Rusty Russell 35e3c1866e common: generalize extract_channel_id(). 
connectd is going to end up using this do demux; make it fast and complete.

Fixing this reveals a problem in openingd: it now extracts the channel_id
from funding_signed (which is where we transition off the temporary), and
gets upset.  So fix that.
