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.

Storing the libvirt.pot file is a bad idea because it is an
automatically generated file. Most patches will invalidate the stored
libvirt.pot file by changing line numbers or introducing/removing files
with translatable content.

Anyone working with a libvirt GIT checkout who needs the libvirt.pot is
better served creating a fresh copy with "make libvirt.pot".

libvirt.pot is still included in the release dists, so those building
from tarballs see no change in behaviour.

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.

On Core i5 650 x86_64 kvm guest fail to start with error [1] for next cpu config:

  <cpu mode='host-model' check='partial'>
    <model fallback='allow'/>
    <feature policy='require' name='x2apic'/>
  </cpu>

The problem is in full CPU calculation in virQEMUCapsInitHostCPUModel.
It is supposed to include features emulated by qemu and missed on host. Some of
such features may be not included however.

For Core i5 650  host CPU is detected as Westmere and reported CPU as
SandyBridge. x2apic is missed on host and provided by installed qemu. The
feature is not mentioned in reported CPU features explicitly because SandyBridge
model include it. As a result full CPU does not include x2apic too.

Solution is to expand guest cpu features before updating fullCPU features.

[1] error: the CPU is incompatible with host CPU: \
       Host CPU does not provide required features: x2apic

So far we are repeating the following lines over and over:

  if (!(virSomeObjectClass = virClassNew(virClassForObject(),
                             "virSomeObject",
                             sizeof(virSomeObject),

      return -1;

While this works, it is impossible to do some checking. Firstly,
the class name (the 2nd argument) doesn't match the name in the
code in all cases (the 3rd argument). Secondly, the current style
is needlessly verbose. This commit turns example into following:

  if (!(VIR_CLASS_NEW(virSomeObject,
                      virClassForObject)))
      return -1;
