[speex-dev] speex_decode() doesn't empty buffer in u-wideband and quality 4

[Jean-Marc Valin]

Actually, the way it's done speex_bits_remaining() might return a
non-zero value if the number of bits in the stream is not a multiple of
8 (whole bytes). When you read the bytes, there's just no way to know
whether all of the bits in the last byte are used. The normal way to
know if you're at the end is to call speex_decode and look at the return
value. Otherwise, you'll need to check for number of bits remaining. If
it's < 5 bits, it's sure to be the end. Otherwise, you'll need to look
for a 01111 pattern (the terminator). speex_decode all does that for you
though.
