- fixed endianness helper macros (thanks to obilix and wiml for finding and fixing this bug)

- added declarations for 32bit fileio access functions (network byte order)
- fixed bug in etm trace dump file handling
- added XScale trace buffer decoding
- fixed arm_simulator ERROR numbers (-7xx used twice)
- fixed minor bug in debug output in stellaris.c
