[PATCH v3 0/3] Enable -cpu <cpu>,help

[Dinah Baum]

This patch adds the ability to query for CPU
features. Currently it is limited to the architecture that
support feature probing (arm, i386, and s390x).

Ex:
athlon features:
  3dnow=<qbool>
  3dnowext=<qbool>
  3dnowprefetch=<qbool>
  ...

  qapi: Moved architecture agnostic data types to `machine`
  qapi, target/: Enable 'query-cpu-model-expansion' on all architectures
  cpu, softmmu/vl.c: Change parsing of -cpu argument to allow -cpu
    cpu,help to print options for the CPU type similar to how the
    '-device' option works.
