* Add flag to enable/disable timstamps for process log.
solves #2615
* Remove timestamp argument from log.Printf()
* Add log-timestamps=false to systemd unit
* Copy log flags
* Fix argument list
Clear rc_flags in start precmd. If these flags are still present during
start command, they are passed to daemon(8) instead of caddy(8).
Extract all options into $caddy_options environment variable.
In systemd 231
(4f10b80786/NEWS (L3558-L3565)),
ReadWriteDirectories was renamed ReadWritePaths.
In https://github.com/caddyserver/caddy/pull/2620/files, @aspeteRakete
renamed the directive in Caddy's example systemd unit.
However, this means that if anyone runs this sytemd unit on a version of
systemd older than 231, Caddy will go into a crash loop that hammers
Let's Encrypt's servers. That's because the ProtectSystem=full directive
prevents writes to all paths that aren't explicitly permitted, and older
systemd doesn't see any paths being permitted.
To maximize compatibility, I re-add the original ReadWriteDirectories
directive. Older systemd will read that; newer systemd will read the
newer directive. Both should ignore the directive they do not recognize.
Another approach to solve this problem would be to remove
ProtectSystem=true, originally introduced in da8ae9e5. That would reduce
the risk of similar breakages in the future. It would make for a slightly
less "exemplary" systemd unit, but I think it would still be adequate,
given that this unit runs caddy as "www-data", a user the presumably has
low privileges.
* Use syslog to manage caddy std{out,err} on FreeBSD
There is no good way to rotate the logfile created by the previous
FreeBSD rc.d script (it's the result of redirecting std{out,err} and
is held open by the shell).
This solves the problem by sending caddy's std{out,err} stream to
syslog, using the daemon command's builtin functionality.
It replaces the old `caddy_logfile` rc.conf variable with
`caddy_syslog_facility` (which defaults to 'local7') and
`caddy_syslog_level` (which defaults to 'notice').
By default, these messages will end up in /var/log/messages but can
be redirected as documented in the script's comments.
* Add info about rotating log with newsyslog
If you create a caddy specific logfile in `/var/log`, you should
rotate it.
This adds a bit of info to the dist/init/freebsd/README.md about
rotating that log file with newsyslog.
* Update README.md
I believe the owner and group of the `chown` command here are mixed up. As it was caused a permissions issue, with the service being unable to read the directory.

Revert changes back to the original suggested changes
The rc.subr framework already takes care of substituting user. So, using
daemon's -u option is double user-substitution and fails if $caddy_user
is non-root.
This change eliminates the `[ERROR] Could not write pidfile: open /var/run/caddy.pid: permission denied` from caddy.log.
The start-stop-daemon writes the file as root so the DAEMONUSER that caddy runs as cannot write to the .pid file.
