this adds the DFU as application, allowing to flash the bootloader. a USB DFU alternative is added to flash the bootloader partition. when the DFU is started as bootloader, the partition/alternative to flash the bootloader is marked as "not available", and ineffective. the same happens for the application partition when DFU is started as application. this distinction is make at compile time, not at runtime, because of size restrictions (the bootloader was already close to the 16 kB limit). *_dfu_flash.bin should not be mixed with *_dfu_dfu.bin. *_dfu_dfu.bin should be flashed as application using the already existing DFU bootloader. once this images is started (as application), the *_dfu_flash.bin should be flashed as bootloader using the DFU application. once the DFU bootloader has been flashed, soft resetting (not re-powering) will cause the bootloader to start, allowing to flash the application with a normal image (e.g. not DFU), replacing the DFU application. this switch to DFU only happens after downloading (e.g. flashing). it is planned to have the DFU application erase itself after flashing, but this is currently not implemented.
