Replace the use of wall clock time with monotonically increasing
clock. In general, gettimeofday() is not appropriate interface
when accounting for elasped time because it can go backward, in
which case the policy code could errornously consider the limit
as exceeded.

Removed T/TCP bits.

Revert previous commit for now, which seems to have (re)introduced some
old bugs, as well as some unwanted side effects. I will do more
investigation and fix these issues first.

Improves and cleanups over inetd(8):

- Teach inetd(8) about kqueue, originally implemented by jmg@[1].

Kill __P, yuck.

Fix most of the warnings given by WARNS=2.

Give inetd the ability to manage unix domain sockets. Details of
how to use this feature are in the man page. This is based on work
by Lyndon Nerenberg.

(The only difficult part about this patch is the fact that you
can't fchown a unix domain socket, which means the sockets must be
put in a secure directory).

Get rid of se_ctladdrinitok, which doesn't do anything and seemes
to have been accidently imported when ipv6 support was added to
inetd.

This patch cleans up the ident stuff in inetd. The code which has
been patched so many times it was a bit of a mess. There are style,
code and man page cleanups. The following are the functional changes:

The RFC only permits the returning of 4 possible error
codes, make sure we only return these (PR 27636).

Use MAXLOGNAME to determine the longest usernames.

Add a -i flag, which returns the uid instead of the username
(this is from a PR 25787, which also contained alot of the
cleanups in this patch).

Various cleanups of inetd: Avoid shadowing variables, use socklen_t
instead of ints, don't cast to char *, clear up some remote name
handling code which had become a little odd.

Should result in no functional changes.

Tidy up some prototypes:
make sure there is exactly one prototype for each function,
use K&R style definitions everywhere to match dominant style,
make flag_signal take an int to avoid problems if we have
ANSI prototypes and K&R definitions.

Fix two typos in comments.

This commit encompasses the following changes to inetd:
1. Cleanups of ident_stream. "Evil" stdio is less used.
2. The BSD Copyright was added to the top of builtins.c.
3. As suggested, a timeout is now implemented in the ident
service. It defaults to 10 seconds. If enough people want
it, I'll make it configurable.

Suggested by: msmith

Move code for all builtin services from inetd.c to builtins.c, including
the Green Piece. :-)

In future, new builtin services are less likely to need to touch the
already tangled inetd.c .
