[v2,0/4] python/qemu: New accel module and improvements

Message

On commit abf0bf998dcb John Snow moved some code out of __init__.py
to machine.py. kvm_available() remained in though. So on patch 01
I continue his work by creating a home for that method (the new
'accel' module). Honestly I was unsure about whether move the code
to any existing module or make a new, but since I am adding more
methods related with accelerators then I thought they would deserve a module.

The patches 02-04 introduce new helpers and make improvements. Later
I intend to use those methods on the acceptance tests such as
to automatically set the accelerator in QEMUMachine VM via Avocado
tags, and skip the test if the accelerator is not available.

Changes v1 -> v2:
- Removed 'Based on qmp.py' from python/qemu/accel.py
  (patch 01) [alex.bennee]
- logging added only when used on python/qemu/accel.py
  (patch 02) [alex.bennee]
