Now that we're storing libvirt.pot in git, it will be in srcdir instead
of builddir. Weblate is responsible for running msgmerge when the .pot
file changes, so add a warning that this target is not for general usage.

To integrate with weblate the only practical option currently is to
store the .pot file in git. This is required so that it can add new
languages by cloning the .pot file. It also enables weblate to run
msgmerge on the languages whenever pulling in new changes from git.
The pot file will have to be the full content including the source
locations, so this is going to result in unpleasant diffs when it
is updated periodically.

We previously adopted a minimization technique for po files which
stripped source locations and non-translated msgids in order to save
space in the git repos and have saner commit diffs.
At this time it is not possible to integrate with weblate while having
non-translated msgids stripped, as it will immediately add them back
again.
By keeping all non-translated msgids, our .po files are about x2 the
size at 37 MB vs the original 18 MB. This is still way better than the
original po/ directory which was 109 MB. We're saving 38 MB by still
omitting source file locations, and another 34 MB are saved by the
dropping of all languages which are 100% untranslated.

The .po files are stored with strings in alphabetical order instead of
source file location order, because this minimizes the diffs created
when code moves around within or between files.
By default msgmerge will honour the order of strings in the .pot file
when creating a .po file, so it is useful if we also create the .pot
file with desired ordering.

A .mini.po file is exactly the same format as a .po file. We just used
the alternative extension as we wanted to be able to store both full and
minimized forms in the same directory.
This complicates integration with some translation tools, however, which
only really expect to see $LANG.po as a filename.
With this change we drop the rules for creating non-minimized po files,
and thus the po/*.po are always minimized. A useful side effect is that
we no longer run msgmerge during creation of the gmo files, and thus
don't need to have a date override to get reproducible builds.

When building RPMs for libvirt the PO files are part of libvirt-libs
package. Now that we generate libvirt.pot during build time the POT
creation date is also generated at that time.
The issue here is that when building libvirt-libs for x86_64 and i686
the generated libvirt.pot file will have different POT creation date
which affects installed PO files as well which leads to conflict when
installing both x86_64 and i686 packages.

Similar to the libvirt.pot, .po files contain line numbers and file
names identifying where in the source a translatable string comes from.
The source locations in the .po files are thrown away and replaced with
content from the libvirt.pot whenever msgmerge is run, so this is not
precious information that needs to be stored in git.
When msgmerge processes a .po file, it will add in any msgids from the
libvirt.pot that were not already present. Thus, if a particular msgid
currently has no translation, it can be considered redundant and again
does not need storing in git.
When msgmerge processes a .po file and can't find an exact existing
translation match, it will try todo fuzzy matching instead, marking such
entries with a "# fuzzy" comment to alert the translator to take a
look and either discard, edit or accept the match. Looking at the
existing fuzzy matches in .po files shows that the quality is awful,
with many having a completely different set of printf format specifiers
between the msgid and fuzzy msgstr entry. Fortunately when msgfmt
generates the .gmo, the fuzzy entries are all ignored anyway. The fuzzy
entries could be useful to translators if they were working on the .po
files directly from git, but Libvirt outsourced translation to the
Fedora Zanata system, so keeping fuzzy matches in git is not much help.
Finally, by default msgids are sorted based on source location. Thus, if
a bit of code with translatable text is moved from one file to another,
it may shift around in the .po file, despite the msgid not itself changing.
If the msgids were sorted alphabetically, the .po files would have
stable ordering when code is refactored.
This patch takes advantage of the above observations to canonicalize
and minimize the content stored for .po files in git. Instead of storing
the real .po files, we now store .mini.po files.
The .mini.po files are the same file format as .po files, but have no
source location comments, are sorted alphabetically, and all fuzzy
msgstrs and msgids with no translation are discarded. This cuts the size
of content in the po directory from 109MB to 19MB.
Users working from a libvirt git checkout who need the full .po files
can run "make update-po", which merges the libvirt.pot and .mini.po
file to create a .po file containing all the content previously stored
in git.
Conversely if a full .po file has been modified, for example, by
downloading new content from Zanata, the .mini.po files can be updated
by running "make update-mini-po". The resulting diffs of the .mini.po
file will clearly show the changed translations without any of the noise
that previously obscured content. Being able to see content changes
clearly actually identified a bug in the zanata python client where it
was adding bogus "fuzzy" annotations to many messages:
https://bugzilla.redhat.com/show_bug.cgi?id=1564497
Users working from libvirt releases should not see any difference in
behaviour, since the tarballs only contain the full .po files, not the
.mini.po files.
As an added benefit, generating tarballs with "make dist", will no
longer cause creation of dirty files in git, since it won't touch the
.mini.po files, only the .po files which are no longer kept in git.
To avoid creating a single commit 100+MB in size, each language is
minimized separately in a following commit.

Historically we have relied on autopoint/gettextize to install a
standard po/Makefile.in.in. There is very limited scope for customizing
this and it also causes a bunch of extra stuff to be pulled into
configure.ac which potentially clashes with gnulib. Writing make rules
for po file management is no more difficult than any other rules libvirt
has, so stop using autopoint/gettextize.
