Improvements in 'luaL_traceback'

'luaL_traceback' changed to use an aux buffer instead of concats.
This should reduce the quantity of garbage it generates (in the
form of intermediate strings) while producing a trackback.
It also added information about the number of levels skipped when
skipping levels in a trace.
