libdebugger: ARM fixes for Cortex-A8 and ARM mode.
- Fix destorying the target and thread parts.
- Fix the ARM backend to support Cortex-A8 and ARM mode code.
- Use the DBGDSCR interrupt mask when single stepping.
- Use the DBGDSCR method of entry to debug mode to filter the
execptions.
- Add support for BSPs to control the ARM backend.
