Vim has trouble figuring out the filetype automatically because
the name doesn't follow existing conventions; annotations like

Unfortunately the data reported by pkg-config is not completely
accurate, so until the issue has been fixed in readline we need
to work around it in libvirt.

The good news is that we only need the fix to land in FreeBSD
ports and macOS homebrew before we can drop the kludge, so
we're talking months rather than years.

With the 7.0 release, readline has finally started shipping
pkg-config support in the form of a readline.pc file.

Unfortunately, most downstreams have yet to catch up with this
change: among Linux distributions in particular, Fedora Rawhide
seems to be the only one installing it at the moment.

Non-Linux operating systems have been faring much better in
this regard: both FreeBSD (through ports) and macOS (through
homebrew) include pkg-config support in their readline package.

This is great news for us, since those are the platforms where
pkg-config is more useful on account of them installing headers
and libraries outside of the respective default search paths.

Our implementation checks whether readline is registered as a
pkg-config package, and if so obtains CFLAGS and LIBS using the
tool; if not, we just keep using the existing logic.

This commit is best viewed with 'git show -w'.

The first implementation of this logic was introduced with
commit 2ec759fc all the way back in 2007; looking at the
build logs from our CI environment, however, it's apparent
that none of the platforms we currently target are actually
using it, so we can assume whatever issue it was working
around has been fixed at some point in the last 12 years.

The current code is a bit awkward, and we're going to need
to share it later anyway. We can drop the call to AC_SUBST()
while we're at it, since LIBVIRT_CHECK_LIB() already marks
READLINE_CFLAGS for substitution.

The new code goes to some extra length to avoid setting
-D_FUNCTION_DEF twice: this is mostly for cosmetic reasons,
and it's necessary because LIBVIRT_CHECK_READLINE() is called
twice: once on its own, and then once more as part of
LIBVIRT_CHECK_BASH_COMPLETION().

Firstly, virCommandRun() does report an error on failure (which
in most cases is more accurate than what we overwrite it with).
Secondly, usually errno is not set (or gets overwritten in the
cleanup code) which makes virReportSystemError() report useless
error messages. Drop all virReportSystemError() calls in cases
like this (I've found three occurrences).

The firewalld package in Fedora 30 didn't get support for rich rule
priorities, which is required by the libvirt zonefile that's installed
when the build is configured with --with-firewalld-zone, so we need to
set --without-firewalld-zone for that version of Fedora. The needed
feature is already upstream in firewalld, so it just needs another
upstream release to be there. Let's be optimistic and assume that will
happen prior to F31.

Change the Travis CI configuration to invoke the new ci-build@$IMAGE
target instead of directly running Docker. This guarantees that when a
developer runs ci-build@$IMAGE locally, the container build setup is

The Travis CI system uses Docker containers for its build environment.
These are pre-built and hosted under quay.io/libvirt so that developers
can use them for reproducing problems locally.

Getting the right Docker command syntax to use them, however, is not
entirely easy. This patch addresses that usability issue by introducing
some make targets. To run a simple build (aka 'make all') using the
Fedora 28 container:

   make ci-build@fedora-28

To also run unit tests

   make ci-check@fedora-28

This is just syntax sugar for calling the previous command with a
custom make target

   make ci-build@fedora-28 CI_MAKE_ARGS="check"

To do a purely interactive build it is possible to request a shell

   make ci-shell@fedora-28

To do a MinGW build, it is currently possible to use the fedora-rawhide
image and request a different configure script

   make ci-build@fedora-rawhide CI_CONFIGURE=mingw32-configure

It is also possible to do cross compiled builds via the Debian containers

   make ci-build@debian-9-cross-s390x

In all cases the GIT source tree is cloned locally into a 'ci-tree/src'
sub-directory which is then exposed to the container at '/src'. It is
setup to use a separate build directory so the build takes place in a
subdir '/src/build'. A source tree build can be requested instead
by passing an empty string CI_VPATH= arg to make.

The make rules are kept in a standalone file that is included into the
main Makefile.am, so that it is possible to run them without having to
invoke autotools first.

It is neccessary to disable the gnulib submodule commit check because
this fails due to the way we have manually cloned submodule repos as
primary git repos with their own .git directory, instead of letting
git treat them as submodules in the top level .git directory.

Few of the scripts in build-aux are included in EXTRA_DIST. This is not
a serious problem since they are primarily tools intended for developers
upstream, and downstream builds won't need them. Having them missing,
however, complicates downstream patching because it means patches that
are auto-exported from git will fail to apply if they include a change
to a file in build-aux/.  By bundling all these scripts in the dist we
make patching more straightforward.
