24cbacfe7a Fix src/ pkg-config API XML paths
The .pc files in src/ are intended for use with the ./run script,
to ease building bindings against an uninstalled libvirt build.
The pointer to the API XML files is incorrect though, it needs to
point into the build tree.

This fixes use of the run script for building libvirt-python, ex:

  /path/to/libvirt.git/run ./setup.py build

74ca70507a backup: Introduce virDomainBackup APIs
Introduce a few new public APIs related to incremental backups.  This
builds on the previous notion of a checkpoint (without an existing
checkpoint, the new API is a full backup, differing from
virDomainBlockCopy in the point of time chosen and in operation on
multiple disks at once); and also allows creation of a new checkpoint
at the same time as starting the backup (after all, an incremental
backup is only useful if it covers the state since the previous
backup).

A backup job also affects filtering a listing of domains, as well as
adding event reporting for signaling when a push model backup
completes (where the hypervisor creates the backup); note that the
pull model does not have an event (starting the backup lets a third
party access the data, and only the third party knows when it is
finished).

The full list of new APIs:
        virDomainBackupBegin;
        virDomainBackupGetXMLDesc;

252958ee16 backup: Document new XML for backups
Prepare for new backup APIs by describing the XML that will represent
a backup.  The XML resembles snapshots and checkpoints in being able
to select actions for a set of disks, but has other differences.  It
can support both push model (the hypervisor does the backup directly
into the destination file) and pull model (the hypervisor exposes an
access port for a third party to grab what is necessary).  Add
testsuite coverage for some minimal uses of the XML.

The <disk> element within <domainbackup> tries to model the same
elements as a <disk> under <domain>, but sharing the RNG grammar
proved to be hairy. That is in part because while <domain> use
<source> to describe a host resource in use by the guest, a backup job
is using a host resource that is not visible to the guest: a push
backup action is instead describing a <target> (which ultimately could
be a remote network resource, but for simplicity the RNG just
validates a local file for now), and a pull backup action is instead
describing a temporary local file <scratch> (which probably should not
be a remote resource).  A future refactoring may thus introduce some
way to parameterize RNG to accept <disk type='FOO'>...</disk> so that
the name of the subelement can be <source> for domain, or <target> or
<scratch> as needed for backups. Future patches may improve this area
of code.
