6e214b2616 capabilities: Add support for Linux capabilities(7)
This adds capabilities for start-stop-daemon by adding --capabilities
option. As a result, the user can specify the inheritable, ambient and
bounding set by define capabilities in the service script.

This fixes #314.

301161a7a4 use HEAD in git URIs to point to the default branch
This makes the URIs shorter and dynamic: whatever the default branch
the repo uses will be used.

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.

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.

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.

ddbdb69658 add more variables for start-stop-daemon and supervise-daemon options
Add the following variables to expose more arguments that can be passed
to start-stop-daemon or supervise-daemon:

- directory will be passed to --chdir
- error_log will be passed to --stderr
- output_log will be passed to --stdout
- umask will be passed to umask

This is for #184.

82da844b42 implement "unsupervised" status
The unsupervised status is to be used when a supervisor of a supervised
service dies but leaves the service daemon itself running.

a428c325a9 add "unsupervised" status and return code 64 to supervise-daemon status function
This is to be used if the service is being supervised and the
supervisor is somehow killed.

Currently, this is very linux specific, but I will expand to other
platforms, patches are welcome.

17b5cc78d3 add retry option to supervise-daemon
The --retry option for supervise-daemon defines how the supervisor will
attempt to stop the child process it is monitoring. It is defined when
the supervisor is started since stopping the supervisor just sends a
signal to the active supervisor.

This fixes #160.

4c89e3f5fa supervise-daemon:create multiple options from --respawn-limit
This creates --respawn-delay, --respawn-max and --respawn-period. It was
suggested that it would be easier to follow if the options were
separated.

This is for #126.

3673040722 supervise-daemon: add a --respawn-limit option
Allow limiting the number of times supervise-daemon will attempt to respawn a
daemon once it has died to prevent infinite respawning. Also, set a
reasonable default limit (10 times in a 5 second period).

This is for issue #126.

d6c30ab12a Revert "Remove eval calls from supervisor start functions"
This reverts commit 0d1f1010c2.
We need the eval in case someone uses something like:
command_args="this \"is a\" test"

This is related to #77.

The supervise-daemon process is meant to be a lightweight supervisor
which can monitor and restart a daemon if it crashes.
