* Split core/cmd.c into disasm.c and core/visual.c into vmenus.c * Fix some warnings reported by valgrind * Chop instructions disassembled by udis86 * Fix visual prompt display in debugger mode * Added 'pdi' and 'pdf' commands - Used to print just instructions or lengths - Documented via 'pd?' * Added initial work on a test suite for r2 - Spot a crash!
