Major rework of mkamsboot, extending work done by Rafael Carre. We now build one "dualboot.bin" mini-bootloader per target and embed it in the mkamsboot binary. The user of mkamsboot just needs to provide an original firmware file, and a Rockbox bootloader file. This code currently supports just the Clip (hardware revision 1) and the E200v2 - button checks are needed for the other V2 targets. NOTE: This is completely untested on-target, and may brick your device.
