* Redesign Sapling data model for V5 shared anchor and spends
The shared anchor is only present if there are any spends.
As part of this change, delete the manual PartialEq impl and its tests,
because we can derive PartialEq now.
* Stop creating a temporary Vec for the spend and output iterators
* Rename TransferData variants
Interactive rename using the following commands:
```sh
fastmod Spends SpendsAndMaybeOutputs
fastmod NoSpends JustOutputs
```
* Refactor out common sprout nullifier code
* Implement the AtLeastOne constrained vector type
This vector wrapper ensures that it always contains at least one element.
* Simplify Sapling TransferData using AtLeastOne
Also update the RFC to use AtLeastOne for Orchard.
* 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.

* 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
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

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.
