to give them a larger timeslot to do that.
Requested by deraadt@ and various people on icb or vocally.

a.out stuff in link_aout.h and ELF stuff in link_elf.h.
Switch sparc64 back to MI link.h.
drahn@ ok (powerpc will switch soon).

millert@ ok

(this will warn if they are used without a terminating NULL pointer.
Note *pointer*, very useful for arches where 0 != (void *)0, in size)
okay millert@

decriptor -> descriptor
authentciated -> authenticated
transmition -> transmission

deraadt@ ok.

nobody.  While I do not like running things as nobody since the step
up is very small, we use this for other daemons in inetd.  And it is
still a small step.

From Dries Schellekens

active before /etc/pf.conf is loaded, just in case loading fails (and
leaves the inital set active). ok deraadt@

We could use skeyinfo(1) to check but this is much cheaper.

XXX libraries should not use atexit(3) from within, as program can terminate
with _exit.

suggested by deraadt@.

Tested by various people on various platforms, I'm willing to fix any
breakage this causes.
ok niels@ deraadt@ and mickey@ (after his comments were applied)

From Andr� Lucas <andre@ae-35.com>, fixes pr # 2658.
'Looks good' from miod@, millert@, and krw@.

where each user gets their own file, which is owned by that user.
An old S/Key database may be converted by running "skeyinit -C" as root.
Programs that need to access the S/Key database no longer need to be
setuid root.  They must now be setgid auth instead.

Job names are now "runtime.queue" where runtime is when the job will run
in Unix time format.  This is what SysV at does and allows us to nuke
the .SEQ file.
Historic BSD options for atq and atrm are now implemented;
atq and atrm get their own man pages.
At no longer does anything with the -v flag.  We print the execution
time when jobs are submitted so there is no need.
Most *scanf() usage is gone (one remains in atrun).
Better sanity checks in atrun.
Random style/cleanup.
With these changes we have the best of both worlds; POSIX compliance with
the traditional BSD features.

Also fix a typo; adapted from a patch by Moritz Jodeit
