Change old-style function definition

Rework all non-contributed files that use `struct timezone'.

This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:

int gettimeofday(struct timeval *restrict tp, void *restrict tzp);

Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.

While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

Some people pointed out long is 32-bit on some arches, while time_t is
64-bit, so better cast time_t to intmax_t, and use the appropriate
printf format strings.

In usr.sbin/timed, fix several issues with printf formats:
- Cast time_t's to long, and print them with %ld.
- Print ptrdiff_t's with %td.
- Print ssize_t's and size_t's with %zd and %zu.
- Print int32_t's with %d.
Also, replace some int variables with the more appropriate size_t.

Simplify inclusion of the tsptype array a bit.

We don't need this array in timed.c -- only readmsg.c.

Remove the advertising clause from UCB copyrighted files in usr.sbin. This
is in accordance with the information provided at

Unifdef all the SGI code. It mainly added clutter while providing some
specialized logging, SGI-specific priority massaging, and SCI-specific
time trimming support. Also add missing $FreeBSD$'s.

Inspired by: NetBSD

The timed protocol is not implemented in a compatible way by all vendors;
the size of the tsp_name field is OS-dependent. 4.3BSD used a 32-byte
field, FreeBSD uses MAXHOSTNAMELEN and RedHat apparently uses a 64-byte
field. As a result, sanity checking code added a few months ago to detect
short packets will fail when interoperating with one of these other vendors.

Change the short packet detection code to expect a minimum packet size
corresponding to the 4.3BSD implementation, which should be a safe minimum
size.

Check that the hostname field in received packets is NUL-terminated.

* Fix a segfault when timed(8) receives a packet with a bad tsp_type.
* Check that received packets aren't too short, as this could cause other
problems.

Don't assume that time_t is long.
