This is the first RFC5424 (only) support for for logging to a remote
host. The syntax continues to follow the FreeBSD logger.

Turns out that gettimeofday() can return EOVERFLOW on systems with
32-bit time_t. This occurs when the UNIX Epoch wraps around, the
exact time is 03:14:07 UTC on 19 January 2038.
EOVERFLOW is not documented in gettimeofday(2), but instead of messing
up the entire syslog message -- causing syslogd to drop it -- we can
handle the overflow by falling back to time(NULL) (returning seconds
since start of Epoch) and rely on syslogd to, in turn, handle the
wraparound gracefully.

This patch merges the upstream NetBSD syslog.[ch], which adds syslogp()
family of APIs to support RFC5424. This API will first go into use in
the logger tool, klogd, and syslog_tst, then it will also be exposed
as libsyslog and syslog/syslog.h for end-users.

When a user links with syslog.c, or the future libsyslog, they may still
use the standard GLIBC header files. GLIBC redirects syslog() to the
__syslog_chk() definition early on, but a user may not notice when a
simple non-optimized (-O0 or none) program is compiled.
This currently does not affect musl libc.

From upstream FreeBSD Subversion r165903:
"Per Regents of the University of Calfornia letter,
remove advertising clause."
This patch also includes the renumbering of the clauses, making
this codebase truly 3-clause BSD licensed.
