h1x0/h300: bring the two bootloaders more in sync
The most major change here is the porting of the failsafe boot
menu and eeprom settings support from the h1x0 bootloader to the
h300 bootloader. This has been successfully tested already and
indeed works about the same as it does on the h1x0 bootloader.
The other major change is the addition of new code to both
bootloaders that will retry the flash boot function after
exitting disk mode. It still falls back to booting from disk
if this either fails or is not configured to boot from flash.
There were also various other modifications to bring the two
closer in sync so there are fewer differences.
