97c107262c Simplify, syslogd unconditionally includes fcntl.h already
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.

1a09654e79 Add logger tool from Finit project to complement sysklogd
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.

290c11d0d9 Sync. BSD license change with FreeBSD upstream
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.

301081604a Add RFC5424 support for remote syslog servers
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.

234cd4e669 Add required feature flags for when building with -std=c11
These feature flags are required to build with modern GCC that default
to newser C standard.  However, we should never enforce a standard on
the user -- there are far too many old/embedded systems out there with
very old toolchains that just want bug fixes and minor features for an
otherwise stable system.
