The proposed patch adds context manager support aifc module. Now objects returned by aifc.open() will support context manager protocol.

This issue required first fixing bpo-16485 to pass tests.

[birkenfeld]

The "self.fout.close()" is not needed here I think.

Another thing the test should test is that the file was actually closed on exception.

Otherwise, LGTM.

[serhiy-storchaka]

fout.close() here is intentional no-op. This is a check that fout was closed properly (in contrary case close() should raise exception). Unfortunately there is no other way to test that fout was closed.

Issue bpo-16486: Make aifc files work with 'with' as context managers.

[serhiy-storchaka]

I have added the test that the file was actually closed using external file (as in test_close()).
