* Remove redundant documentation
The documentation was exactly the same as the documentation from the
trait.
* Calculate a mock time block delta for tests
Simulate a block being added to the chain with a random block time based
on the previous block time and the target spacing time.
* Add a `time` field to `ChainTipBlock`
Store the block time so that it's ready for a future chain that allows
obtaining the chain tip's block time.
* Add `ChainTip::best_tip_block_time` method
Allow obtaining the bes chain tip's block time.
* Add method to obtain both height and block time
Prevent any data races by returning both values so that they refer to
the same chain tip.
* Add `NetworkUpgrade::all_target_spacings` method
Returns all the target spacings defined for a network.
* Create a `NetworkChainTipEstimator` helper type
Isolate the code to calculate the height estimation in a new type, so
that it's easier to understand and doesn't decrease the readability of
the `chain_tip.rs` file.
* Add `ChainTip::estimate_network_chain_tip_height`
This is more of an extension method than a trait method. It uses the
`NetworkChainTipHeightEstimator` to actually perform the estimation, but
obtains the initial information from the current best chain tip.
* Fix typo in documentation
There was an extra closing bracket in the summary line.
* Refactor `MockChainTipSender` into a separate type
Prepare to allow mocking the block time of the best tip as well as the
block height.
* Allow sending mock best tip block times
Add a separate `watch` channel to send the best tip block times from a
`MockChainTipSender` to a `MockChainTip`.
The `best_tip_height_and_block_time` implementation will only return a
value if there's a height and a block time value for the best tip.
* Fix off-by-one height estimation error
Use Euclidean division to force the division result to round down
instead of rounding towards zero. This fixes an off-by-one error when
estimating a height that is lower than the current height, because the
fractionary result was being discarded, and it should have forced the
height to go one block back.
* Fix panics on local times very far in the past
Detect situations that might cause the block height estimate to
underflow, and return the genesis height instead.
* Fix another off-by-one height estimation error
The implementation of `chrono::Duration::num_seconds` adds one to the
number of seconds if it's negative. This breaks the division
calculation, so it has to be compensated for.
* Test network chain tip height estimation
Generate pairs of block heights and check that it's possible to estimate
the larger height from the smaller height and a displaced time
difference.
* Refactor so that RetryLimit::Future is std::marker::Sync
* Make the syncer future std::marker::Send by spawning tips futures
* Download synced blocks in chain order, not HashSet order
* Improve MockService failure messages
* Add closure-based responses to the MockService API
* Move MockChainTip to zebra-chain
* Add a MockChainTipSender type alias
* Support MockChainTip in ChainSync and its downloader
* Add syncer tests for obtain tips, extend tips, and wrong block hashes
* Add block too high tests for obtain tips and extend tips
* Add syncer tests for duplicate FindBlocks response hashes
* Allow longer request delays for mocked services in syncer tests
* Rename ChainTipReceiver to CurrentChainTip
`fastmod ChainTipReceiver CurrentChainTip zebra*`
* Update chain tip documentation and variable names
* Basic chain tip change implementation, without resets
Also includes the following name changes:
```
fastmod CurrentChainTip LatestChainTip zebra*
fastmod chain_tip_receiver latest_chain_tip zebra*
```
* Clarify the difference between `LatestChainTip` and `ChainTipChange`
* Store precalculated transactions in an `Arc`
Transaction `Hash`es are 32 bytes,
and the minimun transparent transaction size is 54 bytes.
So a full 2MB block can create 1.1MB of transaction hashes.
We use an `Arc` to avoid repeatedly cloning that much data.
* Remove the unused `Block` from `ChainTipBlock`
This drops the block as soon as it isn't needed any more.
Previously, it would stick around until every `ChainTipReceiver`
dropped their `ChainTipBlock`, even if they didn't use the `Block`
at all.
* Re-use finalized blocks for chain tip updates
This avoids serializing and deserializing blocks from the finalized state.
* Optimise tip sender equality checks
* Re-use precalculated block hashes and heights for chain tip updates
* Add chain tip mined transaction IDs
* Doc comment typo

* Always prefer the non-finalized tip in ChainTipSender
This significantly simplifies the internal implementation of ChainTipSender.
Also make the methods and types a bit more generic.
* Update ChainTipSender with blocks, not heights
Also fix a bug where queued non-finalized blocks would clear the chain tip.
* Provide a best tip hash in ChainTip receivers
* Skip finalized blocks once the non-finalized state is active
* Add tip hash and NoChainTip tests
* Remove a redundant finalized tip update
* Skip `None` updates to the finalized tip
The finalized and non-finalized tips never update to `None`
once they have added at least one block.
* Stop committing finalized queued blocks if there is an error
Also return the highest committed queued block.

* Rename BestTipHeight so it can be generalised to ChainTipSender
`fastmod BestTipHeight ChainTipSender zebra*`
For senders:
`fastmod best_tip_height chain_tip_sender zebra*`
For receivers:
`fastmod best_tip_height chain_tip_receiver zebra*`
* Rename best_tip_height module to chain_tip
* Wrap the chain tip watch channel in a ChainTipReceiver type
* Create a ChainTip trait to avoid tricky crate dependencies
And add convenience impls for optional and empty chain tips.
* Use the ChainTip trait in zebra-network
* Replace `Option<ChainTip>` with `NoChainTip`
