* 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.

* Reject transparent output double-spends

* Add a comment
* Clarify a consensus rule implementation

Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com>
* Further simplify and fix the UTXO check
- split each error case into a separate check
- combine `contains` and `insert`
- add a missing check against the non-finalized unspent UTXOs
- rename arguments and edit error strings for clarity
* Share test methods between check test modules
* Make some chain fields available to tests
* Make error field names consistent with transparent::Input
* WIP: Add tests for UTXO double-spends
- accept output and spend in the same block
- accept output and spend in a later block
- reject output and double-spend all in the same block
- reject output then double-spend in a later block
- reject output, spend, then double-spend all in different blocks
* Use Extend rather than multiple pushes
Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com>
* Use Extend for more pushes
* Limit the number of proptest cases, to speed up tests
* Test rejection of UTXOs that were never in the chain
* Test rejection of spends of later transactions in the same block
