37820b8746 Add an option to daemon(8) to specify a delay between restarts of a
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.

1de7b4b805 various: general adoption of SPDX licensing ID tags.
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.

WITH_META_MODE we get auto objdir creation, the ability to

2. Write the supervisor pid before the restart loop, so we don't
   uselessly rewrite it after every child restart.

195fc497a2 If the supervising process receives SIGTERM, forward it to the spawned
process.  Normally it will cause the child to exit followed by the
termination of the supervisor after removing the pidfile.

This looks like desirable behavior, because termination of a
supervisor usually supposes termination of its charge. Also it will
fix the issue with stale pid files after reboot due to init kills a
supervisor before its child exits.

2ad4302785 The pidfile_open(3) is going to be fixed to set close-on-exec in order
not to leak the descriptor after exec(3). This raises the issue for
daemon(3) of the pidfile lock to be lost when the child process
executes.

To solve this and also to have the pidfile cleaned up when the program
exits, if a pidfile is specified, spawn a child to exec the command
and wait in the parent keeping the pidfile locked until the child
process exits and remove the file.

074db536b3 Allow daemon(8) to run pidfile_open() before relenquishing privileges
so pid files can be written in /var/run when started as root.

I do not expect this to cause any security issues, but if anyone objects
it could be easily reverted.
