vfio/common: Move legacy VFIO backend code into separate container.c

Browse Source 
Move all the code really dependent on the legacy VFIO container/group
into a separate file: container.c. What does remain in common.c is
the code related to VFIOAddressSpace, MemoryListeners, migration and
all other general operations.
