I have a modified index2adr that allows range of pseudoindices to map to  
values in the
array part of the registry.
I have also modified copies of luaL_ref and luaL_unref that work only with  
the
registry, implicitly (no argument 't').

This is used by non-lua part of the code to implement references to Lua  
values,
and to have well-known indices to important values.
It also makes C part more readable, sometimes reducing number of Lua API  
calls
more than twice.
