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.

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.

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.
