    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!
