Maintain a `necessary' marker to indicate that we *probably*
need to process a signal (usually a SIGALRM). Check to see
if we need to process a signal both before *and* after calling
select() as older (pre-2.0) versions of ppp used to.
This handles the possibility that ppp may block at some
point (maybe due to an open() of a misconfigured device).
Previously, we'd potentially lock up in select().
The `necessary' marker reduces the increased signal checking
overhead so that at full speed with no compression transferring
an 83Mb file via a ``!ppp -direct'' device, we get a 1%
throughput gain.
