These days libvirt is pretty reliable and even remote connections
(not the default for libvirt-guests anyway) either work or fail but are
uncommon to be flaky.
On the other hand users might have disabled the service and while we are
After=libvirtd for ordering we are not Requiring it. Adding that or any
harder dependency might break our ordering. But if people have disabled
libvirt they will do a full retry loop until timeout.
Lets drop the loop to be much faster if a remote is not reachable.

The race described in that commit no longer exists using systemd as
we now have socket activation. If not using systemd, then it is also
safe if using the libvirtd --daemon flag, since the parent process
won't return to the caller until the child is accepting connections.

The cause was apparently incorrect handling of jobs in snapshot
revert code which allowed a thread executing snapshot delete to
begin job while snapshot revert was still running on another
thread. The snapshot delete thread then waited on a condition
variable in qemuMonitorSend() while the revert thread finished,
changing (and effectively corrupting) the qemuMonitor structure
under the delete thread which led to its crash.
The incorrect handling of jobs in revert code was due to the fact
that although qemuDomainRevertToSnapshot() correctly begins a job
at the start, the job was implicitly ended when qemuProcessStop()
was called because the job lives in the QEMU driver's private
data (qemuDomainObjPrivate) that was purged during
qemuProcessStop().
This fix prevents qemuProcessStop() from clearing jobs as the
idea of qemuProcessStop() clearing jobs seems wrong in the first
place. It was (inadvertently) introduced in commit 888aa4b6b9db65e3db273341e79846, which is effectively reverted by

When QEMU uid/gid is set to non-root this is pointless as if we just
used a regular setuid/setgid call, the process will have all its
capabilities cleared anyway by the kernel.
When QEMU uid/gid is set to root, this is almost (always?) never
what people actually want. People make QEMU run as root in order
to access some privileged resource that libvirt doesn't support
yet and this often requires capabilities. As a result they have
to go find the qemu.conf param to turn this off. This is not
viable for libguestfs - they want to control everything via the
XML security label to request running as root regardless of the
qemu.conf settings for user/group.
Clearing capabilities was implemented originally because there
was a proposal in Fedora to change permissions such that root,
with no capabilities would not be able to compromise the system.
ie a locked down root account. This never went anywhere though,
and as a result clearing capabilities when running as root does
not really get us any security benefit AFAICT. The root user
can easily do something like create a cronjob, which will then
faithfully be run with full capabilities, trivially bypassing
the restriction we place.
IOW, our clearing of capabilities is both useless from a security
POV, and breaks valid use cases when people need to run as root.
This removes the clear_emulator_capabilities configuration
option from qemu.conf, and always runs QEMU with capabilities
when root. The behaviour when non-root is unchanged.

qemu: block: store the delete flag in libvirtd's status XML
Since blockcommit is asynchronous, libvirtd can be restarted while the
operation runs. To ensure the information necessary to finish up the job
is not lost, serialisation to and deserialisation from the status XML is
added.
To unittest this, the new element was only added to the active commit test,
the non-active commit test doesn't have the new element so as to test its
absence.

qemu: block: use the delete flag to delete snapshot images if requested
When blockcommit finishes successfully, one of the
qemuBlockJobProcessEventCompletedCommit() and
qemuBlockJobProcessEventCompletedActiveCommit() event handlers is called.
This is where the delete flag (stored in qemuBlockJobCommitData since the
previous commit) can actually be used to delete the committed snapshot
images if requested.
We use virFileRemove() instead of a simple unlink() to cover the case where
the image to be removed is on an NFS volume.

qemu: block: propagate the delete flag to where it can actually be used
Propagate the delete flag from qemuDomainBlockCommit() (which was just
ignoring it until now) to qemuBlockJobDiskNewCommit() where it can be
stored in the qemuBlockJobCommitData structure which holds information
necessary to finish the job asynchronously.
In the actual qemuBlockJobDiskNewCommit() in this commit, we temporarily
pass a literal 'false' to preserve the current behaviour until the whole
implementation of the feature is in place.

lxc: Refresh capabilities if they have never been initalized
Adjust virLXCDriverGetCapabilities to fill in driver->caps if it is
empty, regardless of the passed 'refresh' value. This matches the
pattern used in virQEMUDriverGetCapabilities
This fixes LXC XML startup parsing for me

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
