    Revert "typefind: Store caps on the pad before emitting have-type but send
it downstream only in the default signal handler"

    This reverts commit 0835c3d6569dde0ec9e5524436367c7678cc4a4a.

    It causes deadlocks in decodebin, which currently would deadlock if the
caps
    are already on the pad in have-type and are forwarded while copying the
sticky
    events (while holding the decodebin lock)... as that might cause the next
    element to expose pads, which then calls back into decodebin and takes the
    decodebin lock.

    This needs some more thoughts.
