    CompositeTask: handle SIGINT/TERM cancelled futures (bug 657436)
    
    In order to avoid raising an unwanted CancelledError, make
    CompositeTask check for cancelled futures before attempting
    to call future.result(). The intention is only to handle
    failures triggered by SIGINT/TERM, since other types of
    expected failures should always be handled by catching the
    exception raised from future.result().

    _unlock_builddir_exit: fix cancel/returncode interaction
    
    When the _unlock_builddir_exit returncode parameter has not been
    specified, do not attempt to cancel the current task, since the
    task has already completed. This mirrors logic added to the
    Binpkg _unlock_builddir_exit method in the previous commit.

    sys-apps/portage: fix Ctrl-C CancelledError regression (bug 657436)
    
    Fix an annoying regression involving a CancelledError exception raised
    during Ctrl-C interrupt handling. Also include the small patch for
    bug 657420. Remove the sed call that applied commit d07a47ff3c06 for
    bug 656942, and apply the fix using a patch instead.
