Add a fallback using glib g_test_add_vtable() internal function, whose

ppc patch queue for 2016-Sep-7

This is my first pull request for the newly opened qemu-2.8 tree.  It
contains a heap of things that were too late for 2.7 and have been
queued for a while.  In particular:
    * A number of preliminary patches for the powernv machine type
        * A substantial cleanup of exception handling which will be
          necessary to support running a TCG with hypervisor
          facilities
    * A start on support for POWER9
        * Some TCG implementations for new POWER9 instructions
        * Some TCG and related cleanups in preparation for POWER9
    * Some assorted TCG optimizations
    * An implementation of the H_CHANGE_LOGICAL_LAN_MAC hypercall
      which allows the MAC address to be changed on the PAPR virtual
      NIC.
    * Add some extra test cases for several machines (this isn't
      strictly in the ppc code, but is most value to ppc)

NOTE: This pull request supersedes ppc-for-2.8-20160906, which had
some problems.  Changes:
  * Dropped BenH's lmw/stmw speedups, which break for
    qemu-system-ppc64 on BE hosts
  * A small fix to Thomas' serial output test to avoid a warning on
    the isapc machine type.
  * Some trivial checkpatch fixes

Note that some of the patches in this series still have large numbers
of checkpatch warnings.  This is because they're moving existing code
that predates most of the checkpatch style conventions.

Some of the machines that we have got a firmware image for write
some output to the serial console while booting up. We can use
this output to make sure that the machine is basically working,
so this adds a test that checks the output of these machines
for some well-known "magic" strings.

The rather random list of check-qtest-xxx entries caused some
confusion in the past, where to use "=" and where to use "+="
(see commits 0ccac16f and 1f5c1cfb
for example).
Sorting the check-qtest-xxx entries by architecure instead and
using some empty lines inbetween should help to ease this
situation a little bit, so that it is hopefully now obvious
that new tests should be added with "+=" instead of "=".
While we are at it, this patch also comments out two of the
"gcov-files-..." lines since the corresponding m48t59-test is
disabled for sparc and sparc64, too.

The current mapping, while correct for the base ports (which is all the
driver uses these days), is wrong for the extended registers.

I suspect the bugs come from incorrect tables in the CHRP IO Ref document,
I have verified the new values here match Apple's MacTech.pdf.

Note: Nothing that I know of actually uses these registers so it's not a
huge deal, but this patch has the added advantage of adding comments to
document what the registers are.
