Also "lua_tounsigned()" would be handy.

:)  imho, the whole integer support should be revised.

Anything else invoces undefined behaviour, and results in
daemons flying out of your nose.

lua_Integer is a typedef for ptrdiff_t, which must be signed. So for
safe extraction of unsigned integers in stock Lua there may be a need
for a lua_UnsignedInteger typedef, and a lua_tounsignedinteger function.
Maybe lua_Unsigned and lua_tounsigned would be clear enough.
