7b2e8f9efd librc: mark rc_deptree_* functions as mallocs
(This is analogous to the rc_stringlist change.)

This gives a hint to the compiler that allocations (return values)
from this function should be paired with a corresponding dealloc/free
function.

17de4e5dfd librc: mark stringlist functions as mallocs
This gives a hint to the compiler that allocations (return values)
from this function should be paired with a corresponding dealloc/free
function

In this case, it means that every rc_stringlist that rc_stringlist_new()
returns should eventually be freed by calling rc_stringlist_free(ptr)
where ptr is the relevant rc_stringlist.

We have to add a test for this into the build system
because only GCC supports this for now. In future, we might
be able to use meson's has_function_attribute (it does support
'malloc', just not AFAICT 'malloc with arguments').

f81bb7e2c4 seedrng: use posix positional params to avoid space splitting
The value of ${seed_dir} may have spaces in it, making the current

076c2552ae Use seedrng for seeding the random number generator
The RNG can't actually be seeded from a shell script, due to the
reliance on ioctls. For this reason, the seedrng project provides a
basic script meant to be copy and pasted into projects like OpenRC and
tweaked as needed: https://git.zx2c4.com/seedrng/about/

This commit imports it into OpenRC and wires up /etc/init.d/urandom to
call it. It shouldn't be called by other things on the system, so it
lives in rc_sbindir.

Closes #506.
Closes #507.

98feac173e init.d/bootmisc.in: prevent error due to nonexistant file
During boot if the "previous_dmesg" setting is enabled in
/etc/conf.d/bootmisc then during the 1st boot of a machine the
bootmisc init.d script will attempt to move a nonexistant dmesg
file, so generating an error on the console.

Modify the script to only move an existing file.

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.
