FS#10253 : mkamsboot v1.0

- Bump version to 1.0
- Add Clipv2 target
- Make mkamsboot work as a library (work by domonoky : FS#10185, with a few modifications by me)
  . Use a macro with variadic arguments for error cases in functions which might error.
  . Add detailed descriptions to functions exported by the library (in the header file)
- modify bin2c.c to produce only one pair of .c/.h files with several files embedded in it
- move files needing to be built by an ARM cross compiler into dualboot/
- commit produced .c/.h files (containing nrv2e_d8.S and dualboot.S built for Clip, Fuze, e200v2, c200v2, m200v4, Clipv2)
- Write a real README file
- cosmetics: indent dualboot.S properly, remove trailing spaces, limit lines to 80 characters
- comments: add/correct comments in dualboot.S and mkamsboot.c
- move back extract_fw.c to utils/AMS/hacking
