- Resolve for lists that aren't constants, but that are SEF, and reference a constant element, e.g. llList2String([llGetKey(), 5], 1) -> 5.
- Make it work with invalid conversions, if they are SEF.
- Simplify invalid conversions when the list argument is a llGetObjectDetails call and SEF.
- Simplify llList2String(llGetObjectDetails(id, [single_element]), 0) (or -1) to (string)llGetObjectDetails...; same with llList2Key and llList2Integer, converting it to (integer)((string)llGetObjectDetails...).
- Add TODO item to do it similarly for llGet[Link]PrimitiveParams.
Adds auxiliary functions to return a node or constant from a list in any of its forms, its length, and a constant for a node or constant.
Adds some utility members for LSL<->Python type conversion (one of them duplicated from lslparse.py).
Needs maintenance of the types returned by llGetObjectDetails.
