Update to work with input server

Change-Id: I0bdcba5ad1f6b37a2991fae29e6b08bf023220c2
Add Android.mk and launch script for in-tree build

Android.mk uses the local copy of netty instead of the one that the
input server provides. The Netty 4 API hadn't stabilized for the pre-
release version of the lib that the input server includes. We can't
update that copy to final though since the inputer server and the two
pre-existing handlers use classes that were removed in 4 final.

Forward BYE messages to fbstream

Also clears out the send and receive queues on starts and stops
just to be safe. Sometimes some leftover messages were hanging around
from previous sessions and causing chaos in the next cycle.
