Brainfuck support for r2

Plugins for brainfuck:

asm.bf - brainfuck assembler and disassembler
debug.bf - debugger using bfvm
anal.bf - code analysis for brainfuck
bp.bf - breakpoints support (experimental)

To debug a brainfuck program:

r2 -D bf bfdbg:///tmp/bf

> dc    # continue
> x@scr # show screen buffer contents

The debugger creates virtual sections for code, data, screen and input.

TODO

add support for comments, ignore invalid instructions as nops
enhance io and debugger plugins to generate sections and set arch opts
