917ef4ed1d Add support for include /etc/syslog.d/*.conf in /etc/syslog.conf
- Massive refactor of the .conf file parsing
- Add queue.h v1.43 from OpenBSD, has _SAFE versions unlike GLIBC queue.h
- Use queue.h list macros instead of homegrown linked list
- Adopt NetBSD reconf style; on failure to reload keep old config

48a9f1fdd7 Remove old TESTING mode, incl. tsyslogd and syslog-tst
This special build option enabled reading syslog messages from stdin on
syslogd.  It also disabled all other standard features of syslogd, which
made it a bit too far from the real thing.

A better approac is to start syslogd with -p /tmp/foo and let a test
application, e.g. logger -u /tmp/foo, connect using the standard UNIX
domain socket API.

f6e17bd6b3 Update syslog.c, add syslog.h from NetBSD to get new syslogp() API
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.

097d9efdbe Replace default optimization flag with -fno-strict-aliasing
The -fomit-frame-pointer is part of the standard optimization flags in
-O1 and above, so no need to enable it explicitly.

33411f8a0c Drop define of _SVID_SOURCE, not needed anymore
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.

f67ed6934a Simplify, remove #ifdefs for always defined paths
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.

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.

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.

slightly more flexible since you don't need to edit the Makefile.
