Work on issue #4518815: Compatibility mode introduces compatibility regression...

...for Market App iRunner

There were a lot of serious issues with how we updated (or often didn't update)
the display and resource state when switching compatibility mode in conjunction
with restarting and updating application components.  This addresses everything
I could find.

Unfortunately it does *not* fix this particular app.  I am starting to think this
is just an issue in the app.  This change does fix a number of other problems
I could repro, such as switching the compatibility mode of an IME.

Also a few changes here and there to get rid of $#*&^!! debug logs.
