Chris Bieneman 8b5906ea7f [obj2yaml] [yaml2obj] Basic support for MachO::load_command 
This patch adds basic support for MachO::load_command. Load command types and sizes are encoded in the YAML and expanded back into MachO.

The YAML doesn't yet support load command structs, that is coming next. In the meantime as a temporary measure when writing MachO files the load commands are padded with zeros so that the generated binary is valid.

Chris Bieneman fc8892771e [yaml2macho] Handle mach_header_64 reserved field 
I've added the reserved field as an "optional" in YAML, but I've added asserts in the yaml2macho code to enforce that the field is present in mach_header_64, but not in mach_header.

Chris Bieneman a23b26f466 [yaml2obj] Support for dumping mach_header from yaml

Chris Bieneman b83c187195 Initial add for MachO support for yaml2obj 
Adding the initial files for adding MachO support to yaml2obj. Passing a MachO file will result in an error.

I will be implementing obj2yaml and yaml2obj for MachO in parallel so that one can be used to test the other.
