The fact that most of the daemon's state is stored on the stack
of the main() makes it hard to split the logic smaller chunks.
Which in turn leads to huge main func that does a a lot of things.
struct log_params existed because some variables need to be passed
into other functions together.
This change renames struct log_params into daemon_state
and moves the rest of the variables into it. This is a necessary
preparation step for further refactroing.

Now when supervsion mode has it's own variable there is really no
reason to set it separately from the rest of the variables. Move
initialization of supervise_enabled var to the argument processing
switch loop, where it belongs.

The 'restart' variable was responsible for enablement of restart
behavior and for restart delay. While it may seem convenient it
leads to cluttering the exit/restart logic

The default system log rotation mechanism (newsyslog(8)) requires ability to send
signal to a daemon in order to properly complete rotation of the logs in an "atomic"
manner without having to making a copy and truncating original file. Unfortunately
our built-in mechanism to convert "dumb" programs into daemons has no way to handle
this rotation properly. This change adds this ability, to be enabled by supplying -H
option in addition to the -o option.

I believe this was introduced in the original '-r' commit, r231911 (2012).
At the time, the scope was limited to a 1 second sleep. r332518 (2018)
added '-R', which increased the potential duration of the affected interval
(from 1 to N seconds) by permitting arbitrary restart intervals.
Instead, handle SIGTERM normally during restart-sleep, when the monitored
process is not running, and shut down promptly.
(I noticed this behavior when debugging a child process that exited quickly
under the 'daemon -r -R 30' environment. 'kill <daemonpid>' had no
immediate effect and the monitor process slept until the next restart
attempt. This was annoying.)

supervised program. The existing -r option has a hard-coded delay of one
second. This change adds a -R option which takes a delay in seconds. This
can be used to prevent log spam and rapid restarts, similar to init(8)'s
behavior of adding a delay between rapid restarts when it's supervising a
program.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
No functional change intended.
There are various new options, documented in the man page, to send the
daemon's standard output and/or standard error to a file or to syslog.
