patch 9.1.1063: too many strlen() calls in userfunc.c

Browse Source 
Problem:  too many strlen() calls in userfunc.c
Solution: refactor userfunc.c and remove calls to strlen(),
          drop set_ufunc_name() and roll it into alloc_ufunc(),
          check for out-of-memory condition in trans_function_name_ext()
