47441f56dc Part 5: Push FindQuery into query-algebrizer; structure errors.
This is a big deck-chair re-arrangement.  This puts FindQuery into
query-algebrizer and puts the validation from ParsedFindQuery ->
FindQuery their as well.

Some tests were re-homed for this.

In addition, the little-used maplit crate dependency was replaced with
inline expressions.

3dc68bcd38 Combine NamespacedKeyword and Keyword. (#689) r=nalexander
* Make properties on NamespacedKeyword/NamespacedSymbol private

* Use only a single String for NamespacedKeyword/NamespacedSymbol

* Review comments.

* Remove unsafe code in namespaced_name.

Benchmarking shows approximately zero change.

* Allow the types of ns and name to differ when constructing a NamespacedName.

* Make symbol namespaces optional.

* Normalize names of keyword/symbol constructors.

This will make the subsequent refactor much less painful.

* Use expect not unwrap.

* Merge Keyword and NamespacedKeyword.

Closes #634 - Fix variables in predicates (#635) r=rnewman
We were forgetting to check for bound variables when resolving types other than ref types during inequality handling. This patch adds in the binding checks and `bails` if the bound variable is of the wrong type. #634

e33fe71c47 Rework caching and use it inside the query engine. (#553) r=emily
This puts caching in mentat_db, adds a reverse lookup capability for
unique attributes, and populates bidirectional caches with a single
SQL cursor walk.

Differentiate between begin_read and begin_uncached_read.

Note that we still allow toggling within InProgress, because there might be
transient local state that makes starting a new transaction impossible.
