Reorganise sources to make it possible to include Xen PVHVM support in
native kernels. Among others:
- move xen/include/amd64/hypercall.h to amd64/include/xen and
  xen/include/i386/hypercall.h to i386/include/xen
- exclude some native files from the build for xenpv
- add xen to "machine" config statement for amd64 and i386
- split arch/xen/conf/files.xen to arch/xen/conf/files.xen (for pv drivers)
  and arch/xen/conf/files.xen.pv (for full pv support)
- add GENERIC_XENHVM kernel config which includes GENERIC and add Xen PV
  drivers.

Bifurcate the interrupt establish functions between XEN and non-XEN

Thus intr_establish_xname() becomes xen_intr_establish_xname() etc.

One consequence of this is that dom0 devices expect the native
function calls to be available and we thus provide weak aliasing for
dom0 builds to succeed. XEN and non-XEN devices are distinguished by
the PIC they are established on. XEN interrupts are exclusively
established on xen_pic, while dom0 interrupts are established on
natively available PICs.

This allows us an orthogonal path to xen device management (eg:
xenstore events) in XENPVHVM, without having to worry about unifying
the vector entry paths, etc., which is quite challenging.
