Finally remove LibFunction.opcode

 - Change unpack to be indentical to table.unpack. Lua 5.1's unpack
   doesn't __len/__index (and so only works on tables, rather than
   userdata), but I don't think will break any existing code.

 - Make some of the platform code less flexible. This code only exists
   for passing the Lua tests really - we don't need it in CC, so no
   sense making it customisable.
