- Fixed bug in pathmove for XScale

Browse Source 
- added virtual address to working_area.
- Improved error messages in a number of places
- Added ERROR_COMMAND_SYNTAX_ERROR that commands can return to have syntax printed
- Added help for some config commands
- Added verification of sw breakpoints with ERROR() message
- Removed a couple of exit()'s and replaced with error message
- cosmetic fix to armv4_5.c, easier to read
- added polymorphic(with default) virt2phys and mmu enable query function to target.h
- added virt2phys command that uses target->type->virt2phys() fn
Thanks to Øyvind Harboe
