The same pattern of retrieving the domXML, running the hook script, and
checking for error is used throughout the libxl driver. Remove some
repetitive code by adding a helper function to perform these tasks.

Introduce libxlDomainStartPerform as part of decomposing libxlDomainStart.
Perform all operations that are part of starting a domain. On error the
domain is destroyed from libxl's perspective, but the operations perfomed
in libxlDomainStartPrepare must be unwound by libxlDomainStart.

The 'storageMigration' flag is supposed to be true if storage migration
is requested, which is based on VIR_MIGRATE_NON_SHARED_DISK or
VIR_MIGRATE_NON_SHARED_INC flags. The assignment to the variable used
QEMU_MONITOR_MIGRATE_NON_SHARED_INC (0x04) instead of
VIR_MIGRATE_NON_SHARED_INC (0x80), caused libvirtd to skip the actual
copy of data.

When users register the threshold event for the top level image with an
explicit index (e.g. vda[3]) they are clearly expecting the index in the
event.
This flag will help avoiding emission of the second event without the
index when the client clearly requested one with the index.

When seeing a guest with a sound device, and no audio backend, we
automatically add an audio backend XML element based on the historical
QEMU driver behaviour. Unfortunately when we live migrate back to an
old libvirt, it may not understand the audio driver type we configured.
We thus need to strip the default audio backend when migrating.
