    …Geo#8967, 3.8.0 regression)
    
    m_abyWrkBuffer and m_abyWrkBufferMask were mistakenly put at the
    VRTComplexSource level, missing that there can be a big number of
    sources whose lifetime is the same as the VRT dataset, and thus it
    is inappropriate to have long-lived working buffers at that level.
    We can actually use one single instance of them for all sources, so
    move that at the dataset level.
