Subject: [C++0x patch] clean up <future> slightly

	* include/std/future (unique_future::get, promise::set_value): Remove
	workaround for c++/34022.
	(packaged_task::get_future, packaged_task::operator()): Use
	__throw_bad_function_call.
	* testsuite/30_threads/packaged_task/cons/assign_neg.cc: Adjust.
	* testsuite/30_threads/packaged_task/cons/copy_neg.cc: Likewise.
	* testsuite/30_threads/promise/cons/assign_neg.cc: Likewise.
	* testsuite/30_threads/promise/cons/copy_neg.cc: Likewise.

Tested x86_64/Linux and committed.

The <future> header needs a lot of changes to bring it up to date with
the WP, this patch doesn't do that, but I hope to get it done for 4.5
