Fix formatting

- Drop duplicate outgoing TMGetLedger messages per peer
  - Allow a retry after 30s in case of peer or network congestion.
  - Addresses RIPD-1870
  - (Changes levelization. That is not desirable, and will need to be fixed.)
- Drop duplicate incoming TMGetLedger messages per peer
  - Allow a retry after 15s in case of peer or network congestion.
  - The requestCookie is ignored when computing the hash, thus increasing
    the chances of detecting duplicate messages.
  - With duplicate messages, keep track of the different requestCookies
    (or lack of cookie). When work is finally done for a given request,
    send the response to all the peers that are waiting on the request,
    sending one message per peer, including all the cookies and
    a "directResponse" flag indicating the data is intended for the
    sender, too.
  - Addresses RIPD-1871
- Drop duplicate incoming TMLedgerData messages
  - Addresses RIPD-1869

+> To ensure, that lockfile creation works the same way on all developer machines, you should clear the local cache before creating a new lockfile.

 - **[Fast, Efficient Consensus Algorithm][]:** The XRP Ledger's consensus algorithm settles transactions in 4 to 5 seconds, processing at a throughput of up to 1500 transactions per second. These properties put XRP at least an order of magnitude ahead of other top digital assets.

The XRP Ledger can settle long, cross-currency payment paths and exchanges of multiple currencies in atomic transactions, bridging gaps of trust with XRP.

+ * as indicated by it's presence in a Collection.
+ *
+ * If the Item is not in the Collection, it will be added under lock in the
+ * ctor, and removed under lock in the dtor. The object will be considered
+ * "usable" and evaluate to `true`.
+ *
+ * If the Item is in the Collection, no changes will be made to the collection,
+ * and the CanProcess object will be considered "unusable".
+ *
+ * It's up to the caller to decide what "usable" and "unusable" mean. (e.g.
+ * Process or skip a block of code, or set a flag.)
+ *
+ * The current use is to avoid lock contention that would be involved in
+ * processing something associated with the Item.
+ *
+ * Examples:
+ *
+ * void IncomingLedgers::acquireAsync(LedgerHash const& hash, ...)
+ * {
+ *    if (CanProcess check{acquiresMutex_, pendingAcquires_, hash})
