snprintf/vsnprintf return < 0 on error, rather than -1.

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

Use a constant format string and output the variable part with %s

ok krw@ millert@

Use O_CLOEXEC when opening fds local to a function

ok jca@ krw@

creat() -> open equiv; from Frederic Nowak

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

casts that cannot cause breakage in the future

spaces, and a off_t typecast to please lint

Make sure we check snprintf return value for failure or truncation before
using it. Make uu_lock_txfr work by properly checking return value from
put_pid(). Fix an FD leak on the lockfile in an error path (from FreeBSD
with modifications). OK millert@, input from otto@ and Bruno Rohee.

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

some -Wall and spaces cleanup, scsi.c left.
some brave soul should look at it.

pid_t cleanup

Part one of userland __P removal. Done with a simple regexp with some minor hand editing to make comments line up correctly. Another pass is forthcoming that handles the cases that could not be done automatically.

Add opendisk from NetBSD.

Add OpenBSD tags to files

More <sys/file.h> vs. <fcntl.h> and open() flags fixes.

Get the pid right if a stale lock file exists.
Submitted by: Lawrence D. Lopez <lopez@cisco.com>

Cast pid_t to int for sprintf.
Pointed out by: Charlie Sorsby <crs@hgo.net>

Add uu_lock_txfr() for donating locks to another process.

Correct the ftruncate() call.

Introduce uu_lock(), uu_unlock() and uu_lockerr()
into libutil.
