* Stub `sendrawtransaction` RPC method
Register the RPC method, and stub an implementation that currently just
panics. The method has a single `String` parameter with the hexadecimal
string of the raw transaction's bytes and returns a
`SentTransactionHash` wrapper type that's just a hexadecimal `String` of
the sent transaction's hash.
* Add mempool service instance to `RpcImpl`
Use a type parameter to represent the mempool service using the
interface defined by `zebra-node-services`.
* Update test vector to use a mock mempool service
Update the test to be compatible with the changes to `RpcImpl`. The mock
mempool service is expected to not be used during the test.
* Use a `tower::Buffer` for the mempool service
Make it simpler to send requests to the service in a concurrent manner.
* Return a `Future` from `send_raw_transaction`
Make the call asynchronous.
* Implement `sendrawtransaction` RPC
Deserialize the transaction and send it to be queued for verification
and subsequent inclusion in the mempool.
* Test if mempool receives sent raw transaction
Use a mock service as the mempool service and check that it receives a
sent raw transaction.
* Test using non-hexadecimal string parameter
The method should return an error.
* Test with bytes that fail deserialization
Check that the method returns an invalid parameters error if the input
can't be deserialized as a `Transaction`.
* Test if mempool errors are forwarded to caller
Mempool service errors should be sent back to the remote caller as
server errors.
* Test transactions rejected by the mempool service
Transactions that are rejected by the mempool service should result in
a server error being sent to the caller.
* Improve error message
Add the word "structurally" to make it clear that the issue is in the
transaction's deserialization.

* Add note regarding missing `allowhighfees` param.
The parameter isn't supported yet because `lightwalletd` doesn't use it.
* Update the documentation to be consistent
Follow the convention adopted by the `get_info` RPC method.
* Implement `ToHex` and `FromHex` for `Hash`
Make it easier to generate hexadecimal strings from `transaction::Hash`
instances.
* Use `ToHex` in `Debug` and `Display`
Reduce repeated code.
* Refactor to add `bytes_in_display_order` method
Use it to remove repeated code and improve clarity a bit.
* Use `hex::serialize` to serialize transaction hash
Make the type stricter in its contents, while still serializing the
transaction has as a hexadecimal string.
* Simplify serialization attribute
Deserialization should also use `hex::deserialize`, so using the shorter
attribute makes things easier to read and more future proof.
* Update zebra-chain/src/transaction/hash.rs
* Remove unnecessary lifetime
The anonymous lifetime is automatically inferred by the compiler.

* Add `Arc<Transaction>` conversions for Transaction IDs
* Use UnminedTxId as the transaction verifier response type
* Use UnminedTx in transaction verifier mempool requests
* Refactor is_mempool into a transaction verifier request method
* Order derives in alphabetical order

* Rename internal network requests for wide transaction IDs
fastmod TransactionsByHash TransactionsById zebra*
fastmod AdvertiseTransactions AdvertiseTransactionIds zebra*
fastmod MempoolTransactions MempoolTransactionIds zebra*
fastmod TransactionHashes TransactionIds zebra*
* Update network transaction request/response comments
* Rename a transaction hash method for wide transaction IDs
fastmod transaction_hashes transaction_ids zebra-network
* Add UnminedTxId methods and conversions for InventoryHash
* Map WtxIds to unmined transaction network messages
Also, use UnminedTxId and UnminedTx in:
* Zebra's internal request and response format, and
* external Zcash network protocol messages.
* Enable WtxId mempool inventory tracking for peers
* Further clarify transaction IDs
* Use Witnessed rather than Wide for transaction IDs
And rename narrow to legacy when it only applies to v1-v4 transactions.
Otherwise, rename it to mined ID.
* Rename a missed binding
* Remove an incorrectly named binding

* Make the `AuthDigest` display order match transaction IDs
And derive `Hash`, just like transaction IDs.
Don't derive `serde` for now, because it's not needed.
* Move transaction::Hash test to tests module
* Add a simple AuthDigest display order test
* Add a WtxId type for wide transaction IDs
* Add conversions between transaction IDs and bytes
* Use the WtxId type in external network protocol messages
* Reverse displayed endianness of transaction and block hashes
* fix zebra-checkpoints utility for new hash order
* Stop using "zebrad revhex" in zebrad-hash-lookup
* Rebuild checkpoint lists in new hash order
This change also adds additional checkpoints to the end of each list.
* Replace TransactionHash with transaction::Hash
This change should have been made in #905, but we missed Debug impls
and some docs.

This extracts the SHA256d code from being split across two modules and puts it
in one module, under serialization.
The code is unchanged except for three deleted tests:
* `sha256d_flush` in `sha256d_writer` (not a meaningful test);
* `transactionhash_debug` (constructs an invalid transaction hash, and the
behavior is tested in the next test);
* `decode_state_debug` (we do not need to test the Debug output of
DecodeState);
* Added a few more top-level fields for the Transaction struct
* Add a placeholder Script type.
This could alternately use bytes::Bytes to save some allocations
but I don't think this is important to get perfectly now. In the future, we
will want to have all of the script handling code in the zebra-script crate,
but we will need to have a container type for an encoded script in zebra-chain,
because otherwise zebra-chain would depend on zebra-script and not the other
way around.
* Rename Transaction{Input,Output} -> Transparent{Input,Output}.
These are only *transparent* inputs and outputs, so by putting Transparent in
the name (instead of Transaction) it's more clear that a transaction's inputs
or outputs can also be shielded.
* Add a LockTime enum.
* First attempt at a Transaction enum.
This attempts to map the versioning and field presence rules into an ADT, so
that structurally invalid transactions (e.g., a BCTV14 proof in a Sapling
transaction) are unrepresentable.
* Update zebra-chain/src/transaction.rs

* Add fixme note on type refinement.
* Rename Transaction variants according to version.
* Split transaction.rs into submodules.
* Start filling in spend, output descriptions.
* Progress on JoinSplit data structures.
This has a lot of duplication and should really use generics to abstract over
Sprout-on-BCTV14 or Sprout-on-Groth16.
* Add data types for Bctv14 and Groth16 proofs.
This also adds a trait to abstract over them.
* Make JoinSplit descriptions generic over the proof system.
* Update zebra-chain/src/transaction/joinsplit.rs
