AndroidBufferQueue:
 - errors found by setItems are now hard errors, and cause Enqueue to
   return an error result (e.g. PARAMETER_INVALID or PRECONDITIONS_VIOLATED)
 - disallow EOS with non-zero data
 - disallow Enqueue after EOS
 - Enqueue checks MPEG-2 sync byte of first packet to reduce chance of downstream failures
 - use MPEG-2 terminology "packet" instead of "block"
 - Clear and init don't need to erase buffer content, as it is inaccessible
 - put placeholder in IAndroidBufferQueue_SetCallbackEventsMask
   for additional events beyond SL_ANDROIDBUFFERQUEUEEVENT_PROCESSED
 - comment unused field mBufferState in AdvancedBufferHeader
 - fix a minor typo
 - add dump method, #if 0 out by default
