* Tidy chain Cargo.toml
* Organize imports
* Add method to get note commitments from all Actions in Orchard shielded data
* Add method to get note commitments from all JoinSplits in Sprout JoinSplitData
* Add Request and Response variants for awaiting anchors
* Add anchors and note commitment trees to finalized state db
* Add (From|Into)Disk impls for tree::Roots and stubs for NoteCommitmentTrees
* Track anchors and note commitment trees in Chain
Append note commitments to their trees when doing update_chain_state_with,
then use the resulting Sapling and Orchard roots to pass to history_tree, and add
new roots to the anchor sets.
* Handle errors when appending to note commitment trees
* Add comments explaining why note commitment are not removed from the tree in revert_chain_state_with
* Implementing note commitments in finalized state
* Finish serialization of Orchard tree; remove old tree when updating finalize state
* Add serialization and finalized state updates for Sprout and Sapling trees
* Partially handle trees in non-finalized state. Use Option for trees in Chain
* Rebuild trees when forking; change finalized state tree getters to not require height
* Pass empty trees to tests; use empty trees by default in Chain
* Also rebuild anchor sets when forking
* Use empty tree as default in finalized state tree getters (for now)
* Use HashMultiSet for anchors in order to make pop_root() work correctly
* Reduce DEFAULT_PARTIAL_CHAIN_PROPTEST_CASES and MAX_PARTIAL_CHAIN_BLOCKS
* Reduce DEFAULT_PARTIAL_CHAIN_PROPTEST_CASES and MAX_PARTIAL_CHAIN_BLOCKS even more
* Apply suggestions from code review
* Add comments about order of note commitments and related methods/fields
* Don't use Option for trees
* Set DEFAULT_PARTIAL_CHAIN_PROPTEST_CASES=1 and restore MAX_PARTIAL_CHAIN_BLOCKS
* Remove unneeded anchor set rebuilding in fork()
* Improve proptest formatting
* Add missing comparisons to eq_internal_state
* Renamed sprout::tree::NoteCommitmentTree::hash() to root()
* Improve comments
* Add asserts, add issues to TODOs
* Remove impl Default for Chain since it was only used by tests
* Improve documentation and assertions; add tree serialization tests
* Remove Sprout code, which will be moved to another branch
* Add todo! in Sprout tree append()
* Remove stub request, response *Anchor* handling for now
* Add test for validating Sapling note commitment tree using test blocks
* Increase database version (new columns added for note commitment trees and anchors)
* Update test to make sure the order of sapling_note_commitments() is being tested
* Improve comments and structure of the test
* Improve variable names again
* Rustfmt

* Move the preallocate tests into their own files
And move the MetaAddr proptest into its own file.
Also do some minor formatting and cleanups.

* 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
