Support MSP430 architecture

[lucab]

Avatar is currently ARM-only (with several sub-arch supported). It would be good to expand the framework to support other popular embedded architecture, starting from MSP430.

The recent Matasano/Stripe CTF showed that interest is rising into it.

mspdebug could be repurposed and plugged as both avatar emulator and target-bridge. Remote forwarding has to be developed.

FIE is perfoming symbolic execution through KLEE, so it could probably be plugged easily into mspdebug.

This would be nice but it would be a lot easier to start with an architecture supported by QEMU (or S2E).
I see Intel as the best candidate (yes it's present in many embedded systems!), then maybe PPC or Mips ?
MSP430 would be nice as well, actually using mspdebug is a good idea.

FIE is interesting but requires source code, which isn't impossible, but is against one of the design choice of Avatar...
