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.

eaa42da9a6 Use cgroup.kill in cgroup_cleanup when possible
The old code is moved to a cgroup_fallback_cleanup function and only
 called if cgroup2_kill fails.

 This fixes #454.

4fb4674374 fix unified cgroups v2 setup
The cgroups v2 setup required the rc_cgroups_controllers variable
to be set to the list of controllers to enable regardless of whether the
mode was hybrid or unified.

This makes sense for hybrid mode since the controllers can't be in both
the cgroups v1 and v2 hierarchies, but for unified mode we should enable
all controllers that are configured in the kernel.

b085b2cda5 etc: create default rc.conf
Before now, /etc/rc.conf was created by the build system from multiple
rc.conf.* file fragments and there was no reason for this.

5af58b4514 Rewrite the core parts in C. We now provide librc so other programs can
query runlevels, services and state without using bash. We also provide
libeinfo so other programs can easily use our informational functions.

As such, we have dropped the requirement of using bash as the init script
shell. We now use /bin/sh and have strived to make the scripts as portable
as possible. Shells that work are bash and dash. busybox works provided
you disable s-s-d. If you have WIPE_TMP set to yes in conf.d/bootmisc you
should disable find too.
zsh and ksh do not work at this time.

Networking support is currently being re-vamped also as it was heavily bash
array based. As such, a new config format is available like so
config_eth0="1.2.3.4/24 5.6.7.8/16"
or like so
config_eth0="'1.2.3.4 netmask 255.255.255.0' '5.6.7.8 netmask 255.255.0.0'"

We will still support the old bash array format provided that /bin/sh IS
a link it bash.

ChangeLog for baselayout-1 can be found in our SVN repo.
