Use this in various places where it should serve no purpose to deliver
both broadcasts. This is intended to reduce somewhat the flurry of
broadcasts that we churn through during boot.
We can now locate event log tag definitions in individual packages
(and java constants for the tag numbers get auto-generated), so move
all the tags used by the system server into the package.
- Ensure system IMEs are put on the enabled list at startup/install.
- If the default IME is not installed, choose another one whenever building input method list.
This makes the system a little more careful to not start third party
code until it is ready to.
Also fix a little bug in SyncManager that would cause it to crash
during boot if sync was in a failure state.
