* Adds a parameter to `zebra_consensus::router::init()` for accepting a mempool setup argument, adds and uses an `init_test()` fn for passing a closed channel receiver in tests where no mempool service is needed in the transaction verifier.
* Adds a `mempool` argument to the transaction::Verifier constructor (and a `new_for_tests()` constructor for convenience)
* Removes `Clone` impl on `transaction::Verifier` to add mempool oneshot receiver, updates tests.
* Adds TODOs
* updates transaction verifier's poll_ready() method to setup the mempool service handle.
* Updates VerifiedSet struct used in mempool storage
* Updates mempool service and its `Storage` to use the updated `VerifiedSet` `transactions()` return type.
* updates `created_outputs` when inserting or removing a transaction from the mempool's verified set
* Adds a TODO, updates field docs
* Updates `spent_utxos()` to query the mempool for unspent outputs
* Adds `spent_mempool_outpoints` as a field on tx verifier mempool response
* Updates mempool `Downloads` to return the spent_mempool_outpoints from the tx verifier response
* Updates `Storage.insert()` to accept a list of spent mempool transaction outputs
* Adds transaction dependencies when inserting a tx in `VerifiedSet`
* polls mempool svc from tx verifier when a mempool tx that creates transparent outputs has been verified.
adds a TODO for adding a `pending_outputs` field to the mempool Storage
* Adds `pending_outputs` field on mempool Storage and responds to pending outputs requests when inserting new transactions into the mempool's verified set
* replaces `UnminedTxId` type with `transaction::Hash` in mempool's verified set
* prune pending outputs when rejecting and removing same effects.
* Remove dependent transactions from verified set when removing a tx
* updates tests
* appeases clippy.
* removes unused `len()` method
* fixes doc links
* Adds transaction dependencies to the `FullTransactions` response, let the caller handle it (required to avoid moving zip317 tx selection code to mempool)
* updates block template construction to avoid including transactions unless their dependencies have already been added.
* updates tests
* Replaces placeholder setup channel with one that sends the mempool svc to the tx verifier, adds a timeout layer, adds a TODO about a concurrency bug
* Use a single query to check for unspent outputs in the mempool
* Updates `getblocktemplate` method to consider dependencies when sorting transactions for the final template
* fixes clippy lints, removes unnecessary Option in UnspentOutput response variant
* renames type alias and method, adds a TODO to use iteration instead of recursion
* Adds mempool_removes_dependent_transactions() test
* Updates Storage and VerifiedSet clear() methods to clear pending_outputs, created_outputs, and transaction_dependencies, adds TODO to use iteration instead of recursion.
* removes outdated TODO
* Adds a TODO for reporting queued transaction verification results from the mempool from the poll_ready() method
* Adds `mempool_responds_to_await_output` test
* updates mempool_responds_to_await_output test
* Uses iteration instead of recursion in verified set's remove() method and zip317 mod's dependencies_depth() method
* Adds a mempool_request_with_mempool_output_is_accepted test for the transaction verifier
* Moves delay duration before polling the mempool to a constant, uses a shorter timeout for mempool output lookups, adds a `poll_count` to MockService, and updates `mempool_request_with_unmined_output_spends_is_accepted` to check that the transaction verifier polls the mempool after verifying a mempool transaction with transparent outputs
* adds long_poll_input_mempool_tx_ids_are_sorted test
* Adds a `excludes_tx_with_unselected_dependencies` test
* Updates a TODO
* moves `TransactionDependencies` struct to `zebra-node-services`
* Updates `FullTransactions` response variant's `transaction_dependencies` type
* updates zip317 transaction selection for block templates to include dependent transactions
* Moves and refactors zip317 tx selection test to its own module, adds an `unmined_transactions_in_blocks()` method on network
* Removes `unmined_transactions_in_blocks()` test utility fn from mempool Storage test module and replaces calls to it with calls to the new test method on Network
* Fixes spelling mistake
* Adds `includes_tx_with_selected_dependencies` test
* fixes zip317 block construction issue
* Fixes vectors test
* Update zebra-node-services/src/mempool.rs
* restores `tip_rejected_exact` type
