Update old-style definitions to ANSI, remove a couple of register
definitions along the way. Fixed gcc 4.1 build (thank you vax)

Remove clause 3 and 4 from TNF licenses

Delint.
Remove trailing ; from uses of __weak_alias(). The macro inserts this if
needed.

If port provides __weak_alias(), provide an Standard C and POSIX pure
identifier namespace by renaming non standard functions and variables
such that they have a leading underscore. The library will use those
names internally. Weak aliases are used to provide the original names
to the API.

This is only the first part of this change. It is most of the functions
which are implemented in C for all NetBSD ports. Subsequent changes are
to add the same support to the remaining C files, to assembly files, and
to the automagically generated assembly source used for system calls.
When all of the above is done, ports with weak alias support should add
a definition for __weak_alias to <sys/cdefs.h>.

__RCSID() police, typo in variable name; from jbernard@tater.mines.edu in
PR lib/3889.

Implement sleep() and usleep() in terms of nanosleep(). Uses only one
syscall instead of eight, and doesn't have any interactions with alarm
or interval timers.

Prototype sleephandler
Fix RCSID's

Make it correctly return unslept seconds if interrupted for any other
reason than SIGALRM. (Was ALWAYS returning 0.)

Slight simplification.

Eliminate race by stopping timer before restarting it with remaining time
(one more system call).

Eliminate race in the "normal" case of not being interrupted by another signal.

1) Turn off timer before resetting signal disposition.
2) Set signal mask before signal action, to avoid held SIGALRMs
bursting in after unsetting the handler.

Explicitly unblock SIGALRM while waiting.

Minor changes.

Update to use timer{add,sub}().

fix up some RCS Id's i botched.

merge with 4.4-Lite, keeping local changes. clean up Ids

Clean this up a little. No functional changes.

Changed to be POSIX.1 complian; now sleep can be interrupted, and it returns
the amount of time left "unslept" when it is.

Declare rcsid strings so they are stored in text segment.

Add even more RCS frobs.
