xen: drop XenXC and associated interface wrappers

Browse Source 
Now that 4.2 and earlier are no longer supported "xc_interface *" is
always the right type for the xc interface handle.

With this we can also simplify the handling of the xenforeignmemory
compatibility wrapper by making xenforeignmemory_handle ==
xc_interface, instead of an xc_interface* and remove various uses of &
and *h.
