pancake 822a33377b * Initial working implementation of the r_diff with delta in C
- Uses the mercurial's C algorithm for delta diffing
  - Remove r_diff_lines .. do we need a line-level diffing tool?
  - Remove -l flag from radiff2
* Rename RIo to RIO
* Added r_reg_arena_new () to simplify arena creation
  - Some sanity fixes in r_reg arena.c
* Add -C in rasm2 to output in C string format
* Initial working implementation of r_debug_execute to inject code
  in child process and restore memory and registers
  - Returns %a0 register value in ut64
* Added 'c' command to r_core - to compare -- just dummy
  - Will use r_diff
  - if rdiff callback returns NULL, we must stop scanning
  - old r_diff_buffers_delta is now named buffers_radiff
  - Added test files in diff/t/{file1,file2}
* Added doc/plugins documentation file
* Fix ${EXT_SO} in bin/p and asm/p (dejavu?)
* Added dummy asm_gas r_asm plugin
* Various random syntax fixes
* Rename 'dbg.ptrace' to 'dbg.native'
* Added r_debug_io_bind () to sync dbg and bp io_bind
* r_debug_map_list is now in a nicer format
* Append ${EXT_EXE} in diff/t
* Add missing util/log.c and vapi/r_line.vapi

Debugger API for radare2
========================

We need to connect multiple pieces...

debugger engine: vm, qemu, bochs, ptrace, mach, w32dbg...

controlflow commands: (should be splitted in two layers)

 - continue -- low level
 - step     -- low level
 - trace   --- high level one
 - ...

 the control flow commands depend on other stuff to decide
 how to work..this is for example if the arch doesnt supports
 continuation, we should provide a step based continue. The
 same when a watchpoint is activated and the arch didnt
 supports hardware regs for this purpose.

We also need a load/store/dump/restore functions to move the
program from one engine to another (ptrace -> qemu).. we should
provide a way for all this operations between them.

[continue]
    |--- check if bp api allow us to continue or we should step into..
    |--- check if debug plugin supports continue

[getregs]
    |--- r_reg give us a list of registers
    |    - dr (show bitsize debug registers) // 32 by default
    |    - dr 32 (show 32 bit debug registers) // depends on size
    |    - dr:eax (show 'eax' register value)
    |    - dr:al  (show 8bit register 'al')
    |    - dr eax=33 (set 'eax' register value)
