Fix the stub in many way to correctly detect the STMP family and act upon that. Drop some unused commands and bump version. Rewrite the tool to allows scripting in lua and load the register description from an XML file using the regtools. Introduce a new tool to load and run code using the hwstub (either binary format or Rockbox additive scramble format). Also switch to an optimise version of the memcpy/move/set functions to correctly handle alignement issue (like writing a full word/half-word when possible for registers which is crucial) Change-Id: Id1d5cfe0b1b47e8b43900d32c5cd6eafae6414f6
