This patch implements the VIR_DOMAIN_STATS_BLOCK group of statistics.
To do so, a helper function to get the block stats of all the disks of
a domain is added.

This patch implements the VIR_DOMAIN_STATS_VCPU group of statistics. To
do so, this patch also extracts a helper to gather the vCPU information.

Future patches which will implement more bulk stats groups for QEMU will
need to access the connection object.
To accommodate that, a few changes are needed:
* enrich internal prototype to pass qemu driver object
* add per-group flag to mark if one collector needs monitor access or not
* If at least one collector of the requested stats needs monitor access
we must start a query job for each domain. The specific collectors
will run nested monitor jobs inside that.
* If the job can't be acquired we pass flags to the collector so
specific collectors that need monitor access can be skipped in order
to gather as much data as is possible.

The test is loosely inspired from qemucapabilitiestest
and qemuxml2xmltest.
Added a new test instead of extending an existing one because
the feature being tested don't really fits nicely in any
existing place.
This patch adds an element to QEMU's capability XML, to
show if the underlying QEMU binary supports the live disk
snapshotting or not.
This allows any client to know ahead of time if the feature
is available.
Without this information available, the only way to check
for the snapshot support is to request one and check for
errors.

spice-server offers an API to disable file transfer messages
on the agent channel between the client and the guest.
This is supported in qemu through the disable-agent-file-xfer option.
This patch exposes this option to libvirt.
Adds a new element 'filetransfer', with one property,
'enable', which accepts a boolean.
Default is enabled, for backward compatibility.
Depends on the capability exported in the first patch of the series.

This patch detects if QEMU supports this option, and add
a capability if does.
