[PATCH v3 0/3] python/machine.py: refactor shutdown

[John Snow]

v3:
 - Split _post_shutdown refactor into own patch (now 1/3)
 - Re-add sigkill warning squelch (now 3/3)

NOTE: I re-added the squelch in its own patch for review purposes, but
for the purposes of avoiding temporary breakage, a maintainer may wish
to squash patches 2 and 3 if they are accepted.

v2: Philippe took patches 1, 3 and 4.

This is a re-write of what was:
[PATCH RFC 03/32] python//machine.py: remove bare except
[PATCH 2/4] python/machine.py: remove bare except

It's a bit heavier handed, but it should address some of kwolf's
feedback from the RFC version.

Applies straight to origin/master, ought to pass pylint and flake8:

> cd ~/src/qemu/python/qemu
> pylint *.py
> flake8 *.py

John Snow (3):
  python/machine.py: consolidate _post_shutdown()
  python/machine.py: refactor shutdown
  python/machine.py: re-add sigkill warning suppression
