fd1e4a384a add option for OOM score adjustment
This commit adds a new --oom-score-adj option to start-stop-daemon and
supervise-daemon, as well as an equivalent SSD_OOM_SCORE_ADJ environment
variable. If either of these are specified (with the command-line
option taking precedence), then the specified adjustment value is
written to /proc/self/oom_score_adj after forking but prior to exec'ing
the daemon (at the time when nice and ionice are applied).

Additionally, per a suggestion by Mike Frysinger, the suggested values
for the SSD_NICELEVEL, SSD_IONICELEVEL, and SSD_OOM_SCORE_ADJ variables
in the example config file are now given as zeros, which are the
kernel's default values of these process knobs for the init process at
boot. Note that uncommenting any of these zero-valued suggestions will
cause SSD/SD to set the corresponding process knob affirmatively to
zero, whereas leaving the variable unset (and the equivalent command-
line option unspecified) means SSD/SD will not change the corresponding
process knob from its inherited value.

See: https://github.com/OpenRC/openrc/pull/435#discussion_r688310672
This fixes #435.

This makes the URIs shorter and dynamic: whatever the default branch
the repo uses will be used.

5f6d7ac028 supervise-daemon: implement SSD_IONICELEVEL
supervise-daemon was apparently overlooked when support for the
SSD_IONICELEVEL environment variable was added. This commit brings
supervise-daemon up to parity with start-stop-daemon with respect to
this environment variable.

b6fef599bf checkpath: fix CVE-2018-21269
This walks the directory path to the file we are going to manipulate to make
sure that when we create the file and change the ownership and permissions
we are working on the same file.
Also, all non-terminal symbolic links must be owned by root. This will
keep a non-root user from making a symbolic link as described in the
bug. If root creates the symbolic link, it is assumed to be trusted.

On non-linux platforms, we no longer follow non-terminal symbolic links
by default. If you need to do that, add the -s option on the checkpath
command line, but keep in mind that this is not secure.

This fixes #201.

2d31b0a3f8 man: supervise-daemon: fix various style issues
The .Dt header is supposed to be all caps.  This was mixing case.

The options block was being incorrectly indented due to a missing .El.

Some of the new options were missing the .It block, so add that.

Finally, the -D option was missing capitalization.

c1ffe4d9f2 man/openrc-run.8: fix mountinfo args.
The "Ar" tag for the mountinfo command contained a typo (leading
space) that resulted in the tag being output verbatim; that is,

  mountinfo ... .Ar mount1 mount2

rather than e.g.

  mountinfo ... <mount1> <mount2>

This commit deletes the leading space to fix the output.

This fixes #204.

The BUILTINS are all surrounded by Xo...Xc tags, but the opening "Xo"
was missing from the two commands fstabinfo and mountinfo. This commit
adds them, and thereby fixes the spacing when viewed by man.

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.
