    Revert "qtdemux: Always snap to the start of the keyframe"

    This reverts commit 107902ec514bd826aa29d2298107e2c091e1c779.

    This commit intended to ensure that keyframe seeks land at the
    start timestamp of a keyframe, rather than in the middle of one,
    but they cause trouble on files with sparse streams, or with
    JPEG 'cover art' tracks that have only one or a few JPEG samples
    with very long durations.

    That's still desirable for doing seamless cutting of videos,
    but needs a rethink for implementation.

Leaving the bug open, because just reverting that commit breaks the seamless
cutting use case.
