- r2 -d gdb://<host>:<port>
- register maps not yet implemented
- some basic step/continue should work in cfg.debug=true
- gdbwrap instance is shared between RIO and RDebug
* RDebug is now arch-sensitive
- Plugins describe which architectures and register sizes are supported
- Native debugger is restricted to local CPU
- Remote debugger (GDB) arch can be specified with -e asm.arch=arm
* Fix some random warnings
* Move R_ASM_ARCH into R_SYS_ARCH
- Helper functions to translate id to string and string to id
are now in util/sys.c (r_util)
- Move all R_SYS_* from r_util to r_types
- Endianness, OS, CPU and regsize is now 'global'
