Pkg-config file libxml-2.0.pc was introduced in libxml2-2.2.4 and we
require at least 2.6.0 so the crazy xml2-config check can be dropped.

This allows to use two or more LIBVIRT_CHECK_(LIB|LIB_ALT|PKG) macros
for one library. For example, when we check for existence of
pgk-config file of some library and we know that not all versions of
that library that libvirt requires provides this file, we can fallback
to use library check.

Usage of AC_REQUIRE will mess with order how LIBVIRT_CHECK_* macros
are composed into configure.ac. This ensures that the output of
configure --help is properly ordered and grouped into sections.

Following patch will update LIBVIRT_CHECK_(LIB|LIB_ALT|PKG) macros in
a way that you will be able to call a another macro as a fallback if
the first one fails. To allow that, we need to move the
LIBVIRT_ARG_WITH out of those macro to not have two or more same lines
in output of "configure --help".

All checks that prints result at the end of configure uses
LIBVIRT_RESULT_${CHECK_NAME}. Create those macros for remaining check.

The *header_name* cannot be quoted, otherwise it is not translated to
the passed argument. Without this fix the generated configure contains
*ac_cv_header_header_name*, but there should be for example
*ac_cv_header_sals_sasl_h* for "sasl/sasl.h".

Implement a new libssh transport, which uses libssh to communicate with
remote hosts, and add all the build system stuff (search of libssh,
private symbols, etc) to built it.
This new transport supports all the common ssh authentication methods,
making use of libvirt's auth callbacks for interaction with the user.
${exec_prefix} and ${prefix} point to the same directory in
most setups, but when that's not the case the former should
be used for architecture-dependent data such as shared objects,
which makes it the best fit for our Wireshark dissector.
While at it, change all uses of $(var) to ${var}: they are
absolutely identicaly as far as make's concerned, but autoconf
itself seems to prefer the latter form so we might as well
follow suit.
We only need to strip $ws_prefix from $ws_plugindir if we've
retrieved it from pkg-config: if we're building it ourselves
from $libdir, we can just use it without further processing.
This fixes a build issue with old gnutls.

Commit d8a8af3492 changed the minimal required version of gnutls
so it's safe to remove the code for older versions.

Since we're using autoconf to substitute the right value in
Makefile.am now, we can use a less generic name without running
into circular dependencies.
Adding $(prefix) in Makefile.am, as we were doing, means that
it would be prepended even when using --with-ws-plugindir,
which is something we don't want to happen.
Instead, we add it beforehand but take care that it doesn't
get expanded until make is called.
Even when we're building $plugindir ourselves because we can't
retrieve it using pkg-config, we still want to strip the prefix,
except in that case it would be the same prefix we're using for
building libvirt.
The fact that $plugindir is missing also doesn't tell us
anything about $ws_prefix, so we have to handle the two variables
separately.
Running the output of qemu -help doesn't make any sense. We should be
looking for libvirt being mentioned in the output. This worked by
accident, let's make it work as expected it to.

Currently, we are checking for sanlock_add_lockspace_timeout
which is good for now. But in a subsequent patch we are going to
use sanlock_write_lockspace (which sets an initial value for io
timeout for sanlock). Now, there is no reason to check for both
functions in sanlock library as the sanlock_write_lockspace was
introduced in 2.7 release and the one we are currently checking
for in the 2.5 release. Therefore it is safe to assume presence
of sanlock_add_lockspace_timeout when sanlock_write_lockspace
is detected.
Moreover, the macro for conditional compilation is renamed to
HAVE_SANLOCK_IO_TIMEOUT (as it now encapsulates two functions).

So, when building wireshark plugin, we get the plugindir variable
from the wireshark.pc as well as prefix. Then we replace the
prefix in the plugindir with our own prefix where libvirt is
building to:
plugindir="${prefix}${plugindir#ws_prefix}"
However, as you can see, there's '$' missing in front of the
ws_prefix variable. This results in the mangled plugindir, for
instance like this:
plugindir='/usr/usr/lib64/wireshark/plugins'

Unconditionally use gnulib's getopt module. This is needed by the bhyve driver
to provide a reentrant interface for getopt.
Several gnulib headers rely on features.h being included by ctype.h to provide
__GNUC_PREREQ, but on systems without glibc, this is not provided. In these
cases __GNUC_PREREQ gets redefined to 0, which causes build errors from checks
in src/internal.h.
Therefore, define __GNUC_PREREQ as early as possible. config-post.h is probably
the first header that is included, before any other headers.
Currently, virt-login-shell is not allowed to build on Windows.
However, as it's designed around LXC, it does not make sense to
build it on anything but Linux, so make the check stricter and allow to
enable it on Linux only.
The sd_notify method is used to tell systemd when libvirtd
has finished starting up. All it does is send a datagram
containing the string parameter to systemd on a UNIX socket
named in the NOTIFY_SOCKET environment variable. Rather than
pulling in the systemd libraries for this, just code the
notification directly in libvirt as this is a stable ABI
from systemd's POV which explicitly allows independant
implementations:

"$NOTIFY_SOCKET Daemon Notifications" row:
