Implement Sapling serialization in Transaction V5 (#2020)
* serialize/deserialize spaling shielded data in v5 transaction

* fix serialize/deserialize fields order according to spec

* remove extra clone calls

* more serialize fixes

* clippy: fix empty array

* tidy comments

* Add v4 and v5 transaction tests

Also make sure that serialized bytes match if structs match.

* Test fake v5 blocks made out of pre-NU5 block test vectors

* Add outputs-only tests for v5 shared anchor serialization

* Refactor sapling::ShieldedData V5 serialization into its own impl

* Fix spec name typos

* Simplify sapling shielded data parsing

* Delete redundant V5 transaction wrappers in tests

And split out sapling ShieldedData serialization.

Redesign Transaction V5 serialization, impl trusted vector security, nullifier utility functions (#1996)
* add sapling shielded data to transaction V5

* implement nullifiers

* test v5 in shielded_data_roundtrip

* Explicitly design serialization for Transaction V5

Implement serialization for V4 and V5 spends and outputs, to make sure
that the design works.

* Test serialization for v5 spends and outputs

Also add a few missing v4 tests.

* Delete a disabled proptest

* Make v5 transactions a top-level heading

And add a missing serialized type.

* Fix a comment typo

* v5 transaction RFC: split array serialization

Based on #2017

* RFC: explicitly describe serialized field order

And link to the spec

* RFC: add the shared anchor serialization rule test

Move the preallocate tests into their own files (#1977)
* 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 Trusted Vector Preallocation (#1920)
* 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.

Co-authored-by: teor <teor@riseup.net>

* 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

Refactor Sapling data and use it in V4 (#1946)
* start refactoring transaction v4 for transaction v5
- move ShieldedData to sapling
- add AnchorVariant
- rename shielded_data to sapling_shielded data in V4
- move value_balance into ShieldedData
- update prop tests for new structure

* add AnchorVariant to Spend
- make anchor types available from sapling crate
- update serialize

* change shielded_balances_match() arguments
* change variable name anchor to shared_anchor in ShieldedData
* fix empty value balance serialization
* use AnchorV in shielded spends
* Rename anchor to per_spend_anchor

* Use nullifiers function directly in non-finalized state
* Use self.value_balance instead of passing it as an argument

* Add missing fields to ShieldedData PartialEq
* Derive Copy for tag types

* Add doc comments for ShieldedData refactor
* Implement a per-spend anchor compatibility iterator

Henry de Valence 1fc859d0c5 chain: move Spend, Output into sapling
The ShieldedData container for the spend and output descriptions of a
transaction does *not* move, because it's encoding transaction
structure.  A good sign that this is the right factoring is that the
transaction module now only needs to pull in sapling::{Spend, Output}
and not all the internals.
