add(consensus): Adds `disable_pow` and `genesis_hash` fields, converts `equihash::Solution` to an enum (#8421)
* minor cleanup and rename

* Adds an empty NetworkParameters struct to Network::Testnet variant, updates production code.

* Updates tests

* Adds `NetworkKind` and uses it instead of `Network` in `HistoryTreeParts` and `transparent::Address`

* Adds a [network.testnet_parameters] section to the config, uses `NetworkKind` as zebra_network::Config::network field type, and converts 'Network' to `NetworkKind` before serializing

* Applies some suggestions from code review

* Applies suggestions from code review

* returns b58 prefix constants directly to remove From<NetworkKind> impl for zcash_primitives::consensus::Network

* Applies more suggestions from code review.

* moves conversions to zcash_primitives::consensus::Network to where they're used.

* Apply suggestions from code review

Co-authored-by: Marek <mail@marek.onl>

* rename `network` variables and method names typed as NetworkKind to `network_kind`

* use only test block heights for the network associated with them

* Applies more suggestions from code review.

* Rename `NetworkParameters` to `Parameters` and move it a new `testnet` module

* adds activation heights field

* updates stored test config, adds a quicker test for checking that stored configs can be parsed, adds an intermediate representation of activation heights

* implement Parameters for Network

* Passes &Network directly instead of converting to zp_consensus::Network where there were conversions

* fixes a bad merge (removes a network conversion in zcash_note_encryption)

* Adds a test for the Parameters impl for zebra_chain::Network

* fixes doc links

* - Makes the `activation_heights` config field optional by adding a #[serde(default)]
- Panics if a non-zero activation height is provided for the `Genesis` network upgrade
- Always sets the `Genesis` and `BeforeOverwinter` network upgrade activation heights to 0 and 1, `BeforeOverwinter` could be overwritten by a later network upgrade
- Makes the `activation_heights` field on `Parameters` private, adds/uses an accessor method instead, and adds a builder struct and `build()` method

* small refactor of activation_heights() method

* check that activation heights are in the right order

* Updates `NetworkUpgrade::activation_height()` to return the height of the next NetworkUpgrade if it doesn't find the activation height of `&self`

* checks that the miner address is of TestnetKind on Regtest and update assertion message

* Adds a DNetworkUpgradeActivationHeights struct for better control over how activation heights can be configured

* moves all ordered network upgrades to a constant, adds a no_duplicates test, moves struct with activation heights outside deserialization impl and accepts it in `ParametersBuilder::activation_heights()` instead of a Vec

* panics if any network upgrades are configured to activate at Height(0) because it's reserved for Genesis

* Simplifies the `ParametersBuilder::activation_heights()` method and removes an unnecessary test.

* Adds Sapling HRPs as fields on testnet params. (#8398)

* Applies suggestions from code review.

* Update zebra-chain/src/parameters/network_upgrade.rs

Co-authored-by: Marek <mail@marek.onl>

* Adds `network_name` field and accessor method on `Parameters`, uses it in the `Display` impl for `Network`

* Removes unnecessary `.filter()`

* adds constraints on valid network names and a test

* adds config field for setting network name, adds "with_" prefix to ParameterBuilder setter methods

* Adds `MainnetKind`, `TestnetKind`, and `RegtestKind` to reserved network names

* updates stored test configs and fixes `network_name()` docs

* Adds a `new_regtest()` method on `Network` and `testnet::Parameters`, updates config deserialization to return an error if the initial_testnet_peers include any default initial peers AND contain configured activation heights

* Updates `activates_network_upgrades_correctly` test to check Regtest activation heights (and default Mainnet/Testnet)

* Refactors if-let & match statement into general match statement, removes constraint against including `testnet_parameters` field/section in the config when using `Mainnet` or `Regtest`

* Removes outdated TODO

* Restores `testnet_parameters` section of the latest stored config.

* Adds `with_sapling_hrps()` method and uses it to set the Regtest HRPs in `new_regtest()`.

Adds a test for Sapling HRP validation

* Checks that default Mainnet/Testnet/Regtest Sapling HRPs pass validation in `with_sapling_hrps()`

* Uses the correct constant in test

* Adds `is_regtest()` methods

* Adds genesis hash methods and fields to `testnet::Parameters` and its builder

* Copies Regtest genesis block from zcashd

* moves genesis hash check to Network.checkpoint_list()

* Checks the first line in the checkpoint list instead of the first item in the BTreeMap

* Checks that there is _some_ genesis block in the checkpoints list in `from_list()`, adds Regtest checkpoints (which only includes the genesis block)

* Adds a doc comment to `ParametersBuilder::default()`

* Adds a `disable_pow` field and skips checking proof of work if it's true

* Makes `equihash::Solution` an enum to support Regtest solutions, adds a test for validating and committing the Regtest genesis block

* use genesis_hash as first checkpoint when checkpoints are missing for configured testnets too

* Applies suggestions from code review.

* Reverts changes to `activation_height()` method

* Avoids panic in test

* Updates test docs

* drop custom panic hooks after expected panics

change(scan): Refactor scanning tests (#8047)
* Derive & impl helper traits from `std`

* Create `compact_to_v4` fn

* Create `fake_block` fn

* Refactor existing tests to use the new functions

* Cosmetics

* Refactor docs

* Put `Default` behind `cfg_attr(test)`

Rationale
---------

We avoid implementing `Default` on consensus-critical types because it's
easy to miss an incorrect use in a review. It's easy to hide a
`default()` in a call like `unwrap_or_default()` or even more subtle
methods.

Security: reject compact sizes greater than the protocol message limit (#2155)

teor b2a9ea62fe Round-trip the PoWLimit through the compact representation
`zcashd` converts the PoWLimit into a compact representation before
using it to perform difficulty filter checks.

The Zcash specification converts to compact for the default difficulty
filter, but not for testnet minimum difficulty blocks. (ZIP 205 and
ZIP 208 don't specify this conversion either.) See #1277.
