MP3Extractor and MP3 decoder fixes - DO NOT MERGE
cherry-picked the following patches from HC branch:
o PV's mp3 decoder mistreated inputBufferCurrentLength in unit of bytes as in unit of bits
o Do not enforce the rule in MP3Extractor that all audio frames in an mp3 file must have the same mode
o When the temp buffer wraps around, the next read position should start
from what have been read to avoid reading the same remaining bytes in
the buffer again.
o Speed up MP3Extractor using cached reads
