- shut down the display and reboot the camera. 
- bootfile is the name of the file to boot.
-  Must be an unencoded ARM binary, will be loaded at 0x1900
-  For cameras which use encoded diskboot, loader/<camera>/main.bin may be used
-  For cameras which do not use encoded diskboot, DISKBOOT.BIN may be used
-  No sanity checking is performed on the binary, except that the size is >= 4 bytes
- If bootfile is NULL, camera firmware is rebooted. DISKBOOT.BIN will be loaded or not according to normal rules
- returns 0 on failure, does not return on success
- does NOT save camera settings to flash
- does NOT retract lens before rebooting
- calling from playback mode is recommended
+ reboot, optionally loading a different binary
+ see lib/armutil/reboot.c for documentation
