Ocloc asm/disasm support for zebin

This commit adds option to disassemble and assemble zebinary.

Disasm disassembles zebinary into sections. Text sections are
translated to assembly, relocations and symbols are
translated into human readable format.

Asm assembles zebinary from files generated by disasm.
