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.

fgets(3) returns a pointer, so compare against NULL, not integer 0.

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.

o Move NTOHL() and associated macros into <sys/param.h>. These are
deprecated in favor of the POSIX-defined lowercase variants.
o Change all occurrences of NTOHL() and associated marcros in the

o Add missing license bits to sparc64's <machine/endian.h>.

o Clean up <machine/endian.h> files.
o Remove unused __uint16_swap_uint32() from i386's <machine/endian.h>.
o Remove prototypes for non-existent bswapXX() functions.
o Include <machine/endian.h> in <arpa/inet.h> to define the
POSIX-required ntohl() family of functions.
o Do similar things to expose the ntohl() family in libstand, <netinet/in.h>,
and <sys/param.h>.
o Prepend underscores to the ntohl() family to help deal with
complexities associated with having MD (asm and inline) versions, and
having to prevent exposure of these functions in other headers that
happen to make use of endian-specific defines.
o Create weak aliases to the canonical function name to help deal with
third-party software forgetting to include an appropriate header.
o Remove some now unneeded pollution from <sys/types.h>.
o Add missing <arpa/inet.h> includes in userland.

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.

Set BINOWN=root explicitly for setuid root binaries.

This is not "useless", as one may have non-default
setting for BINOWN in make.conf, and we still want
these to be installed setuid root in this case.

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.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

Remove whitespace at EOL.

mdoc(7) police: removed HISTORY info from the .Os call.

Patches from OpenBSD:

- use strlcpy's instead of strcpy's
- & handle short packets properly.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The Id line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Remove useless `BINOWN=root' now that it is the default.

Make all strings representing hostnames to be NUL-terminated within
MAXHOSTNAMELEN chars, like everywhere else in the system, so that strcpy()s
and printf()s won't fail.
