Tested x86_64-linux, pushed to trunk.

This adds required headers to a few internal headers that currently
assume their deps will be included first. It's more robust to make them
include their own dependencies, so that later refactoring or reuse of
those headers in new contexts doesn't break.
libstdc++-v3/ChangeLog:
* include/bits/stl_algo.h: Include <bits/stl_algobase.h>.
* include/bits/stl_tempbuf.h: Include headers for __try and
__catch macros, std::pair, and __gnu_cxx::__numeric_traits.
* include/bits/stream_iterator.h: Include <iosfwd> and headers
for std::addressof and std::iterator.
* include/bits/streambuf_iterator.h: Include header for
std::iterator.
* include/std/iterator: Do not include <iosfwd>.
