Export setter and getter for pointer checking print procedures

Direct access to GC_same_obj_print_proc, GC_is_visible_print_proc
and GC_is_valid_displacement_print_proc is now deprecated.

* include/gc/gc.h (GC_same_obj_print_proc,
GC_is_valid_displacement_print_proc, GC_is_visible_print_proc): Move
the declaration upper (to be right after GC_get_finalizer_notifier);
improve comment; add GC_ATTR_DEPRECATED attribute.
* include/gc/gc.h (GC_valid_ptr_print_proc_t,
GC_same_obj_print_proc_t): New public type.
* include/gc/gc.h (GC_same_obj_print_proc): Use
GC_same_obj_print_proc_t type.
* ptr_chck.c (GC_same_obj_print_proc): Likewise.
* include/gc/gc.h (GC_is_valid_displacement_print_proc,
GC_is_visible_print_proc): Use GC_valid_ptr_print_proc_t type.
* ptr_chck.c (GC_is_valid_displacement_print_proc,
GC_is_visible_print_proc): Likewise.
* include/gc/gc.h (GC_set_same_obj_print_proc,
GC_get_same_obj_print_proc, GC_set_is_valid_displacement_print_proc,
GC_get_is_valid_displacement_print_proc, GC_set_is_visible_print_proc,
GC_get_is_visible_print_proc): New public function declaration.
* ptr_chck.c (GC_set_same_obj_print_proc,
GC_get_same_obj_print_proc, GC_set_is_valid_displacement_print_proc,
GC_get_is_valid_displacement_print_proc, GC_set_is_visible_print_proc,
GC_get_is_visible_print_proc): New function definition.
* tests/gctest.c [!DBG_HDRS_ALL] (set_print_procs): Use
GC_set_is_valid_displacement_print_proc() and
GC_set_is_visible_print_proc() instead of setting
GC_is_valid_displacement_print_proc and GC_set_is_visible_print_proc
variables.
* tests/gctest.c [GC_PTHREADS] (main): Call
GC_get_is_valid_displacement_print_proc(),
GC_get_is_visible_print_proc(), GC_get_same_obj_print_proc() and
GC_set_same_obj_print_proc().
