The MachO export trie is a serially encoded trie keyed by symbol name. This code parses the trie and preserves the structure so that it can be dumped again.

This adds support for YAML round tripping dyld info lazy bindings. The storage and format of these is the same as regular bind opcodes, they are just interpreted differently by dyld, and can have DONE opcodes in the middle of the opcode lists.

This adds support for YAML round tripping dyld info weak bindings. The storage and format of these is the same as regular bind opcodes, they are just interpreted differently by dyld.

This adds support for YAML round tripping dyld info bind opcodes. Bind opcodes can have signed or unsigned LEB128 data, and they can have symbols associated with them.

The uuid_command was duplicating the load_command.cmdsize field. This removes the duplicate from the YAML mapping and from the test cases.

This adds support for handling unknown load commands, and a bogus_load_command tests.
Unknown or unsupported load commands can be specified in YAML by their hex value.

Now that MachO load command fields are fully covered we can fill unaccounted for bytes with 0. That allows us to sparsely specify YAML to simplify tests.
Simplifying load_commands test accordingly.

This adds support for all the MachO *_command structures. The load_command payloads still are not represented, but that will come next.

This adds support for all the MachO *_command structures. The load_command payloads still are not represented, but that will come next.

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.

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.
