Function settraps

lib/lua/src/ldebug.c:114–118

** Set 'trap' for all active Lua frames. ** This function can be called during a signal, under "reasonable" ** assumptions. A new 'ci' is completely linked in the list before it ** becomes part of the "active" list, and we assume that pointers are ** atomic; see comment in next function. ** (A compiler doing interprocedural optimizations could, theoretically, ** reorder memory writes in such a way

** has no good reasons to do that.)
