* ext/readline/readline.c (Init_readline): Use rl_hook_func_t instead
  of Function to support readline-6.3.  (rl_hook_func_t is available
  since readline-4.2.)
  Reported by Dmitry Medvinsky.  [ruby-core:61141] [Bug #9578]

* ext/readline/extconf.rb (rl_hook_func_t): define as Function for
  very old readline versions.  [ruby-core:61209] [Bug #9578]

* ext/readline/extconf.rb: fix typo, `$defs` not `$DEFS`.
