* Use static mutex * Add static_assert checks * Use static semaphore * Fix formatting * Use static stream buffer * Use static timer * Use static event group * Increase allocation size for stream buffer * Remove recursive bit from the mutex before freeing * Prevent service tasks from ever returning * Use static threads * Do not realloc memory when changing stack size * Use FuriSemaphore instead of raw FreeRTOS one in rpc_test * Remove redundant includes * Abolish FreeRTOS dynamic allocation * Improve FuriMutex * Improve FuriMessageQueue * Remove redundant comments and parentheses * Clean up code more * Create service threads via a dedicated constructor * Minor code improvements * Update docs for FuriThread, FuriTimer * Fix doxygen typo * Use a bigger buffer for static StreamBuffer * Furi: remove timer control block only when timer thread have completed all operations --------- Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
