If we static link to libvirt_util.la then we can't override functions in
this file by simply implementing them in the test code. Any tests should
dynamic link to the main libvirt.la and ensure symbols are exported.

The redetection was originally added in 43c01d38 as a way to recover
from libvirtd upgrade from the time when we didn't persist the qemu
capabilities in the status XML. Also this the oldest supported qemu by
more than two years.

Even if somebody would have a running VM running at least qemu 1.5 with
such an old libvirt we certainly wouldn't do the right thing by
redetecting the capabilities and then trying to communicate with qemu.

For now it will be the best to just stop considering this scenario any
more and error out for such VM.

Commit c90fb5a8 added explicit use of the private copy of the qemu
capabilities to various places. The change to qemuProcessInit was bogus
though as at the point where we re-initiate the post parse callbacks
priv->qemuCaps is still NULL as we clear it after shutdown of the VM and
don't initiate it until a later point.

Using the value from priv->qemuCaps might mislead readers of the code
into thinking that something useful is being passed at that point so go
with an explicit NULL instead.

The statistics fields are used in two places:

1) virDomainGetJobStats where the job type which ultimately holds
whether the job was successful or not is returned via a different
argument.

2) The virConnectDomainEventJobCompleted event where we report just the
statistics via typed parameters.

Since it might be useful to report the event also for jobs which
completed unsuccessfully and we don't have the means to transport the
state via a different variable with the event let's add a new field
which will hold the success state.

Since this is meant primarily for completed jobs a plain boolean is
sufficient to convey whether the job was successful or not.

For managed save we can choose between various compression
methods. I randomly tested the 'xz' program on a 8 GB guest
and was surprised to have to wait > 50 minutes for it to
finish compressing, with 'xz' burning 100% cpu for the
entire time. Despite the impressive compression, this is
completely useless in the real world as it is far too long
to wait to save the VM.

The 'xz' binary defaults to '-6' optimization level which
aims for high compression, with moderate memory usage,
at the expense of speed.

This change switches it to use the '-3' optimization level
which is documented as being the one that optimizes speed
at expense of compression. Even with this, it will still
outperform all the other options in terms of compression
level. It is a little less than x4 faster than '-6' which
means it starts to be a viable choice to use 'xz' for
people who really want best compression.

The test results on a 1 GB, fairly freshly booted VM are
as follows

  format | save  | restore  size
  =======+=======+=============
  raw    |   05s |    1s  | 428 MB
  lzop   |   05s |    3s  | 160 MB
  gzip   |   29s |    5s  | 118 MB
  bz2    |   54s |   22s  | 114 MB
  xz     | 4m37s |   13s  |  86 MB
  xz -3  | 1m20s |   12s  |  95 MB

Based on this we can say

 * For moderate compression with no noticable loss in speed

       => use lzop

 * For high compression with moderate loss in speed

       => use gzip

 * For best compression with significant loss in speed

       => use xz

Commit 4b58fdf2 which enabled block copy also for network
destinations needed to limit when the 'mirror' storage source is
initialized in cases when we e.g. don't have an appropriate backend.

Limiting it just to virStorageFileSupportsCreate is too restrictive as
for example we can't precreate block devices and thus wouldn't
initialize the 'mirror' but since it's a local source we'd try to
examine it. This would fail since it wouldn't be initialized.

Fix it by introducing a more granular check whether certain operations
are supported and fix the check interlocks.
