* Run large checkpoint sync tests in CI
* Improve test child output match error context
* Add a debug_stop_at_height config
* Use stop at height in acceptance tests
And add some restart acceptance tests, to make sure the stop at
height feature works correctly.
## Motivation
The zebra-state service needs to be able to handle duplicate blocks.
## Solution
This implements changes already outlined by [The State
RFC](https://zebra.zfnd.org/dev/rfcs/0005-state-updates.html). We check for
successfully committed blocks first, since interacting with the queued blocks
struct at this point just complicates the implimentation. If the block has not
already been committed we then check if the block has already been queued, if
not we handle the block normally (normally here being the bit we already had
implemented).
## Documentation Changes
- [x] Update the state RFC to match the ways this fix departs from the design
- the main thing is that I switched the order of checking for duplicates
- [x] ~~Add newly added functions to the state rfc~~ Decided not to do this because they're minor getters that don't influence the rest of the design and aren't exposed as part of the API
- [x] Document newly added functions inline

We already use an actor model for the state service, so we get an
ordered sequence of state queries by message-passing. Instead of
performing reads in the futures we return, this commit performs them
synchronously. This means that all sled access is done from the same
task, which
(1) might reduce contention
(2) allows us to avoid using sled transactions when writing to the
state.

There's no reason to return a pre-Buffer'd service (there's no need for
internal access to the state service, as in zebra-network), but wrapping
it internally removes control of the buffer size from the caller.
This commit begins the process of integrating `zcash_script` with the rest of the system for verifying scripts while syncing the block chain. It does so by adding the necessary support for looking up UTXOs from the state service and implements the first parts of the `script::Verifier` for looking up the necessary UTXOs in the state and then generating the necessary call to `zcash_script` to verify the script itself.

This addresses at least three pain points:
- we were affected by bugs that were already fixed in git, but not in
the released crate;
- we can use service combinators to transform requests and responses;
- we can use the hedge middleware.
The version in git is still marked as 0.3.1 but these changes will be
part of tower 0.4: https://github.com/tower-rs/tower/issues/431
Using a Buffer with size 1 is a footgun because it allows only one
sender to call poll_ready at a time. This is usually undesirable
because it means that a task or service that calls poll_ready but only
makes a service call later (potentially much later) will block all other
callers.
The previous code filled in block height 0 for a missing coinbase height
in `SledState::commit_finalized`, since the genesis block is the only
block without a coinbase height (because of a mistake when it was
created).
However, @teor2345 noticed that this is incorrect, because we already
parse the genesis block specially and fill in its coinbase height
correctly. So instead, we can .expect it to be present, because we can
assume that all finalized blocks are valid.
The new `StateService` type wraps a `SledState` and a `MemoryState`.
This will allow the sled-related code and the in-memory code to be kept
separate, with the top-level `StateService` making method calls to one
or the other, as appropriate.
This commit removes the existing Service impl for the SledService. This
saves time in refactoring, and the code needs to be rewritten
anyways so there's no loss to deleting it now.
* Remove in-memory state service
* make the config compatible with toml again
* checkpoint commit to see how much I still have to revert
* back to the starting point...
* remove unused dependency
* reorganize error handling a bit
* need to make a new color-eyre release now
* reorder again because I have problems
* remove unnecessary helpers
* revert changes to config loading
* add back missing space
* Switch to released color-eyre version
* add back missing newline again...
* improve error message on unix when terminated by signal
* add context to last few asserts in acceptance tests
* instrument some of the helpers
* remove accidental extra space
* try to make this compile on windows
* reorg platform specific code
* hide on_disk module and fix broken link
Fixes a race condition between the height and hash tree updates, when
they are executed simultaneously with GetDepth. `get_tip` uses the height
tree, but `get` uses the hash tree.
This is the first in a sequence of changes that change the block:: items
to not include Block as a prefix in their name, in accordance with the
Rust API guidelines.
