    Don't keep full headers in memory during transaction
    The open/close file callbacks only need NEVRA information in the "key".
    Copy the necessary bits into a regular dict and pass that instead
    of the entire header, the callback wont even know the difference
    as the header behaves like a dict.
    Saves (tens of) megabytes of memory on large transactions.
