Requested by: Harlan Stenn <Harlan.Stenn@pfcs.com>

Accept SIGHUP as a "re-open logfile" signal.  As ppp
doesn't set it's serial line to it's controlling terminal,
we can use HUP :)

This is a candidate for 2.2.  The log.[ch] changes won't
conflict, but the main.c changes will.  We just want to change the
kill(...,SIGHUP) to a SIGTERM and change the signal(SIGHUP,Hangup)
to a pending_signal(SIGHUP,LogReOpen).
