* Add function hooks to mod symbol format * Add function sizes to section function tables * Add support for function hooks in live generator * Add an option to the context to force function lookup for all non-relocated function calls * Include relocs in overlay data * Include R_MIPS_26 relocs in symbol file dumping/parsing * Add manual patch symbols (syms.ld) to the output overlay file and relocs * Fix which relocs were being emitted for patch sections * Fix sign extension issue with mfc1, add TODO for banker's rounding
