[libvirt] [PATCH] Add domain type checking



The drivers were accepting domain configs without checking if those
were actually meant for them. For example the LXC driver happily
accepts configs with type QEMU.

For convenience add an optional check for the domain type for the
virDomainDefParse* functions. It's optional because in some places
virDomainDefParse* is used to parse a config without caring about
it's type. Also the QEMU driver has to accept 4 different types and
does this checking own it's own.
