the "splittability" of the keyboard.

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.
