report_errors now return an object of type test_report, which currently contains the number of failed tests. In the future, it may be extended with more additional data, if the need appears.
test_report can be converted to int, which is used to return a 0 or 1 from main. This preserves the canonical use case return boost::report_errors(); ate the end of main.
test_report allows to obtain the actual number of failed tests via error_count(), so to test if the number of failed tests is as expected, use return boost::report_errors().error_count() == expected ? 0 : 1; construct.
test_report prohibits comparison against integers to catch the previously broken tests using the return boost::report_errors() == expected; pattern. Not only the comparison result was wrong, the returned value from main was the opposite from normal.
An additional function get_error_count() is provided to obtain the current number of errors at any point.
