* Deprecate rarc2 and rarc2-tool

- Replaced by ragg2 - the new r_egg based tool for r2
* Add r_egg_assemble as a 2nd step for compilation
* Fix memory leak in r_egg_free
* Add support for 'cmp' and more 'test' variants for x86.nz
  - Ignore 'dword ptr' string
  - More test cases
* Fix SCSIZE issue in rasc2 -s
