DFU flashing of apps sometimes aborts, and although rare this leads to broken devices if no boot button or serial/jtag access exists, because the bootloader will keep trying to start a half-flashed app that then crashes at some point. The easiest fix that works with existing bootloaders is to prepend a small 512 byte stub that calculcates the crc and compares it with the crc calculated at build time, and then either starts the actual app, or sets the dfu flag and resets. This ensures we either have a working, running app, or end up in the bootloader, ready to flash again. For obvious reasons this only applies to dfu apps, and not to flash targets like the actual bootloader itself. Change-Id: Id6df0486c8b779889d21800dc2441b3aa9af8a5f
