Brian Somers b7c5748e5e o Rename datalinks as soon as the name has been received so that
LQM and HDLC timer diagnostics come out with the correct name.
o Don't send an LQR immediately upon reviving a datalink.  Leave
  it 'till the next timeout.
o Add the link name to some more LQR diagnostics.
o Break out of the main loop when a descriptor exception is seen
  in select().
o Remove the evil nointr_[u]sleep() functions.  Timers should be
  (and are) used instead.
o Treat a read() of 0 bytes as an error that's fatal to the link
  on which the read() is done.  We should never read() 0 after
  select() says there's something there - not unless the link
  has been closed by the other side.
o Write the data seen before a HDLC header to the terminal in
  `term' mode, *not* back to the modem :-/
o Initialise our transmitted file descriptor before starting any
  timers.
o Only send data links that have *no* pending output data.  This
  means that our final ACK will be written rather than being
  nuked with the datalink transmission.
