    Fix early page allocation on Xen
    
    The Xen target was completely ignored when porting the biosmem and
    vm_page physical memory allocators. Let's fix this.
    
    * i386/Makefrag.am (libkernel_a_SOURCES): Add i386/i386at/biosmem.{c,h}.
    * i386/i386/vm_page.h (VM_PAGE_MAX_SEGS, VM_PAGE_DIRECTMAP_LIMIT,
    VM_PAGE_HIGHMEM_LIMIT): Define for Xen.
    * i386/i386at/biosmem.c: Include mach/xen.h.
    (biosmem_panic_setup_msg): Comment out for Xen since it's unused.
    (biosmem_map_build, biosmem_map_build_simple,
    biosmem_save_cmdline_sizes, biosmem_find_boot_data_update,
    biosmem_find_boot_data, biosmem_setup_allocator): Likewise.
    (biosmem_bootstrap_common): New function.
    (biosmem_xen_bootstrap): Likewise, for Xen.
    (biosmem_bootalloc): Perform bottom-up allocations for Xen.
    * i386/i386at/biosmem.h (biosmem_xen_bootstrap): New prototype, for Xen.
    * i386/i386at/model_dep.c (i386at_init): Call biosmem_xen_bootstrap instead
    of biosmem_bootstrap on Xen.
    * i386/include/mach/i386/vm_types.h (phys_addr_t): Define as an unsigned
    64-bits integer when PAE is enabled.
