If we didn't find a match, either because we're cross compiling
or because we're not building on RHEL, we won't install any
init script.

Make sure this is reported correctly in the configure summary.

We use $(LN_S) for creating symbolic links, but the appropriate
autoconf macro was not included among the checks for external
programs.

So in glibc-2.23 sys/sysmacros.h is no longer included from sys/types.h
and we don't build because of the usage of major/minor/makedev macros.
Autoconf already has AC_HEADER_MAJOR macro that check where exactly
these functions/macros are defined, so let's use that.

To ensure the libvirt libxl driver will build with future versions
of Xen where the libxl API may change in incompatible ways,
explicitly use LIBXL_API_VERSION 0x040200. The libxl driver
does use new libxl APIs that have been added since Xen 4.2, but
currently it does not make use of any changes made to existing
APIs such as libxl_domain_create_restore or libxl_set_vcpuaffinity.
The version can be bumped if/when the libxl driver consumes the
changed APIs.

Further details can be found in the following discussion thread

The reason for this is to fix the automatic rebuild of libvirt-common.h.in.
All *.in files should be automatically rebuilt each time they're modified.
It works well for makefiles and pkgconfig files, since they do have a valid
dependency in the top-level Makefile. However, with libvirt-common.h.in
there is no dependency in the top-level Makefile and there's no need for it
either, so this rule

include/libvirt/libvirt-common.h: $(top_builddir)/config.status \
        $(top_srcdir)/include/libvirt/libvirt-common.h.in
    cd $(top_builddir) && $(SHELL) ./config.status $@

is never hit and should be moved to include/Makefile, but that's automake's
job. According to GNU automake docs:

"Files created by AC_CONFIG_FILES, be they
Automake Makefiles or not, are all removed by ‘make distclean’. Their inputs
are automatically distributed, unless they are the output of prior
AC_CONFIG_FILES commands. Finally, rebuild rules are generated in the Automake
Makefile existing in the subdirectory of the output file, if there is one, or
in the top-level Makefile otherwise."

Which means that if we want to have the rule for libvirt-common.h automatically
generated by automake, the include/Makefile.am needs to be moved into libvirt/
subdirectory and $SUBDIRS in the top-level Makefile need to be adjusted as
well. This patch moves Makefile.am from include/ to include/libvirt, adjusting
the prefixes accordingly as well as updates the top-level Makefile $SUBDIRS to
properly hint automake to generate all rules at proper places.

Best way to see the changes, use -M with 'git show'.

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.

Checking for the availability of this header, just like checking
for the availability of gnutls_rnd(), requires CFLAGS and LIBS to
be set appropriately.

Fixes the following compilation errors on FreeBSD:

  qemu/qemu_domain.c:640:16: error: implicit declaration of function
   'gnutls_rnd' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
      if ((ret = gnutls_rnd(GNUTLS_RND_RANDOM, key, nbytes)) < 0) {
                 ^
  qemu/qemu_domain.c:640:27: error: use of undeclared identifier
   'GNUTLS_RND_RANDOM'; did you mean 'GNUTLS_CRD_ANON'?
      if ((ret = gnutls_rnd(GNUTLS_RND_RANDOM, key, nbytes)) < 0) {
                            ^~~~~~~~~~~~~~~~~
                            GNUTLS_CRD_ANON

Our use of gnutls_rnd(), introduced with commit ad7520e8, is
conditional to the availability of the <gnutls/crypto.h> header
file.

Such check, however, turns out not to be strict enough, as there
are some versions of GnuTLS (eg. 2.8.5 from CentOS 6) that provide
the header file, but not the function itself, which was introduced
only in GnuTLS 2.12.0.

Introduce an explicit check for the function.

The variables used for storing CFLAGS and LIBS before temporarily
modifying them was consistent when it comes to the name, but not
when it comes to the case.

Make sure names are completely consistent.

The previous value of CFLAGS was saved as old_cflags but later
restored from old_CFLAGS, which is clearly not correct.

Restore CFLAGS from the right variable.

Name Service Switch is a glibc feature responsible for many
things. Translating domain names into IP addresses and vice versa
is just one of them. However, currently it's the only
functionality that this commit is tickling. Well, in this commit
the plugin skeleton is introduced. Implementation to come in next
patches.
Because of the future testing, where the implementation is to be
linked with a test, this needs to go into static library. Linking
a program with an .so statically is not portable. Therefore a
dummy libnss_libvirt_impl library is being introduced too.

We include the file in plenty of places. This is mostly due to
historical reasons. The only place that needs something from the
header file is storage_backend_fs which opens _PATH_MOUNTED. But
it gets the file included indirectly via mntent.h. At no other
place in our code we need _PATH_.*. Drop the include and
configure check then.

The migration code now doesn't need it, so remove the macros and the
configure code that is detecting it.

ZFS-on-Linux implementation of ZFS starting with version 0.6.4
contains all the features we use. Additionally, as we support
'volmode' option handling that's not available on ZoL but is
available on FreeBSD, there is no need to block ZFS storage driver
on Linux anymore.

So un-mark zfs storage driver as FreeBSD-only.

Move the logic to docs/Makefile.am, and simplify it with a wildcard

Move all the logic to include/Makefile.am, simplify it with a wildcard,

Using one Makefile per example subdirectory essentially serializes 'make'
calls. Convert to one example/Makefile that builds and distributes
all the subdir files. This reduces example/ rebuild time from about 5.8
seconds to 1.5 seconds on my machine.

One slight difference is that we no longer ship Makefile.am with the
examples in the rpm. This was virtually useless anyways since the Makefile
was very specific to libvirt infrastructure, so wasn't generically
reusable anyways.

Tested with 'make distcheck' and 'make rpm'

Add a configure option to disable virt-login-shell build even if lxc is
enabled.

This function can be used to retrieve the current locked memory
limit for a process, so that the setting can be later restored.

Add a configure check for getrlimit(), which we now use.

Rather than trying to figure out how to get dynamic loading of
vbox to work under cygwin (since I don't even have a working vbox
setup to test whether it works), I'm going to be lazy and just
default to not even trying vbox on cygwin.

Upstream Xen is in the process of splitting the (stable API) xtl_*
interfaces out from the (unstable API) libxenctrl library and into a
new (stable API) libxentoollog.

In order to be compatible with Xen both before and after this
transition check for xtl_createlogger_stdiostream in a libxentoollog
library and use it if present. If it is not present assume it is in
libxenctrl.

Compile tested on Xen 4.6 and a development tree with the split in
place.

As it turned out, we need to share some enums and declarations between
libvirt.h and libvirt-admin.h, but since our policy forbids direct includes of
libvirt*.h, there has to be some header exempt from this rule. This patch moves
the relevant part of code from libvirt.h.in to libvirt-common.h.in. Moreover,
since there is no need to have libvirt.h generated anymore, introduce a new
header libvirt.h which was previosly ignored from git and make the common
header ignored and generated instead.

So, our mingw build is broken. It's because while libvirt_shell
library is using some of our internal APIs, e.g. virStrndup, and
readline API but it's not being linked with nor libvirt.la nor
libreadline.  Only subsequent users of the library, like virsh,
do link to the needed libraries. In fact, I'm surprised Linux
linker doesn't care, because how can it make a static library
with missing symbols is mystery to me.

Since we're linking this into libvirtd we need some symbols to be public
but not part of the public API so mark them as
LIBVIRT_ADMIN_PRIVATE_<VERSION> as we do with libvirt.

Making all other symbols local makes sure we don't accidentally leak
unwanted ones.
