Add common ammounts commitment lookup table
- Implements `compute_zero_commitment` function in `cuprate-helper::crypto` module.
- Added test that compare the function output with the correct calculation.
- Use of a constant-time algorithm for the lookup table.

* `database/` -> `storage/`, create skeleton `storage/` crates
* add skeleton root directories
* books: add skeleton
* ci: fix labeler.yml
* fix CONTRIBUTING.md
* fix workspace Cargo.toml
* fix `storage/`
* rename helper fs fn, `cuprate_database` -> `cuprate_blockchain`
* fix Cargo.toml
* cuprate-blockchain: revert find-and-replace
Since it has to be ported to the book anyway, there's not much
reason to update this and create review diffs.
* labeler.yml: remove `A-docs` from `books/` changes
Although books are documentation,
the `A-books` label already exists for this
* error: add `NeedsResize`
accidently removed, was `MapFull` before.
We need this because we as the writer thread must
react to this error in order to resize.
The writer thread doesn't have access to `heed::Error`, but
`Runtime::Error`, so this variant must exist
* env/backend: add `MANUAL_RESIZE` and `resize()`
* heed: respect `ReadersFull`, comment errors
* free: add `resize_memory_map()`
* env: add `Env::current_map_size`
* service: add `resize_map()`
* database: make `Env` itself cheaply clonable + threadsafe
`heed::Env` already uses `Arc` internally, but `sanakirja` does
not, so abstract this at the `Env` level instead of wrapping
`ConcreteEnv` in `Arc` ourselves.
* service: `Arc<ConcreteEnv>` -> `ConcreteEnv: Clone`
* env: add `SYNCS_PER_TX`, `path()`, `shutdown()`
* database: add `src/service/state.rs`
* service: add to `state.rs`, add `DatabaseState` to readers/writer
* add `parking_lot`
Okay, turns out we need to take locks in
`database/src/service/state.rs`...
`std`'s lock fairness policies are not well defined and
depend on the OS implementation, `parking_lot` on the other hand
has a fairness policy which is important when the writer needs
the lock but readers keep pouring in, essentially never letting
the writer do stuff.
* state: use `crossbeam::atomic::AtomicCell`
We have crossbeam as a dep anyway.
* heed: `heed::Env` -> `Arc<RwLock<heed::Env>>`
* service: add reader shutdown handle, use `Select` for msgs
* service: remove `state.rs`
We don't need this, we will represent shutdowns with channel
messages and `Select`, and mutual exclusion with a `RwLock`.
* service: fix misc reader/writer stuff
* database: add `config.rs`
* service: use `ReaderThreads` when spawning readers
* service: impl `shutdown()` for readers/writer
* service: return `DatabaseReaderReceivers` on shutdown via `JoinHandle`
Solves the issue of unfortunately timed `Request`s
that come in _right_ as we are shutting down.
If we (Cuprate) drop the database channels too early the requesting
thread will probably panic as they probably use `.unwrap()`,
never expecting a channel failure.
Returning this structure containing all the channels allows the
final shutdown code to carry these channels until the very end
of the program, at which point, all threads exit - no panics.
* remove `parking_lot`
Could be used as the database mutual exclusion lock.
Needs to be tested against `std`.
* config: add `path`
* env: `path()` -> `config()`, backend: impl `Drop`
* `Arc<ConcreteEnv>`, shutdown `service` on channel disconnect
* backend: add `Config` to `ConcreteEnv`
* service: use `std:🧵:Builder` for readers/writer
* config: `PathBuf` -> `Cow<'static, Path>`
* misc docs, remove `RuntimeError::ShuttingDown`
* service: init & shutdown docs
* heed: impl `Env::resize_map()`
* heed: impl `Env::current_map_size()`
* lib.rs: add example crate usage test
* heed: `RwLock` comment
* helper: add `cuprate_database_dir()`
* config: use `cuprate_database_dir()`
* lib.rs: TODO example test
* database: add `page_size`
The database memory map size must be a multiple of
the OS page size. Why doesn't `heed` re-expose this?
It calls it when checking anyway...
