Cardano Updates

Avoid tmp allocations in receivedTxIdsImpl by updating available/buffered
tx maps in one pass.

Avoid tmp allocations in acknowledgeTxIds by folding acknowledged txids once
for mempool queueing and refcount updates.

Avoid building temporary Maps and Sets in pickTxsToDownload and
filterActivePeers.

Merge countRejectedTxs and updateBufferedTx calls into the same atomic
operation so that submitTxsToMempool only bumps the generation number
once.

Cut down on the number of wakeups by only depending on the debouncer.

Move tx counter tracing to drainRejectionThread where it will be run at
most once per second.

If state change wait at most 25ms for additional changes in order to
coalece TX events together.

Send lists of TXs to the mempool when possible. This mimics the
behaviour of the V1 tx submission.

Use a generation counter to track changes to SharedStateVar and only
call the expensive makeDecisions if a timer has expired or the shared
state has changed.

- Updated `cardano-diffusion` (requires a revision in `CHaP`)
- Restricted `contra-tracer < 0.2` for `network-mux` (revision is
  already in `CHaP`).

* added export list to `Ouroboros.Network.Diffusion.Topology`
* re-xport it in `Cardano.Network.Diffusion.Topology

We are no longer exporting:

* `rootConfigToRelayAccessPoint`
* `localRootsToRelayAccessPoint`

These are not used in `cardano-node`.

filterActivePeers.
