[PATCH 05/12] xen: don't include asm/hypercall.h from C sources

Instead of including asm/hypercall.h always use xen/hypercall.h.
Additionally include xen/hypercall.h from all sources containing a
hypercall handler.

This prepares for generating the handlers' prototypes at build time.

Add a guard in asm/hypercall.h to catch direct inclusion.
