* makeint.h (MAP_USERFUNC): A new map type for function names.

* gnumake.h (gmk_func_ptr): Define a type for function pointers.
(gmk_add_function): Convert the last argument to FLAGS.

* function.c (function_table_entry): Use new function pointer type.
(lookup_function): Accept any valid function name character based
on the MAP_USERFUNC values.
(define_new_function): Use the new calling signature. Verify that
registered functions have valid names.
