Fix several calls that had wraparound hazards.

llGetSubString("abc", 3, -1) gives "abc"; llList2List(L, 1, -1) gives L when L has length 1. In general, llGetSubString or llList2List return the whole thing when the starting index is grater than the last element in the list.

There were a number of spots with that hazard, so fix all we found.
