Fix TCPS_HAVERCVDFIN() to actually catch all TCP states in which a FIN
has been received (CLOSE_WAIT, CLOSING, LAST_ACK, and TIME_WAIT).

PR#5696 + nroff fixes and text clarity
PR#5697 + nroff cleanup
macppc ramdisk tools.
Add another sound card.
KNF, and use MOUNT_FFS over "ffs"
KNF.
Add nvram device support.
clean up a bit of cruft.
KNF.
- use S_IWGRP over 020
- KNF
- ensure we don't overflow a buffer (don't think it would anyway).
- favour snprintf over sprintf (and varargs versions)
nvram support.
Add powerpc and macppc files.
Make halt and reboot wait up to 32 seconds after kill(-1, SIGTERM), but
check at 3 second intervals if any are left.
This will help slow machines to cleanly shut down X servers (to make the
console visible), databases, or Usenet news servers.
Fix bugs found in scrolling, make scrolling never leave blank
lines in the menu.
check return value of kvm_read() more safe
- deal with fork failure better
- some more KNF nits
- no more "union wait"
Make this a bit less fork-happy.
Further redux.
- KNF.
- check return call of several important system calls
- clean up some more cruft.
- support "uucpd -l" for extra (syslog(3)) logging.
- add a man page for uucpd.  did it really arrive in 4.2BSD as the code
  indicates?  that's what `HISTORY' says...
