* Furi: replace obsolete furiac_exit with osThreadExit, drop obsolete apis and test. Rename systemd to flipper and move to separate file, cleanup. ApiHal: Rename timebase to os and move freertos hooks there, move insomnia api to power module. * Furi: new thread helper * Furi: cleanup thread documentation * Flipper, AppLoader: update to use FuriThread. Update tasks signatures to match FuriThreadCallback signature. * F4: rename API_HAL_TIMEBASE_DEBUG to API_HAL_OS_DEBUG * Applications: rename FuriApplication to FlipperApplication, use FuriThreadCallback signature for apps. * C++ app template sample, new exit method
