change debug level to a debug vector; add levels on logging (and the
-L flag); change logging to be by message-id; elevate message-id;
some lint-type cleanup

split off clock stuff from util.c so that vacation will compile

put timeouts on net reads

lint

call the routine putline to output lines to mailers. this lets us
implement line length limits, etc. for full SMTP compatibility.

pass lint. notice that definitions in llib-lc have changed for
alarm() and sleep() calls {arg was unsigned, is now int}.

add dfopen as a "determined fopen" -- it retries if it gets recoverable
errors. we use it for returning mail (to dead.letter) and creating the

add dfopen as a "determined fopen" -- it retries if it gets recoverable
errors. we use it for returning mail (to dead.letter) and creating the

take % as an acceptable name terminator in GECOS field
("in-care-of") -- for TEF%UCSFCGL

cleanup so it will go through lint without any fancy grep -v's;
change the way SCCS Id's are handled.

initial prep to put in Daemon mode

changes to work under a V6 system -- mostly compilation flags

break some configuration into conf.h -- simplifies makefile changes
on different machines. But there are still conditional libraries, so
this may not be a good idea.....

match on full name for local users

totally rework aliasing scheme -- sucks when no DBM now,
but works better for the usual case; fix some quoting problems
(and how many did I add?); remove .mailer feature since .forward
will simulate
