There are two categories of preferences:
1. That are part of the default shared preference
   They were all getting backed up and restored.
   Added a blacklist to not restore some of these.
   e.g. current account

2. That are in a non-default shared preference file.
   These are not getting backed up currently, but added a specific
   local preference file for all such preferences.

Move java code to a different directory so that the unbundled
version doesn't try to compile the native code again.

the change to logging to remove any private dependencies and use
broadcast intents to VoiceSearch instead.

I have audited this code and it appears good to go for open-source,
but would appreciate a second pair of eyes.

Still to do after submitting this CL:

* Reintroduce Amith's memory leak fix (37557) which was the only CL
  added to LatinIME since the last merge over to the private copy.
* Make some changes to allow LatinIME to work without voice search
  installed. Currently I believe it will show the mic but fail if
  you press it. We need to base the visibility on the mic on the
  availability of the service.
* Fix this code to use the new Gservices framework, it's still trying
  to use the old one.

Backup the shared preferences when they change.
