Rebased and resent from about a month ago.

Since version 2.10, QEMU can be built without TCG. This patch
adds capabillity QEMU_CAPS_TCG_DISABLED that allows libvirt
to use a QEMU built without TCG.

Rather than create a capability that is set whenever TCG is
enabled (almost always), QEMU_CAPS_TCG_DISABLED is set only
when the TCG is not available. This avoids some issues
with backwards compatability.

For a domain that was created using QEMU >= 2.10 with KVM,
there is no information in the cached XML file that says
whether or not TCG was enabled. Versions of QEMU older
than 2.10 do not have a QMP interface for determining
whether QEMU is available. Since QEMU_CAPS_TCG_DISABLED
is set only when TCG is disabled, we do not have to do any
extra work to infer an appropriate value in either of these
cases.

QEMU_CAPS_TCG_DISABLED is set via QMP command qom-list-types.

Tobin Feldman-Fitzthum (5):
  add QEMU_CAPS_TCG_DISABLED and probe conditionally
  add virQEMUCapsGetVirtType convenience function
  add virQEMUCapsProbeQMPTCGState function to set QEMU_CAPS_TCG_DISABLED
  use new functions when probing
  Add second qom-list-types call to test data.
