- Integrated with r_debug module
- Hardware breakpoints will be handled by the debug backend
- Breakpoints support software/hardware, lil/big endian, trace, enable/disable
- Plugin infrastructure adding software breakpoint templates
- Added x86 and arm software breakpoint plugins
* Some work on the 'db' command to manage debugger breakpoint
* Added empty dH to transplant process between debugger backends
