Finish preliminary wchar_t implementation, with trivial encodings.

	Finish preliminary wchar_t implementation, with trivial encodings.
	* docs/configopts.html: Add bits about canonical configure option
	checking.

	* testsuite/27_io/iostream_objects.cc: Replace this file (which
	has newly-declared-illegal mixing of wide/narrow stdstreams) with...
	* testsuite/27_io/narrow_stream_objects.cc: New file.
	* testsuite/27_io/wide_stream_objects.cc: New file.

	* bits/fstream.tcc (underflow): Temporarily hack a solution
	together that writes from the external file to the internal
	buffers. This removes codecvt from the loop, and is incorrect.
	(_M_really_overflow): Same here.

	* testsuite/21_strings/inserters_extractors.cc (test05): Tweaks.
