    libstdc++: Update documentation about copyright and GPL notices in tests
    
    There is no need to require FSF copyright for tests that are just
    "self-evident" ways to check the API and behaviour of the library.
    This is consistent with tests for the compiler, which do not have
    copyright and licence notices either.
    
    libstdc++-v3/ChangeLog:
    
            * doc/xml/manual/test.xml: Remove requirement for copyright and
            GPL notice in tests.
            * doc/html/manual/test.html: Regenerate.
