Expose hooks for more efficient log handling in Android apps.

This change introduces a new interface, DalvikLogHandler. Log
handlers that implement it opt-in to more efficient log handling
for common-case log messages. The API requires far fewer objects
to be allocated to log a message.

A related change in frameworks/base adopts this optimization
in the built-in AndroidHandler.

This optimization resulted in a 2.75x improvement on my device:
from 154ns to 56ns per message.
