Remove large multistream stack buffers.
This avoids allocating any buffers on the stack that depend on the
total channel count.
Such buffers could easily exceed the size of the
NONTHREADSAFE_PSEUDOSTACK.
It also checks the frame_size argument in both the encoder and
decoder to avoid allocating large stack buffers for opus_encode()
calls that would fail anyway or opus_decode() calls that would
never use all that space anyway.
