Adds a configurable version string to a known location at the end of mboot flash section. Also stores the options mboot was built with, eg usb and which filesystems are supported. A board can override the defaults, or disable the version string entirely by setting MBOOT_VERSION_ALLOCATED_BYTES=0. Signed-off-by: Victor Rajewski <victor@allumeenergy.com.au>
