Pawel Jakub Dawidek f13942a746 - The geom(8) utility only uses three types of arguments: string (char *),
value (intmax_t) and boolean (int).
  Based on that provide three functions:
        - gctl_get_ascii()
        - gctl_get_int()
        - gctl_get_intmax()
- Hide gctl_get_param() function, as it is only used internally in
  subr.c.
- Allow to provide argument name as (fmt, ...).
- Assert geom(8) bugs (missing argument is a geom(8) bug).

- Clean-up and simplify the code by using new functions and assumtions
  (no more checking for missing argument).

Tested by:	regression tests
