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.

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.

Keep all variable declarations close together.

Use a separate variable instead of setting it inline for
slightly cleaner code.

The autoconf manual says we shouldn't be using this variable (and
some others) outside of Makefiles as it prevents users providing
their own prefix at the installation phase.

This was needed for RHEL 4 vintage distributions, which we
haven't supported for a long time now.

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:

See "Reimplementable Independently" column in the
"$NOTIFY_SOCKET Daemon Notifications" row:

Move all the UML driver related routines into m4/virt-driver-uml.m4.

We don't need them any longer; moreover, the previous structure
made it very easy for bugs to slip in, by having the result of one
check influence the following one.

By placing the check for "$with_init_script" = check front and
center, hopefully this won't happen (as easily) again.

We don't want to install legacy init scripts on modern,
systemd-native hosts.

Move the code dealing with init scripts to a separate file
so configure.ac itself can be a little bit smaller.

Our distcheck is broken. Well, it works but only by pure chance.
When wireshark plugin is enabled, we try to query which path
should the plugin be installed into. Firstly, we try to ask
pkg-config as some releases of wireshark already sets
corresponding variable in their pkg-config files. However, if we
obtained no value from there we try to construct the path on our
own. Based on our observations it usually is:
$libdir/wireshark/plugins/$version/.
Now, the problem is in the way we are deciding whether we have
obtained the plugin directory from pkg-config or not. Simply
said, we are checking wrong variable. The variable we are
checking has never been set, thus in our test is empty and
therefore we will always construct the plugin dir path on our
own, regardless of its presence in the pkg-config file.
To make things worse, after fixing this problem, VPATH build was
broken as it now tried to install plugin into correct directory.
Yes, this is problem, because --prefix was not honoured and
everything but the plugin was installed into given prefix. I've
managed to resolve this issue by replacing plugin dir prefix with
our own. So when doing regular installation (our prefix ==
wireshark prefix), nothing changes. When doing VPATH build &
installation plugin is installed into correctly prefixed dir.

virt-host-validate, just like virt-login-shell, doesn't make sense
on Windows, so we should avoid building it.

Make the tool optional and build it by default on all platforms
except Windows, erroring out if the user attempts to build it
anyway.

fdstream.c: In function 'virFDStreamWrite':
fdstream.c:390:29: error: logical 'or' of equal expressions [-Werror=logical-op]

Fedora rawhide now uses gcc 6.0 and there is a bug with -Wlogical-op
producing false warnings.

The check is supposed to stop users from trying to compile
virt-login-shell on Windows by erroring out during the
configure phase; however, there are two flaws in it:

  * the value of "x$with_win" is compared to "yes" instead
    of "xyes" (note the "x" in the first string)

  * "test" is not being used, so the script will actually
    try to run a command called "x$with_win" instead of
    performing string comparison

This patch fixes both issues.
