First stab at OTA-update Introduce new testing-app example. Add a new coap error code for blockwise transfer. Add include-file for bootloader callbacks (jumptable). Note that only the bootloader for osd-merkur-256 will support OTA-update, the -128 simply has not enough flash memory, so only in the -256 we have the bootloader functions in the jump-table of the bootloader and in the bootloader-if.h include-file.

New method for determining active partition

Fix OTA update Image 0 did not work. We now get rid of bootloader_backup_irq_table and do this manually: We may not write to address 0 while an image is running. So for image 0 we write the lower 8 pages to the backup address. For all other images (ony image 1 currently) we write to *both*, the original address *and* the backup address. This is done because some addresses in the lower 8 pages *are* used at the original address and the bootloader doesn't (want to) know which addresses are which. There are more safeguards now: We refuse to write to the active or boot_next image (if boot_next is not boot_default). We mark the uploaded partition as not ok. Needs latest bootloader with commit ID a5771ae033b57.
