ARM Cortex-M3 fault exceptions debugging support

More convinient replacement for http://www.freertos.org/Debugging-Hard-Faults-On-Cortex-M-Microcontrollers.html

Execution automatically stops when catching fault and you may examine fault context via function arguments.

Also with .gdbinit script provided you may try to rollback (unwind/return) to place where fault occured. It's not always possible.

Tested with gcc compiler and CMSIS.
