proxmark3/armsrc/start.c
iceman1001 53d5dc643f CHG: fiddled with the headerfiles... and makefile... Tried to make them behave nice. So it isnt a hell to add new functions from third-party (like des, aes etc)
Added a lot of #ifndef ,   extern C,
Move inside from ARMSRC -> THUMBS,  which made the compiled image smaller.. I don't know if it broke anything.
Moved MF_DBGLEVEL definitions into common.h
Moved print_result from util.c into appmain.c
Also split up some struct typedef  into header files so they could be reused in other code places.

''' danger '''  this might have broken stuff...
