* add value balances to non finalized state
* fix 2 tests
* fix remaining constrain issues in tests
* extend value pool test to non finalized
* WIP: fix tests after adding value pools to non-finalized state (#2647)
* Update Chain::eq_internal_state with Chain.value_balance
Also increase the number of cases in its tests,
because they didn't detect this bug.
* Calculate the chain value pool change before `Chain::push`
Code
- store the chain value pool change in `ContextuallyValidBlock`
- convert `PreparedBlock` to `ContextuallyValidBlock` using `with_block_and_spent_utxos`
(rather than `from` or `into`)
- replace `block_utxos` with `new_outputs` in `PreparedBlock`
- replace `block_utxos` with `chain_value_pool_change` in `ContextuallyValidBlock`
Tests
- create test methods for `PreparedBlock` and `ContextuallyValidBlock`
- use `test_with_zero_chain_pool_change` or `test_with_zero_spent_utxos`
to make tests pass
* fix conflicts
* build `set_current_value_pool()` only for tests
* remove redundant cfgs
* change cfg of set_current_value_pool()
* Clarify some chain field documentation
* Fix bugs in the non-finalized chain value pool calculations
1. Only revert the chain value pool balances when the tip is popped.
Don't modify them when the root is finalized.
2. Only update or revert the chain value pool balances once per block.
(Previously, the block changes were multiplied by the number of *transactions*.)
And make corresponding changes to method names and documentation.
* Add extra proptests to try to identify value balance failures
* Simplify some transaction generation code
* Add extra debugging info to value balance errors
* Actually update non-finalized chain value pools in `UpdateWith`
Previously, we were dropping the updated value pools in the `Ok` result.
So the initial (finalized) chain value pool balances were never modified.
* Rename and document value balance add methods
The names and documentation of these methods were confusing.
* Create genesis-based proptests that check chain value pools
* Increase coverage for some test vectors
* Test each chain value balance calculation for blocks 0-10
* Make continuous blockchain test errors easier to debug
* Test the exact transparent pool values for the first few blocks

* Validate transparent coinbase output maturity and shielding
- Add a CoinbaseSpendRestriction enum and Transaction method
- Validate transparent coinbase spends in non-finalized chains
* Don't use genesis created UTXOs for spends in generated block chains
* Refactor out a new_transaction_ordered_outputs function
* Add Transaction::outputs_mut for tests
* Generate valid transparent spends in arbitrary block chains
* When generating blocks, fixup the block contents, then the block hash
* Test that generated chains contain at least one transparent spend
* Make generated chains long enough for reliable tests
* Add transparent and shielded input and output methods to Transaction
* Split chain generation into 3 functions
* Test that unshielded and immature transparent coinbase spends fail
* Comment punctuation
* Clarify a comment
* Clarify probability calculation
* Test that shielded mature coinbase output spends succeed
* Add `proptest-impl` feature to `zebra-state`
This prepares the `zebra-state` crate to be able to export some
test-specific helper types and functions.
* Add `arbitrary` module to `zebra-state` root
A separate module to contain the `Prepare` trait, since it's required by
some prop-test strategies and therefore can't be in the `tests` module.
* Replace usages of `tests::Prepare`
Use the same trait but placed in a new module that's accessible based on
the feature flag.
* Remove old `Prepare` trait
It was obsoleted by the new copy in the `arbitrary` module.
* Make `StateService` crate-accessible
Prepare for it to be accessible in some test modules.
* Refactor strategy function import
Import the function directly, instead of just its containing module.
* Move some strategy functions to `tests::setup`
Create a new module for the strategy functions that are only used
internally.
