Subject: [PATCH] destroy: Define new public API virDomainDestroyFlags

This introduces new API virDomainDestroyFlags to allow
domain destroying with flags, as the existing API virDomainDestroy
misses flags.

The set of flags is defined in virDomainDestroyFlagsValues enum,
which is currently commented, because it is empty.

Calling this API with no flags set (@flags == 0) is equivalent calling
virDomainDestroy.
