This allows increasing the rx queue size up to 1024: unlike with tx,
guests don't put in huge S/G lists into RX so the risk of running into
the max 1024 limitation due to some off-by-one seems small.
It's helpful for users like OVS-DPDK which don't do any buffering on the
host - 1K roughly matches 500 entries in tun + 256 in the current rx
queue, which seems to work reasonably well. We could probably make do
with ~750 entries but virtio spec limits us to powers of two.
It might be a good idea to specify an s/g size limit in a future
version.
It also might be possible to make the queue size smaller down the road, 64
seems like the minimal value which will still work (as guests seem to
assume a queue full of 1.5K buffers is enough to process the largest
incoming packet, which is ~64K). No one actually asked for this, and
with virtio 1 guests can reduce ring size without need for host
configuration, so don't bother with this for now.

This pull request supersedes ppc-for-2.8-20160922. There was a clang

Included in this set of ppc and spapr patches are:
* TCG implementations for more POWER9 instructions
* Some preliminary XICS fixes in preparataion for the pnv machine type
* A significant ADB (Macintosh kbd/mouse) cleanup
* Some conversions to use trace instead of debug macros
* Fixes to correctly handle global TLB flush synchronization in
TCG. This is already a bug, but it will have much more impact
when we get MTTCG
* Add more qtest testcases for Power
* Some MAINTAINERS updates
* Assorted bugfixes
* Add the basics of NUMA associativity to the spapr PCI host bridge
This touches some test files and monitor.c which are technically
outside the ppc code, but coming through this tree because the changes
are primarily of interest to ppc.

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

although the sed script in that patch no longer applies due to
other changes in the tree since then, and I also did some manual
cleanups (such as fixing whitespace to keep checkpatch happy).
