Excise XEN specific code out of x86/x86/intr.c into xen/x86/xen_intr.c

While at it, separate the source function tracking so that the interrupt
paths are truly independant.

Use weak symbol exporting to provision for future PVHVM co-existence
of both files, but with independant paths. Introduce assembler code
such that in a unified scenario, native interrupts get first priority
in spllower(), followed by XEN event callbacks. IPL management and
semantics are unchanged - native handlers and xen callbacks are
expected to maintain their ipl related semantics.

In summary, after this commit, native and XEN now have completely
unrelated interrupt handling mechanisms, including
intr_establish_xname() and assembler stubs and intr handler
management.

Happy Christmas!
