This patch factors out a lot of the basic protocol code: sending OKAY,
sending FAIL, and sending a length-prefixed string.
ADB_TRACE has been non-optional for a long time, so let's just remove
the #ifs.
Also actually build the device tracker test tool (and remove its duplicate).
Bug: http://b/20666660
