sbcparse's frame coalescing is broken for joint stereo SBC streams. We only
ever get frames from these streams out of sbcparse with one frame to a buffer.

There's a mistake in the SBC frame header size calculation (see the attached
patch for a full explanation) that was introduced in the rewrite of the bluez
code. Because of this, the frame coalescing code can't find the next frame
where it expects it to be, and it gives up on coalescing the frame with any
subsequent ones.
