Mikolaj Golub 9da0ef1316 1. Properly clean pid files in the case of the error.
2. Write the supervisor pid before the restart loop, so we don't
   uselessly rewrite it after every child restart.
3. Remove duplicate ppfh and pfh initialization.

John-Mark Gurney 32b17786bd add support for writing the pid of the daemon program to a pid file so
that daemon can be used w/ rc.subr and ports can use the additional
functionality, such as keeping the ldap daemon up and running, and have
the proper program to signal to exit..

Mikolaj Golub 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.

Mikolaj Golub 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.

Guy Helmer 704523b073 Revert 229667: After some discussion of this change, it seems it is
better to leave the pidfile open where it was. Add a note to the
man page describing pidfile strategies to use if the daemon is to
be run as a user other than root.

Guy Helmer 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.

Poul-Henning Kamp 846be7bd0e Give daemon(8) the ability to create a pid-file. Since the target program
does not know anything about the pid-file and we don't keep a babysitting
process for the task, the pid-file will linger.
