    Fix issue with failure to run reconciliation with all accounts present
    in a multi-account OFX file.
    Do that by saving a GList of statements, rather than a pointer to a single one.
    Also freeing of info happens during the call to process_next_file.

    Import of OFX files with many securities opens too many matching dialogs
    Because ofx import is currently split per target account, and since each security has its own accounts, importing such OFX is a tedious process.
    The fix is to only split the transactions if we identify a potential transfer, currently based on amount, date and accounts.
    To do that, we insert transactions one by one into a list, making sure we have not already inserted one that has the same date, and the same absolute amount. If we have, we keep this potential transfer for a second phase.
    A naive approach would loop through added transactions for each new transaction by that ends up being O(N^2), which matters if we have many transactions. Instead, I'm using a hash to make this O(N log N).
