minor recovery changes
- add the --just_exit option to make recovery exit normally without doing anything
- make it possible to build updater extensions in C++
- add the clear_display command so that the updater binary can request
recovery switch to the NONE background UI
These are all used to support the notion of using OTA as a factory
reflash mechanism.
