Don't validate an option in gen_mod:get*opt() functions

Browse source 
The changes are very similar to those from previous commit:
* Now there is no need to pass validating function in
  gen_mod:get_opt() and gen_mod:get_module_opt() functions,
  because the modules' configuration keeps already validated values.
* New functions gen_mod:get_opt/2 and gen_mod:get_module_opt/3 are
  introduced.
* Functions gen_mod:get_opt/4 and get_module_opt/5 are deprecated.
  If the functions are still called, the "function" argument is
  simply ignored.
* Validating callback Mod:listen_opt_type/1 is introduced to validate
  listening options at startup.
