xen: make use of xen_xc implicit in xen_common.h inlines
Doing this will make the transition to using the new libxendevicemodel
interface less intrusive on the callers of these functions, since using
the new library will require a change of handle.
NOTE: The patch also moves the 'externs' for xen_xc and xen_fmem from
xen_backend.h to xen_common.h, and the declarations from
xen_backend.c to xen-common.c, which is where they belong.
