* SYSTEM: tickless mode with deep sleep. * Move FreeRTOS ticks to lptim2 * API: move all sumbodules init routines to one place. Timebase: working lptim2 at tick source. * API Timebase: lp-timer routines, timer access safe zones prediction and synchronization. FreeRTOS: adjust configuration for tickless mode. * NFC: support for tickless mode. * API Timebase: improve tick error handling in IRQ. Apploader: use insomnia mode to run applications. * BLE: prevent sleep while core2 starting * HAL: nap while in insomnia mode * init records work * try to implement record delete * tests and flapp * flapp subsystem * new core functions to get app stat, simplify core code * fix thread termination * add strdup to core * fix tests * Refactoring: remove all unusued parts, update API usage, aggreagate API sources and headers, new record storage * Refactoring: update furi record api usage, cleanup code * Fix broken merge for freertos apps * Core, Target: fix compilation warnings * Drop firmware target local * HAL Timebase, Power, Clock: semaphore guarded access to clock and power modes, better sleep mode. * SD-Filesystem: wait for all deps to arrive before adding widget. Core, BLE: disable debug dump to serial. * delete old app example-ipc * delete old app fatfs list * fix strobe app, add input header * delete old display driver * comment old app qr-code * fix sd-card test, add forced widget update * remove unused new core test * increase heap to 128k * comment and assert old core tests * fix syntax Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
