The xenParseXLVnuma() function is responsible for parsing 'vnuma'
part of XL config and setting corresponding values in
virDomainDef. While doing so it uses a static buffer which is set
to data we are interested in and then parsing the buffer further
(e.g. string to integer conversion, bitmap parsing, and so on).
Well, the data we are interested in are already in a string
(@data) which can be used directly rendering this intermediary
buffer needless.

The way that virConfSetValue() works (and the way it is even
documented) is that the @value pointer is always consumed.
However, since the first order pointer is passed it leaves
callers in a pickle situation - they always have to set pointer
to NULL after calling virConfSetValue() to avoid touching it.
Let's switch @value to a double pointer and clear it inside the
function.

This commit declares g_autoptr() function for virConfValue type.
At the same time, it switches variable declarations to use it.
Also, in a few places we might have freed a variable twice, for
instance in xenFormatXLDomainNamespaceData(). This is because
virConfSetValue() consumes passed pointer (@value) even in case
of failure and thus any code that uses virConfSetValue() must
refrain from touching @value and it must not call
virConfFreeValue().
This semantic is not obvious and will be addressed in one of
future commits.

The virStorageSourceParseRBDColonString() function is declared in
src/storage_file/storage_source.h and
src/storage_file/storage_source_backingstore.h but implemented
only in the .c that corresponds to the latter header file.
Therefore, drop declaration from storage_source.h as the function
is not implemented in its corresponding .c file.

Now that qemu fixed device unplug when JSON syntax is used with -device
we can re-enable the feature.
Since the old capability string representation is condemned by
suggesting filtering it as a workaround we must introduce a new string.
To achieve this the original capability position is renamed to
X_QEMU_CAPS_DEVICE_JSON_BROKEN_HOTPLUG and a new position with the
original name QEMU_CAPS_DEVICE_JSON is introduced to prevent us having
to change the rest of the code.

The qemuFirmwareOSInterfaceTypeFromOsDefFirmware method

Due to historical reasons we allow users to redefine an existing
snapshot without providing the domain definition which would correspond
to it. In such case we'd use the domain definition from the snapshot
that is being redefined.
To prevent callers from doing complex moving of the domain definition
object back and forth between the snapshot definitions we can add an
argument to virDomainSnapshotAlignDisks which will allow us to pass in
the alternate definition if the one from the snapshot is missing.

'require_match' set to true is only needed for internal snapshots taken

To de-clutter callers we can change the argument to mean 'this code path
requires uniform snapshot for internal snapshots'.
Change the argument and fix the callers. For now all callers pass 'true'
