base-files: allow reusing of boolean value extraction logic
The `functions.sh` script has `config_get_bool()` function, which is usable when using UCI config direct access API, but there is no equivalent for the callback API. Introduce `get_bool()` function to allow reusing it from init scripts. Example: ```sh option_cb() { local option="$1" local value="$(get_bool "$2")" ... } ``` Signed-off-by: Oldřich Jedlička <oldium.pro@gmail.com>
