Remove the resetting of the policy from this point in the test case
since the new default policy has the '__UNLABELED__' label, which is
not expected in subsequent checks.

This provides support for building the new merged qemu from
qemu-xen.git, or from a local checkout.
The default is still to use the in-tree version, because the patchman
infrastructure for testing, and propagation from staging to
xen-unstable, needs a small amount of work to cope with git.

My testing shows, for some smp guests, ent->fields.mask will not be
unmasked when hvm_dpci_eoi() is invoked at the first time. In that
case, we should rely on timeout call back to do pirq_guest_eoi() and
should not stop the per-irq timer too early.

It's not a sensible thing to do, and it is easier than auditing all
state save/restore functions for safety (most importantly, racing
against domain_relinquish_resources).
Also place a spin_barrier on domain_lock after asserting d->is_dying,
allowing critical regions under the domain_lock to safely check
is_dying and avoid races with domain_relinquish_resources().

Provide emulation for all FPU instructions except fsave/frstore &
fnstenv/fldenv.
While the main purpose of the patch is to avoid current and future
"gotchas" on FPU intructions used by various OS boot-loaders, it is
complete enough to run DOS realmode FPU applications and benchmarks,
but don't expect to set any speed records.

tapdisk, part of blktap, links against libcrypto. tapdisk includes
GPLv2 (tapaio.c) and other licensed code (block-qcow.c). The license
of OpenSSL is considered incompatible with the GPL by many
people. This patch changes them to link against libgcrypt, which is
LGPL.

hypervisor about memory changes.
The impact on disk performance is typically making it from 71.5MBps
down to 70.5Mbps during the live migration. The impact on network
performance is actually even hard to measure.

When suspend to S3, stop the cpufreq dbs governor. When resume from
S3, firstly sync cpu state and freq at the 1st dbs timer; from 2nd dbs
timer on, cpufreq dbs governor control cpu px transfer according to
its workload algorithm. Px statistic is also handled.

Rework blkdev_name_to_number to allow the tools to attach xvd disks
beyond xvdp.
1. Adds the handling for the /dev/xvd[q-z] and /dev/xvd[a-i][a-z]
extended devices
2. Changes blkdev_name_to_number() to return a tuple of (xenbus,
devnum), and then deals with the resulting fallout.

Through recent additions to the rombios the code section of the post
function has filled up considerably. When I enable the BX_TCGBIOS
compile time option the BIOS crashes since the post section code
(starts at $e05b) spills over into the nmi entry point (starts at
$e2c3). as86 doesn't cause an error when building.

When ir_ctrl->iremap_index == -1, it means there is no remap
