* 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
* Rename constant to `MIN_INVENTORY_HASH_SIZE`
Because the size is not constant anymore, since the `MSG_WTX` inventory
type is larger.
* Add `InventoryHash::smallest_types_strategy`
A method for a proptest strategy that generates the `InventoryHash`
variants that have the smallest serialized size.
* Update proptest to use only smallest inventories
In order to properly test the maximum allocation.
* Add intra-doc links in some method documentation
Make it easier to navigate from the documentation of the proptest
strategies to the variants they generate.
* Parse `MSG_WTX` inventory type
Avoid returning an error if a received `GetData` or `Inv` message
contains a `MSG_WTX` inventory type. This prevents Zebra from
disconnecting from peers that announce V5 transactions.
* Fix inventory hash size proptest
The serialized size now depends on what type of `InventoryHash` is being
tested.
* Implement serialization of `InventoryHash::Wtx`
For now it just copies the stored bytes, in order to allow the tests to
run correctly.
* Test if `MSG_WTX` inventory is parsed correctly
Create some mock input bytes representing a serialized `MSG_WTX`
inventory item, and check that it can be deserialized successfully.
* Generate arbitrary `InventoryHash::Wtx` for tests
Create a strategy that only generates `InventoryHash::Wtx` instances,
and also update the `Arbitrary` implementation for `InventoryHash` to
also generate `Wtx` variants.
* Test `InventoryHash` serialization roundtrip
Given an arbitrary `InventoryHash`, check that it does not change after
being serialized and deserialized.
Currently, `InventoryHash::Wtx` can't be serialized, so this test will
is expected to panic for now, but it will fail once the serialization
code is implemented, and then the `should_panic` should be removed.
* Test deserialize `InventoryHash` from random bytes
Create an random input vector of bytes, and try to deserialize an
`InventoryHash` from it. This should either succeed or fail in an
expected way.
* Remove redundant attribute
The attribute is redundant because the `arbitrary` module already has
that attribute.
* Implement `Message::inv_strategy()`
A method to return a proptest strategy that creates `Message::Inv`
instances.
* Implement `Message::get_data_strategy()`
A method that returns a proptest strategy that creates
`Message::GetData` instances.
* Test encode/decode roundtrip of some `Message`s
Create a `Message` instance, encode it and then decode it using a
`Codec` instance and check that the result is the same as the initial
`Message`.
For now, this only tests `Message::Inv` and `Message::GetData`, because
these are the variants that are related to the scope of the current set
of changes to support parsing the `MSG_WTX` inventory type.
Even so, the test relies on being able to serialize an
`InventoryHash::Wtx`, which is currently not implemented. Therefore the
test was marked as `should_panic` until the serialization code is
implemented.
* Move the preallocate tests into their own files
And move the MetaAddr proptest into its own file.
Also do some minor formatting and cleanups.

* Implement SafePreallocate. Resolves#1880
* Add proptests for SafePreallocate
* Apply suggestions from code review
Comments which did not include replacement code will be addressed in a follow-up commit.

* Rename [Safe-> Trusted]Allocate. Add doc and tests
Add tests to show that the largest allowed vec under TrustedPreallocate
is small enough to fit in a Zcash block/message (depending on type).
Add doc comments to all TrustedPreallocate test cases.
Tighten bounds on max_trusted_alloc for some types.
Note - this commit does NOT include TrustedPreallocate
impls for JoinSplitData, String, and Script.
These impls will be added in a follow up commit

This is the first in a sequence of changes that change the block:: items
to not include Block as a prefix in their name, in accordance with the
Rust API guidelines.
Closes#158.
As discussed on the issue, this makes it possible to safely serialize
data into hashes, and encourages serializable data to make illegal
states unrepresentable.
