Fix domain shutdown so that the new status, and notification to domain0,
occur *after* the domain is fully descheduled and its execution state
synchronised.

Rename some of the pagetable access macros:
l?e_create_* -> l?e_from_*
*_phys -> *_paddr
*_value -> *_intpte
l?e_add_flags, l?e_remove_flags, l?e_has_changed now take ptes by value
rather than by reference.
The pagetable hypercalls are fixed to use l?e_from_intpte() rather than
abusing l?e_from_paddr(), which munged the NX bit incorrectly on x86/64.
Thanks to Scott Parish for spotting this one.

ioemu fixes: do not install into /usr/share/qemu as it conflicts with
real qemu installations. Also, do not link x86/64 with a special linker
script -- breaks on SLES9 and ought to be unnecessary.
The linker scripts and configuration/Makefile environment all need
stripping out at some point.

Subject: PAE support
This patch adds initial support for PAE paging to xen.
This patch does:
* boot Xen itself with PAE paging enabled.
* add PAE support to the dom0 domain builder.
Some notes on the design and the changes:
* There are two new config options: CONFIG_X86_PAE (boolean,
same name Linux uses to simply things) and
CONFIG_PAGING_LEVELS (int, possible values are 2,3,4). I've
used #if CONFIG_PAGING_LEVELS for stuff which simply depends
on the number of paging levels in the code common for
x86-32/64, and CONFIG_X86_PAE for special PAE quirks or
i386-only stuff. I've tried to avoid ifdefs if possible
though, often I rearranged code to make it work in both
PAE and non-PAE case instead.
* idle_pg_table: 3rd level is statically initialized, 2nd
level is contignous in physical and virtual memory, so it can
be addressed linear (the dom0 builder uses the same trick to
simplify things a bit btw.). There are two new symbols:
idle_pg_table_l3 and idle_pg_table_l2 for the two tables.
idle_pg_table is aliased to the toplevel page table, i.e.
idle_pg_table_l3 in PAE mode and idle_pg_table_l2 in non-pae
mode. The idle l3 table is actually never ever touched after
boot, the l2 table is accessed via idle_pg_table_l2 and
addressed linear in both PAE and non-PAE mode.
* I've added a "intpte_t" type and a PRIpte define, modeled
after the C99 inttypes.h header, for page table entries.

By default do not enable local APIC if disabled by the BIOS. This
matches Linux behaviour and ought to improve stability on buggy
hardware/firmware (laptops in particular). As in Linux, you can
forcibly enable the APIC with 'lapic' command-line option, or
forcibly ignore it with 'nolapic'.
