* Furi: remove direct FreeRTOS timers use * Furi: eliminate FreeRTOS headers leak. What did it cost? Everything... * SubGhz: proper public api for protocols. Format Sources. * Furi: slightly less redundant declarations * Desktop: proper types in printf * Sync API Symbols * Furi: add timer reset and fix dolphin service, fix unit tests * Furi: proper timer restart method naming and correct behavior in timer stopped state. --------- Co-authored-by: hedger <hedger@nanode.su>
