* Uses `atomic_write_to_tmp_file` to write database versions to disk
* Removes `spawn_atomic_write_to_tmp_file()` and inlines its body at its callsite to avoid adding tokio as a dependency of zebra-chain.

* Always activate Canopy at Height(1) on Regtest
* Ignores the zip 212 grace period on configured Testnets and Regtest
* - Returns early when there is no Heartwood activation height when creating or updating HistoryTree
- Skips call to `check::legacy_chain()` when no NU5 activation height is set (it would return immediately anyway)
- Replaces `.map()` with `.filter_map()` in `NetworkUpgrade::target_spacings()`
- Removes outdated TODO
* - When proof of work is disabled, skips checking if Zebra is synced to the network tip in the getblocktemplate method
* Sets full_verifier_utxo_lookahead to Height::MIN instead of panicking
* When network is regtest, skips starting sync task and commits the genesis block if it's missing in the state
* updates/fixes test config
* Adds test for committing Canopy blocks on Regtest
* - Updates median time past and difficulty checks to use fewer than 11/17/28 blocks
* uses SLOW_START_INTERVAL of 0 if PoW is disabled, adds TODOs
* Update getblocktemplate method to return reserved chain history activation root hash, uses Nu5 at height 1
Test passes.
* Updates test to expect NU5 as the default nu activation at Height(1)
* Removes invalid difficulty snapshot
* fixes tests
* removes regtest NU5 activation height config field

* Use full paths for types from `zcash_primitives`
Upcoming commits will use `zcash_protocol::consensus::Parameters`, which
would make names such as `zp_consensus::Parameters` ambiguous since such
a name could stand for both `zcash_primitives...` and
`zcash_protocol...`.
* Impl and use conversion between network kinds
These conversions will make implementing
`zcash_protocol::consensus::Parameters` for `Network` easier.
* Impl conversions between network upgrades
* Impl `zcash_protocol::consensus::Parameters`
* Move `mod address` from under the gbt feature
* Remove a redundant `impl From`
* Impl `From` for a reference type correctly
The previous implementation called `into` on a reference without
dereferencing it. I thought the compiler would implicitly dereference,
but it didn't, which lead to infinite recursion since the fn ended up
calling itself.
* 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
