update_engine: New BootControlInterface class.
The new BootControlInterface class is a platform-independent
abstraction to control the bootloader. It provides methods for setting
what partition slots are available for booting and getting the
bootloader status about the available slots.
The Chrome OS specific implementation of the bootloader was moved to
the BootControlChromeOS which now depends on the vboot_host
implementation used in Chrome OS. Follow up CL will implement the
equivalent class for Brillo.
