osmocon: * introduce support for "non-secure" romloader inside Calypso/Calypso lite, "-m romload", tested on the BenQ Siemens A38
* automatically add the required 1003 magic for the C139, C140 and J100i "-m c140/c140xor", intended for loading loader.ramload.bin, and loading the application itself with "osmoload memload" on these targets * replace null-terminated string "ftmtool" with uint8_t (length was 8, so the ftmtool message was only recognized when the byte following to our allocated buffer memory was 0x00) * fix minor compiler warnings * add copyright message Signed-off-by: Steve Markgraf <steve@steve-m.de>
