* Add littlefs submodule * Furi: add mutex in logging, fix issues with corrupted printf * ApiHal: disable debug traces in ble glue * App-loader: more logs * Passport: fix invalid DolphinState usage * ApiHal, linker script: flash API is now aware of free space, complete abstraction layer for storage * Internal Storage: littlefs based storage services with key value API. Migrate dolphin state to new storage API.
