[FL-2263] Flasher service & RAM exec (#1006)
* WIP on stripping fw
* Compact FW build - use RAM_EXEC=1 COMPACT=1 DEBUG=0
* Fixed uninitialized storage struct; small fixes to compact fw
* Flasher srv w/mocked flash ops
* Fixed typos & accomodated FFF changes
* Alternative fw startup branch
* Working load & jmp to RAM fw
* +manifest processing for stage loader; + crc verification for stage payload
* Fixed questionable code & potential leaks
* Lowered screen update rate; added radio stack update stubs; working dfu write
* Console EP with manifest & stage validation
* Added microtar lib; minor ui fixes for updater
* Removed microtar
* Removed mtar #2
* Added a better version of microtar
* TAR archive api; LFS backup & restore core
* Recursive backup/restore
* LFS worker thread
* Added system apps to loader - not visible in UI; full update process with restarts
* Typo fix
* Dropped BL & f6; tooling for updater WIP
* Minor py fixes
* Minor fixes to make it build after merge
* Ported flash workaround from BL + fixed visuals
* Minor cleanup
* Chmod + loader app search fix
* Python linter fix
* Removed usb stuff & float read support for staged loader == -10% of binary size
* Added backup/restore & update pb requests
* Added stub impl to RPC for backup/restore/update commands
* Reworked TAR to use borrowed Storage api; slightly reduced build size by removing `static string`; hidden update-related RPC behind defines
* Moved backup&restore to storage
* Fixed new message types
* Backup/restore/update RPC impl
* Moved furi_hal_crc to LL; minor fixes
* CRC HAL rework to LL
* Purging STM HAL
* Brought back minimal DFU boot mode (no gui); additional crc state checks
* Added splash screen, BROKEN usb function
* Clock init rework WIP
* Stripped graphics from DFU mode
* Temp fix for unused static fun
* WIP update picker - broken!
* Fixed UI
* Bumping version
* Fixed RTC setup
* Backup to update folder instead of ext root
* Removed unused scenes & more usb remnants from staged loader
* CI updates
* Fixed update bundle name
* Temporary restored USB handler
* Attempt to prevent .text corruption
* Comments on how I spent this Saturday
* Added update file icon
* Documentation updates
* Moved common code to lib folder
* Storage: more unit tests
* Storage: blocking dir open, differentiate file and dir when freed.
* Major refactoring; added input processing to updater to allow retrying on failures (not very useful prob). Added API for extraction of thread return value
* Removed re-init check for manifest
* Changed low-level path manipulation to toolbox/path.h; makefile cleanup; tiny fix in lint.py
* Increased update worker stack size
* Text fixes in backup CLI
* Displaying number of update stages to run; removed timeout in handling errors
* Bumping version
* Added thread cleanup for spawner thread
* Updated build targets to exclude firmware bundle from 'ALL'
* Fixed makefile for update_package; skipping VCP init for update mode (ugly)
* Switched github build from ALL to update_package
* Added +x for dist_update.sh
* Cli: add total heap size to "free" command
* Moved (RAM) suffix to build version instead of git commit no.
* DFU comment
* Some fixes suggested by clang-tidy
* Fixed recursive PREFIX macro
* Makefile: gather all new rules in updater namespace. FuriHal: rename bootloader to boot, isr safe delays
* Github: correct build target name in firmware build
* FuriHal: move target switch to boot
* Makefile: fix firmware flash
* Furi, FuriHal: move kernel start to furi, early init
* Drop bootloader related stuff
* Drop cube. Drop bootloader linker script.
* Renamed update_hl, moved constants to #defines
* Moved update-related boot mode to separate bitfield
* Reworked updater cli to single entry point; fixed crash on tar cleanup
* Added Python replacement for dist shell scripts
* Linter fixes for dist.py +x
* Fixes for environment suffix
* Dropped bash scripts
* Added dirty build flag to version structure & interfaces
* Version string escapes
* Fixed flag logic in dist.py; added support for App instances being imported and not terminating the whole program
* Fixed fw address in ReadMe.md
* Rpc: fix crash on double screen start
* Return back original boot behavior and fix jump to system bootloader
* Cleanup code, add error sequence for RTC
* Update firmware readme
* FuriHal: drop boot, restructure RTC registers usage and add header register check
* Furi goes first
* Toolchain: add ccache support
* Renamed update bundle dir
