VT-d: Fix ATS enabling for device assignment
Currently, Xen only enables ATS in Xen booting. When an ATS capable
device is assigned to guest, ATS is actually not enabled because FLR
before assignment causes it to be disabled. Thus ATS cannot be used in
guest. This patch enables ATS in domain_context_mapping. This ensures
ATS is enabled in assignment because FLR is earlier than
domain_context_mapping call. Therefore ATS can be used in guest. This
patch also implements disable_ats_device to disable ATS when the
device is deassigned from a domain.

xs: avoid pthread_join deadlock in xs_daemon_close
Doing a pthread_cancel and join on the reader thread while holding all
the request/reply/watch mutexes can deadlock if the thread needs to
take any of those mutexes to exit. Kill off the reader thread before
taking any mutexes (which should be redundant if we're
single-threaded at that point).

xs: make sure mutexes are cleaned up and memory freed if the read thread is cancelled
If the read thread is terminated with pthread cancel, it must make
sure all memory is freed and mutexes are unlocked.

Honour XEN_LINUX_GIT_LOCALBRANCH and XEN_LINUX_GITREV variables
XEN_GIT_ORIGIN to set the name of the remote origin; the default is
still "xen".
XEN_LINUX_GIT_LOCALBRANCH allows the name of the local branch to be
set. The default is the same as the remote branch.
XEN_LINUX_GITREV allows a specific GIT revision to be checked out,
rather than a branch. By default it is the remote branch name.
This change should result in no change in behaviour in the normal
case.

This dramatically simplifies our code while also avoiding compile

x86: TSC handling cleanups
"I am removing the tsc_scaled variable that is never actually used
because when tsc needs to be scaled vtsc is 1. I am also making this
more explicit in tsc_set_info. I am also removing hvm_domain.gtsc_khz
that is a duplicate of d->arch.tsc_khz. I am using scale_delta(delta,
&d->arch.ns_to_vtsc) to scale the tsc value before returning it to the
guest like in the pv case. I added a feature flag to specify that the
pvclock algorithm is safe to be used in an HVM guest so that the guest
can now use it without hanging."
