Page offline support in Xen side
This patch add support to offline a page. The basical idea is, when a
page is assigned, it will be marked offline pending and be moved out of
buddy when freed, when a page is free, it will be moved out of buddy directly.
One notice after this change is, now the page->count_info is not
always 0, especially for shadow page, since the PGC_offlining bit may be set.

txt: perform per-domain (and frametable and xenheap) MAC on entry into
S3 and verification on resume.
The MAC algorithm is called VMAC and was developed by Ted Krovetz and
Wei Dai (more details are in the files). It is based on a universal hash
function. The universal hash is passed through a pseudo-random function,
implemented using AES. More details can be found at
http://fastcrypto.org/vmac/. =
The AES code comes from the OpenBSD implementation (which is derived
from the implementation referenced in VMAC site).
As Xen does not have a good source of entropy to generate its own key
(for the keyed hash), it uses the key that tboot passes in.
Although the code attempts to MAC all of a domain's pages (code/data,
VT-d tables) based on its s3_integrity flag, some of a domain's memory may
always be MAC'ed, e.g. shadow page tables. Only xenheap pages that are in
use are MAC'ed. We believe that the memory MAC'ed by the Xen code and the
ranges passed to tboot to MAC cover all of the memory whose integrity needs
to be protected on S3. Any suggestions or ranges that we missed are
welcome.

passthrough: fix MSI-X table fixmap allocation
Currently, msix table pages are allocated a fixmap page per vector,
the available fixmap pages will be depleted when assigning devices
with large number of vectors. This patch fixes it, and a bug that
prevents cross-page MSI-X table from working properly
It now allocates msix table fixmap pages per device, if the table
entries of two msix vectors share the same page, it will only be
mapped to fixmap once. A ref count is maintained so that it can
be unmapped when all the vectors are freed.
Also changes the meaning of msi_desc->mask_base from the va of msix
table start to the va of the target entry. The former one is currently
buggy (it always maps the first page but msix can support up to 2048
entries) and can't handle separately allocated pages.
