[PATCH] Implement DRs 60 and 63

[Pétur Runólfsson <peturr02 at ru dot is>]

This patch implements DR 63 (TC) and those parts of DR 60 (TC) that refer
to ostream manipulators and unformatted output functions.

I'm assuming that "does not behave as an [un]formatted output function"
in DR 60 means:

* Don't construct sentry objects
* Don't catch exceptions

Tested on i686-pc-linux-gnu.

	* include/bits/ostream.tcc
	(basic_ostream::operator<<(basic_ostream& (*)(basic_ostream&)),
	basic_ostream::operator<<(basic_ios& (*)(basic_ios&)),
	basic_ostream::operator<<(ios_base& (*)(ios_base&))):
	Implement the resolution of DR 60 (TC): These are not formatted
	output functions so don't construct sentry objects and don't
	catch exceptions.
	(basic_ostream::put, basic_ostream::write): Implement the
	resolution of DR 63 (TC) by catching exceptions and setting
	badbit.
	(basic_ostream::flush): Implement the resolution of DR 60 (TC):
	This is not an unformatted output function so don't construct
	a sentry object.
	* testsuite/testsuite_io.h (sync_streambuf): Define.
	* testsuite/27_io/basic_ostream/flush/char/2.cc: New test.
	* testsuite/27_io/basic_ostream/inserters_other/char/5.cc: New test.
	* testsuite/27_io/basic_ostream/put/char/1.cc: New test.
