Instead of creating a block locator all the way back to the genesis
block, only ask for blocks within the reorg limit (99 blocks).
Use the reorg limit as the final locator. (Or if the chain is less
than 99 blocks, use the genesis block.)
Fixes some instances of #818 at very small block heights.
The state service was providing block locators starting at the parent of
the current tip. Instead, include the current tip in the block locator.
Also handle an edge case where we could include the genesis block twice,
if the current tip height was a power of two.
Fixes an instance of #818 where we re-download the current tip.
* Load tracing filter only from config and simplify logic.
* Configure the state storage in the config, not an environment variable.
This also changes the config so that the path is always set rather than being
optional, because Zebra always needs a place to store its config.
* add zebrad acceptance tests
* add custom command test helpers that work with kill
* add and use info event for start and seed commands
* combine conflicting tests into one test case

* temp: use cleaner error handling example
* add ability to test only for presence of error
We had a brief discussion on discord and it seemed like we had consensus on the
following versioning policy:
* zebrad: match major version to NU version, so we will start by releasing
zebrad 3.0.0;
* zebra-* libraries: start by matching zebrad's version, then increment major
versions of each library as we need to make breaking changes (potentially
faster than the zebrad version, always respecting semver but making no
guarantees about the longevity of major releases).
This commit sets all of the crate versions to 3.0.0-alpha.0 -- the -alpha.0
marks it as a prerelease not subject to perfect adherence to compatibility
guarantees.
Only hash block headers in the lowest-level block index code.
This design has a few benefits:
- failures are obvious, because the hash is not available,
- get_tip() returns a smaller object,
- we avoid re-hashing block headers multiple times.
These efficiency changes may be needed to support chain reorganisations,
multiple tips, and heavy query loads.
Move block header hashing from zebra-consensus to zebra-state.
Handle zebra-state AddBlock errors in zebra-consensus BlockVerifier.
Add unit tests for BlockVerifier state error handling.
Part of #428.
* rename zebra-storage to zebra-state
* Setup initial skeleton for zebra-state
* add test
* Apply suggestions from code review
