    basesink: when draining, deep copy the last buffer to unref old memory

    Use gst_buffer_copy_deep() to force the copy of the underlying
    memory instead of possibly doing a shallow copy of the buffer
    and just referencing the memory

    gstbuffer: add gst_buffer_copy_deep

    A variant of gst_buffer_copy that forces the underlying memory
    to be copied.

    This is added to avoid adding an extra reference to a GstMemory
    that might belong to a bufferpool that is trying to be drained.
    The use case is when the buffer copying is done to release the
    old buffer and all its resources.
