optimizing mpeg4_encode_block(), generates allso slightly shorter bitstream as some codes can be represented as esc1 and esc2 and esc2 is shorter for a few of them

support decoding of the last mpeg "packet" even if no startcode is immedeatly afterwards (fixes bugs with mpeg in avi)
new behavior is only activated if CODEC_FLAG_NOT_TRUNCATED is set
