[IA64] Use ppn to store io type.
Instead of using 3 extra bits in pte to store the io type, only one bit
is used to mark the page as an IO page and the type is stored in the ppn
field. This both save 2 bits and allow many more io types.
Move the VTi memory map to arch-ia64/hvm/memmap.h

x86: Support loading Linux bzImage v2.08 and up.
The latest -mm kernel (2.6.25-rc3-mm1) contains v2.08 of the Linux
bzImage format which embeds an ELF file in place of the raw payload
allowing it to be extracted and used by the Xen domain builder.
It is expected that this functionality will be put forward for 2.6.26.

Revert all usages of gcc's __extension__ keyword, and instead assert
that our headers are not built with __GNUC__ and __STRICT_ANSI__.
__extension__ had some weird (and buggy) behaviours when nested which
make it a risky proposition for general usage in our header
files. Better to disallow -ansi, -std=c99, and similar gcc options
when building against Xen headers.

ioemu: actually check for errors in bdrv_flush et al
bdrv_flush is declared to return void, but this is wrong because it
means that the implementations have nowhere to report their errors.
Indeed, the implementations generally ignore errors.
This patch corrects this by making it return int (implicitly, either 0
or -errno, as for other similar functions). All of the
implementations and callers are adjusted too.

Clean up handling of IS_PRIV_FOR() and rcu_[un]lock_domain().
In particular this *removes* some IS_PRIV_FOR() checks. *Especially*
in particular, all domctls are executable only by dom0. Several of
them were really unsafe for execution by a stub domain as they can
affect global system resource usage.
This probably breaks stub domains. Where necessary, some of these
reversions can themselves be reverted where they are judged both
necessary and safe.
