Our build system doesn't currently install the various
example programs provided along libvirt; however, both the
upstream .spec file and the Debian packaging go out of
their way to make sure these useful demos are included in
the respective documentation packages.
Moreover, doing so without help from the upstream build
system is easy to get wrong: the libvirt-docs RPM package,
for example, ends up missing one of the examples and
including a bunch of empty .deps/ directories.
Install the examples in $(docdir) as part of our regular
procedure, so that users and downstreams don't have to do
anything special about them.

At the moment we allow the user to specify exactly where
they want the HTML documentation to be installed with an
extreme level of precision through the --with-html-dir and
--with-html-subdir configure options.
Most of the time, of course, the user will stick with the
default, that is $(datadir)/doc/$(PACKAGE)-$(VERSION)/html.
So close to $(docdir)! Including the version number in
the path, specifically, seems entirely unnecessary since
different releases of libvirt are not going to be able to
coexist on the same system anyway.
Drop all these custom flexibilty for flexibilty's sake

In refactoring the snapshot code to prepare for checkpoints, I changed
qemuDomainMomentDiscardAll to take a callback that would handle the
cleanup of either a snapshot or a checkpoint, but failed to set the
callback on one of the two snapshot callers. As a result, 'virsh
undefine $dom --snapshots-metadata' crashed on a NULL function
dereference.

If no board was detected then VIR_REALLOC_N() done at the end of

Commit 105756660f was too eager and did
not consider SLES 12 which still has 2.0.1 that does not ship

Similar to how we check for readline, prefer pkg-config if available
and fall back to the old detection code if not found.

VIR_CLASS_NEW insists that descendents of virObject have 'parent' as
the name of their inherited base class member at offset 0. While it
would be possible to write a new class-creation macro that takes the
actual field name 'current', and rewrite VIR_CLASS_NEW to call the new
macro with the hard-coded name 'parent', it seems less confusing if
all object code uses similar naming. Thus, this is a mechanical rename
in preparation of making virDomainSnapshotDef a descendent of
virObject.

Previously, init_syms() was called from stat() mock and its
friends. This is crucial because checkPath() might call
printFile() which in turn calls real_fopen(). But if stat() or
one of its friends is the first function called then because of
lacking init_syms() call no real_* is initialized.
The other thing is that we really want the recorded action to be
"stat" instead of __FUNCTION__ because there's no good in
recording that it was __xstat64 who touched some file.

Commits 4bc42986 and 218c81ea removed virDomainStorageSourceFormat on
the grounds that there were no external callers; however, the upcoming
backup code wants to output a <target> (push mode) or <scratch> (pull
mode) element that is in all other respects identical to a domain's
<source> element, where the previous virDomainStorageSourceFormat fit
the bill nicely. But rather than reverting the commits, it's easier to
just add an additional parameter for the element name to use, and
update all callers.
