# Description of Changes
The first commit defines a type `TableName` that is used in e.g.,
`TxData` and where determined profitable and necessary to do this
change.
`TableName` is backed by
[`ecow::EcoString`](https://docs.rs/ecow/0.2.6/ecow/string/struct.EcoString.html)
which affords O(1) clones and 15 bytes of inline storage and
`mem::size_of::<EcoString>() == 16`.
The second commit does the same for `ReducerName`. This is also used in
reducer execution.
Together, these commits increase TPS by around 5-7k TPS.

# Testing
Covered by existing tests.
The `Clone` impl for `ClientConnection` would create an independent
instance that could not observe module hotswapping. This would result in
methods called on a replaced `ModuleHost` to fail, because that host
exited already.
Fix by reading the `ModuleHost` from the watch channel directly, instead
of maintaining a redundant copy.
Also fix `watch_module_host` to properly mark the current module host as
seen.

This patch attempts to integrate the new commitlog with the minimum
changes.
Most of the diff comes from deletions of the legacy log and the need to
adjust tests due to the requirement for a tokio runtime when a durable
database is used in tests.
The "meat" of the patch are the `RelationalDB` constructors,
`RelationalDB::commit_tx`, and the replay logic in
`locking_tx_datastore`.
While `DataKey` is gone, there is still some redundant data being passed
around, which will be addressed in the follow-up patch.
- Move it and friends from sats to vm.
- MemTable now stores a Vec<PV>.
- Other related improvements.
