* Improve RNG error handling * Sync RTC shadow registers on Stop mode exit * Implement working STOP2 mode * Fix formatting * FuriHal: disable SWD pins if debug is disabled * Power: cleanup battery info view, handle zero current report from gauge * Fbt: add command line argument for extra global defines * FuriHal: cleanup debug defines in power and os, drop deep_insomnia counter. * Add a setting to disable deep sleep * Clean up furi_hal_power * FuriHal,FapLoader,Debug: implement debug in stop mode, workaround resume in stop * FuriHal: document OS and power subsystems debugging * Furi: enable debug interface on crash --------- Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com>
