input: fix race condition

frameencoder: fix for error in VPS when AccessUnitDelimeter is turned on

The bitstream needs to be reset before start encode VPS, since if AU_Delimeter
is turned on, there is one byte of data left in the bitstream that will be
written wrongly into the VPS.
TComDataCU: remove warnings for shadowed declaration
rc: accumulate mv bits, coeff bits per frame
encoder: RDOQ is only applicable at rd levels 4, 5, and 6
