Also swaps the necessary variable check in busybox/init to acoomodate OPENELEC_ARCH
may or may not exist, while LIBREELEC_ARCH will be assumed to exist.

For multi-cluster CPUs (e.g. Amlogic S912) there is a separate
policy for each CPU cluster. Add a case in init script to cover
setting up_threshold for all clusters.
This changes the order of the script to be:
Necssary bring up tasks
Setting variables to control rest of system intialization
Sourcing shared functions
Setting script functions
Doing the work of bringing the system up

The init script currently touches a file at /dev/.storage_netboot if
/storage is a remote filesystem, so that scripts that run after the root
filesystem has been switched can behave differently depending on whether
/storage is mounted locally or remotely. Add similar functionality for
/flash by touching /dev/.flash_netboot if it is a remote filesystem.
Core Kernel modules are now installed to
/usr/lib/kernel-overlays/base/lib/modules instead of /usr/lib/modules
Firmware files are installed to
/usr/lib/kernel-overlays/base/lib/firmware instead of /usr/lib/firmware
Packages can choose to install their modules and/or firmwareinto a
different overlay directory than base so they are not automatically enabled.
A new systemd service kernel-overlays, which is run before any modules
are loaded, adds overlays enabled via /storage/.cache/kernel-overlays/*.conf
These conf files must either contain the name of a system overlay,
which will then be searched for in /usr/lib/kernel-overlays/, or an
absolute path starting with '/'.
Overlaying is implemented by symlinking files from the overlays
to /usr/lib/modules and /usr/lib/firmware as not all platforms
support overlayfs.
This overlaying system can also be used by addons to provide optional
kernel modules and/or firmware by storing the absolute path to the addon
directory in the conf file and shipping kernel modules in
<addondir>/lib/modules/<KERNELVER>.
To save space only symlinks for modules matching the currently
running kernel version are created as addons may want to ship
modules for older kernel versions as well to be backward-compatible
to older LibreELEC versions.
Changes since v1:
- fixup kernel-overlays-service: add before kmod-static-nodes.service
Fix static device nodes for module autoloading not being created.
- fixup kernel-overlays-service: fail if /usr/lib/modules exists
- squash kernel overlays: use get_kernel_overlay_dir in linux/package.mk
- Add support for firmware files via kernel overlays
- config/functions: include kernel overlays in addon installation
