Emacs is by default fooled into defaulting to conf-file-mode for
syslog.conf.5, so we add hinting to all man pages for consistency.

The '-n' option is commonly used for remote servers, so let's
consolidate the log rotation under the '-r' flag instead, with
the same syntax as previously established in syslog.conf

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.

- Add empty lines for readability, after return before new statement and
after variable declarations
- Remove explicit typecasting, NULL is NULL regardless of type
- Remove unnecessary braces and else

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.

The -fomit-frame-pointer is part of the standard optimization flags in
-O1 and above, so no need to enable it explicitly.

- Let syslog_tst.c use local syslog.c API, for wrapping
- Add -DTESTING to build of syslog_tst & C:o
- Enable CLOEXEC on each opened log file in syslog.c
- Simplify code for readability

For compatibility with GLIBC <2.19 we only need to define _BSD_SOURCE,
and for compatibility with GLIBC >=2.19 we must defined _DEFAULT_SOURCE.

On modern systems, both *BSD and Linux using GLIBC/musl, the signal's
disposition is not reset to SIG_DFL on invocation of its handler. On
Linux this is true because GLIBC/musl wraps signal() in sigaction()
with the same semantics as BSD.
A follow-up commit will refactor to use sigaction().

We always want to build with support for UNIX domain socket and remote
syslog (both receive and send). We can safely state that all systems
we aim to target supports FHS.
Also, start clean up gratuitous use of SYSV #ifdefs.

No need to check for SYSV (?) to include fcntl.h since syslogd.c already
includes it unconditionally. If this turns out to be an actual problem
we should probe for fcntl.h in configure and use #ifdef HAVE_FCNTL_H.

This patch introduces a relicensed logit from the Finit[1] project. It
has been rebranded as logger to complement the features implemented in
the sysklogd project.
Note, logger conflicts with the tool of the same name from util-linux.

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.

This patch adds support for sending in RFC5424[1] style format to remote
log servers. Section 6.5[2] lists some examples, here's one:
<30>1 2019-10-12T18:21:01.123456+02:00 troglobit finit 321 - - Starting service 'firewalld:1'
Note, sysklogd currently does not support MSGID and structured data, see
the RFC for more information on this.
