make nested iterator typedefs private in debug mode

It's "accepts implementation-defined" not "accepts invalid" - and it's
obviously by design that GCC accepts its own implementation-defined constructs!

This patch makes the typedefs inaccessible in debug mode and fixes up a couple
of functions that refer to them directly, rather than through iterator_traits.

Tested x86_64/linux. I also tried testing with -D_GLIBCXX_DEBUG added to
testsuite_flags but got lots of spurious failures that I don't think are
related to this change (as with parallel mode testing, all the
23_containers/*/synopsis.cc tests fail in debug mode - I haven't investigated
why)
