looks all like a good idea, but I really have to insist that the commit
message explain everything in detail. Give a reason why the code is
similar or the same and why this makes sense.
Also splitting these into two or more patches makes sense. One adding
the stream receive and the other modifying L2CAP and RFCOMM to use it.
Agreed.

This makes my brain hurt. Please lets do this readable and with proper
coding style and/or a helper function.
That's unchanged code from rfcomm_sock_data_wait() in rfcomm/sock.c -
but I'll go ahead and break it up using multiple 'if' statements.
