Debug

We have forked the debug/ folder from the standard library, to take direct control of the debug/elf, debug/macho, and debug/pe binary format parsers. To these parsers, we have added the ability to also generate executable files from the parsed intermediate data structures. This lets us load a file with debug parsers, make changes by interacting with the parser structures, and then write those changes back out to a new file.

Relocation editing

• debug/elf: AddRelocation, AddRelocations, ReplaceRelocations, RemoveRelocations, AddRelocationForSymbol, AddRelocationForAddr, AddRelocationsToRelocSection, RemoveRelocationsFromRelocSection (alloc relocs can now grow via a new PT_LOAD when needed)
• debug/macho: AddRelocation, AddRelocations, ReplaceRelocations, RemoveRelocations, AddScatteredRelocation, AddRelocationForSymbol, AddRelocationForSymbolWithDylibOrdinal, SetDylibOrdinalForSymbol, SetBindKindForSymbol
• debug/pe: AddBaseRelocation, ReplaceBaseRelocations, RemoveBaseRelocations, AddBaseReloc, AddSectionRelocation, AddSectionRelocationForSymbol, ReplaceSectionRelocations, RemoveSectionRelocations
