af70862a7a supervise-daemon: use a default pid file if one is not specified
Since the pid file is internal to us, start moving toward deprecating it
by not requiring the user to specify it.
In the next release, I plan on working on code to start phasing out the
use of a pid file if this is possible.

77262c359c supervise-daemon: add support for a fifo
This will allow us to signal the daemon we are supervising as well as
send other commands to the supervisor in the future.

This fixes #227.

7f23e0461d supervise-daemon: rework signal handling and main loop
This is needed in preparation for adding support for a fifo to allow us
to communicate with the supervisor to ask it to signal the child it is
supervising.

ff4af908a5 Revert "checkpath: use O_PATH when available"
This reverts commit 2af0cedd59.

After speaking with Luis Ressel on the Gentoo selinux team, I am reverting
this commit for the following reasons:

- Luis told me that he feels this is not the solution we need to address
  the concern with checkpath; I will be working with him on another
  solution.

- There are concerns about the way the path variable was handled
  and the assert() call.
  The path variable should be dynamically allocated using xasprintf
  instead of defining a length at compile time. This would eliminate the
  need for the assert() call.

- It introduces the definition of _GNU_SOURCE which makes it
  easier to introduce portability concerns in the future (see #262).

2af0cedd59 checkpath: use O_PATH when available
This avoids opening directories/files with read permission, which is
sometimes rejected by selinux policy.

0f704402a2 supervise-daemon: make the pidfile an implementation detail
The pidfile of the supervisor doesn't need to be adjustable by the
service script. It is only used so the supervisor can stop itself when
the --stop option is used.

2504a2c25b Do not complain if interrupted by a signal
In start-stop-daemon and rc-schedules, we were printing out a warning if
the nanosleep call was interrupted by a signal, but we did not treat
this as an error situation other than displaying the message, so there
is no need for the message.

c1e582586d supervise-daemon: add health checks
Health checks are a way to monitor a service and make sure it stays
healthy.

If a service is not healthy, it will be automatically restarted after
running the unhealthy() function to clean up.

3f918161aa openrc-shutdown: Add scheduled shutdown and the ability to cancel a shutdown
You can now schedule a shutdown for a certain time or a cpecific number
of minutes into the future.

When a shutdown is running, you can now cancel it with ^c from the
keyboard or by running "openrc-shutdown -c" from another shell.

710c874e6e supervise-daemon: fix respawn_max off by one
Fix the comparison between respawn_count and respawn_max so that
respawn_max = 1 will allow for one respawn. Since respawn_count is
incremented before the comparison, use a 'greater than' comparison
so that respawn will be triggered when respawn_count is equal to
respawn_max.
