Kernel#inspect: improve consistency and do not call #to_s.

A class can now benefit from the nice default #inspect even if it
defines #to_s. Also, there is no more unexpected change in #inspect
result. Internal structures have been adapted so they don't rely
on the removed behavior (#inspect calling overridden #to_s).

* object.c (rb_obj_inspect): Kernel#inspect: do not call #to_s.
* test/ruby/test_object.rb (test_inspect): add tests for Kernel#inspect.
* bignum.c, io.c, numeric.c, object.c, proc.c, vm.c (Init_*):
  alias #inspect to #to_s where it was expected.
