base-files: move urandom seed bits into separate package So it's possible to install or remove it as needed. Tested-by: Lucian Cristian <lucian.cristian@gmail.com> Signed-off-by: Petr Štetiar <ynezz@true.cz>

treewide: drop shebang from non-executable lib files This drops the shebang from another bunch of files in various /lib folders, as these are sourced and the shebang is useless. Fix execute bit in one case, too. This should cover almost all trivial cases now, i.e. where /lib is actually used for library files. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>

urandom-seed: 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 OpenWRT and tweaked as needed: <https://git.zx2c4.com/seedrng/about/>. This commit imports it into the urandom-seed package and wires up the init scripts to call it. This also is a significant improvement over the current init script, which does not robustly handle cleaning up of seeds and syncing to prevent reuse. Additionally, the existing script creates a new seed immediately after writing an old one, which means that the amount of entropy might actually regress, due to failing to credit the old seed.
