Eliminate redundant ones, fix names (where so far inappropriately
referring to capability structure fields the don't really relate to),
use symbolic names instead of raw numbers, and remove an unusable one.
No functional change intended.

This matches similar checks done in Linux, since no good can come from
a domain trying to enable both MSI and MSI-X on the same device at the
same time.

This includes replacing the bogus definition of cpumask_test_cpu()
(introduced by c/s 20073) with a Linux compatible one and replacing
the bad uses with cpu_isset().

Xen absolute system time, so that it can use SCHEDOP_poll in a
sensible fashion. HVM PV drivers can't use the normal PV clock
because they might have TSC offsets that hey don't know about.

The former strips dom0 of its usual 1:1 mapping of all memory, and
only provides it with mappings of its own memory, like any other
domain. The latter is a new consistent name for iommu=passthrough.

Currently "make stubdom" on its own fails because it depends on files
being installed by the results of "make tools". This also means that
in some circumstances a parallel "make tools stubdom" (or "make all")
can fail due to races. So make "make stubdom" depend on "make tools"
having completed first.

The hardware CPUID-levelling features level the feature flags but
don't change the CPU family/model/stepping. Relax the HVM restore
check on family/model/stepping to printk but not veto the load, so
that VMs can be migrated between machines that have been
CPUID-levelled.

Allow HVM save/restore from different changesets of Xen. The HVM save
records are supposed to be backwards compatible; XenServer
live-migrates between versions of Xen during upgrades.

Otherwise vcpu_periodic_timer_work() can think the next timer is in
the future (and re-issue it unchanged) while timer_softirq_action()
thinks it's in the past (and fires it immediately), leading to
livelock.

This relies on the previous fix to let DS != SS

Implement parsing for timer_mode, hpet and vpt_align parameters.
These are all HVM only parameters and hpet/vpt_align are boolean so
change types and place in hvm union accordingly. Also HPET is x86 only
on principle so make this compile-time conditional on arch as-is
viridian.

The OCaml xenstored supports the XS_RESTRICT operation, which
deprivileges a dom0 xenstore connection so it can only affect one
domain's entries. Add the relevant definitions to the C libraries
so that callers can use it.
