This is a follow up to my last two changes to the condition_variable
code.  For some reason G++ didn't reject the explicitly-defaulted
functions in src/condition_variable.cc even though they had different
exception specifications to the declaration.  I will try to file that
in bugzilla but can't yet reproduce it in a smaller testcase.  This
patch also removes the condition_variable_any::native_handle_type
typedef which is unused since I removed native_handle() in r180446, so
the testcase has to go too.

        * include/std/condition_variable (condition_variable_any): Remove
        unused native_handle_type typedef.
        * src/condition_variable.cc (condition_variable): Add missing noexcept
        specifications.
        * 30_threads/condition_variable_any/requirements/typedefs.cc: Remove.

Tested x86_64-linux, committed to trunk.
