To enable more complex sequencing of the bootmenu, autoboot, and bootretry, handle changes to the bootretry variable between tries. This makes it possible to turn bootretry off (e.g. to drop to a shell) and then back on again.
This makes it possible to have a persistent bootmenu (the only way to navigate U-Boot on devices like smartphones which lack a physical keyboard) by having bootcmd be defined to launch the bootmenu. This allows for menu options like enabling USB mass storage gadget to return back to the boot menu once the gadget is shut down.
