Idea seems good. How about moving this into our actual LuaJ sources? |

Sure. Would you also like me to rebuild the LuaJ jar then? |

…mputerCraft ComputerCraft has an incomplete bit32 API. bit32.lib.lua implemented ALL the functions in software, but only if bit32 didn't exist entirely, which does on CC. This means bit32.extract and bit32.replace weren't implemented in software on CC. This commit fixes the issue. See dan200/ComputerCraft#298

This removes CC's
bitlibrary and adds LuaJ's implementation ofbit32, stubbing the originalbitlibrary. This has several advantages:bit32functions are significantly faster - my rather ad-hoc profiling shows a gain of somewhere between 1.5x and 2x.bit32now accepts variadic arguments and implementsextractandreplace.I realise you lose the nice abstraction of
ILuaAPI, but I don't feel that is a great loss -bitwon't be needed should we ever switch to Lua 5.2/5.3 anyway.I'm happy to move this to the LuaJ directory and rebuild the LuaJ jar should you want.
