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

separate lock file. Also various stylistic cleanups.

* rewrite tests to work with meson

This ports our tests to meson and makes them able to be run in parallel.

* add tests to ci

* rewrite test/check-trailing-newlines in bash

This test was using a GNU sed command which does not work on Alpine Linux.

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.
