Failed build with latest LuaJIT #21
Description
Inside de97b9d, Mike added the implementation of API luaL_setfuncs(). Unfortunately, this causes lua-cjson build to fail because of redefinition of luaL_setfuncs().

Since there is no obvious macro we can use to test this change, I propose we use #ifdef luaL_newlibtable which was added as part of the same commit. I can confirm no other OpenResty project is defining luaL_newlibtable symbol and thus it should do the trick.
PR coming shortly.
