manywarnings
* configure.ac: Switch to gl_WARN_ADD
