[PATCH 0/9] Add executable_changed event to Python API

[Andrew Burgess <aburgess@redhat.com>]

When I started, I thought this would be trivial; I wanted to expose
the executable_changed observer through the Python API.

Well, it turns out that the executable filename isn't directly visible
from the Python API, so having an event for when it changes doesn't
make a great deal of sense.  So the first 3 patches sort that out.

Then, once I started looking at how the executable_changed observer is
used, it feels like it is currently overloaded a little, and, as a
result, triggers more than it needs to.  The next 3 patches try to
sort this out.

Then patch 7 adds some additional arguments to the executable changed
observer.

Patch 8 is the trivial patch that exposes the observer as an event in
the Python API.

.... And patch 9 fixes a final bug/annoyance which I ran into while
writing the tests for patch 8.
