Initialize the group list so that any filter programs that are
run by lpd are not run with root's groups.

The other day someone brought me an old Apple Laserwriter II with a serial
interface set at 57600 baud, and I found out the hard way that lpd doesn't
know about speeds greater than 38400, even though <sys/ttydev.h> also
permits 57600 and 115200 baud. Fix this by adding B57600 and B115200 to the
'bauds' table. (The Apple printer worked properly once I did this, BTW. :)

Remove trailing whitespace.

Close PR:
>Number: 368
>Category: bin
>Synopsis: Lpd doesn't log errors after failed exec
>Description:

If an exec done by lpd fails, nothing is sent to the system log
indicating what went wrong. This is because lpd closes all of
the file descriptors before doing the exec, thus closing the syslog
file descriptor in the process.

Use the "-F" option to /bin/pr now that we have it (thanks to Posix).
This helps for printers that tend to get out of sync. (For the
cautious folks: we used to have it in 1.1.5, too. But GNU pr used
"-f" for it.)

Wrong description where the printer socket lives. Changed from /dev/printer
to /var/run/printer. Bug report submitted by Ollivier ROBERT.

Get rid of update. Make man page installation work with our scheme
(and rename a few in the process).
