CPUID's replies are now pre-calculated in libxc and given to the
hypervisor via a new domctl.
There are two parts to this feature:
- We can overwrite cpuid's replies.
- We can check that a vm is compatible with a host's processor.

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.

- Move PAGE_SIZE and STACK_SIZE into __PAGE_SIZE and __STACK_SIZE in
arch_limits.h so as to permit getting them from there without
pulling all the internal Mini-OS defines.
- Setup a xen-elf cross-compilation environment in stubdom/cross-root
- Add a POSIX layer on top of Mini-OS by linking against the newlib C
library and lwIP, and implementing the Unixish part in mini-os/lib/sys.c
- Cross-compile zlib and libpci too.
- Add an xs.h-compatible layer on top of Mini-OS' xenbus.
- Cross-compile libxc with an additional xc_minios.c and a few things
disabled.
- Cross-compile ioemu with an additional block-vbd, but without sound,
tpm and other details. A few hacks are needed:
- Align ide and scsi buffers at least on sector size to permit
direct transmission to the block backend. While we are at it, just
page-align it to possibly save a segment. Also, limit the scsi
buffer size because of limitations of the block paravirtualization
protocol.
- Allocate big tables dynamically rather that letting them go to
bss: when Mini-OS gets installed in memory, bss is not lazily
allocated, and doing so during Mini-OS is unnecessarily trick while
we can simply use malloc.
- Had to change the Mini-OS compilation somehow, so as to export
Mini-OS compilation flags to the Makefiles of libxc and ioemu.

Preference seems to be to update library versions only when the ABI
changes. Only libxenctrl/libxenguest have their version number changed
to 3.2.0, as a reminder that they change on pretty much every major
release.
libfsimage/libxenstore/libblktap have not changed substantially
recently, hence the ABI has not changed, and version number stays the
same as in Xen 3.1 (and before).

* Arrange for the sonames of libxenstore, libxc, libfsimage and
libblktap to be set from a single place in Config.mk.
* Bumps the soname major version number to 3.2 in preparation for
3.2 rc1 after which we do not expect to have ABI changes.
I have not done anything about libaio and libflask. The former is
imported from elsewhere and if we're lucky will have sane versioning
upstream.
libflask has a very small interface and I'm hoping that the XSM
authors have been keeping some ABI discipline.

Use the guest's own p2m table instead of xc_get_pfn_list(), which
cannot handle PFNs with no MFN.
Dump a zeroed page for PFNs with no MFN.
Clearly deprecate xc_get_pfn_list().
Do not include a P2M table with HVM domains.
Refuse to dump HVM until we can map its pages with PFNs.

The idea is that this file is where we will have two implementations
of 'suspend cancellation': one which the guest is aware of (and is
faster) and the other which does more work to avoid requiring guest
modifications.
