afafcd64a0 [tx] Start implementing bulk SQL insertion algorithms (#214). r=rnewman,jsantell
* Pre: Add some value conversion tests.

This is follow-up to earlier work.  Turn TypedValue::Keyword into
edn::Value::NamespacedKeyword.  Don't take a reference to
value_type_tag.

* Pre: Add repeat_values.

Requires itertools, so this commit is not stand-alone.

* Pre: Expose the first transaction ID as bootstrap::TX0.

This is handy for testing.

* Pre: Improve debug module.

* Pre: Bump rusqlite version for https://github.com/jgallagher/rusqlite/issues/211.

* Pre: Use itertools.

* Start implementing bulk SQL insertion algorithms. (#214)

This is slightly simpler re-expression of the existing Clojure
implementation.

* Post: Start generic data-driven transaction testing. (#188)

* Review comment: `use ::{SYMBOL}` instead of `use {SYMBOL}`.

* Review comment: Prefer bindings_per_statement to values_per_statement.

81af295948 Start installing SQL schema. (#171) r=rnewman
* Start installing the SQLite store and bootstrapping the datom store.

* Review comment: Decomplect V2_IDENTS.

* Review comment: Decomplect V2_PARTS.

* Review comment: Pre: Expose Clojure's merge on Value instances.

* Review comment: Decomplect V2_SYMBOLIC_SCHEMA.

* Review comment: Decomplect V1_STATEMENTS.

* Review comment: Prefer ? to try!.

* Review comment: Fix typos; format; add TODOs.

* Review comment: Assert that Mentat `Schema` is valid upon creation.

* Review comment: Improve conversion to and from SQL values.

This patch factors the fundamental SQL conversion maps
between (rusqlite::Value, value_type_tag) and (edn::Value, ValueType)
through a new Mentat TypedValue.  (A future patch might rename this
fundamental type mentat::Value.)

To make certain conversion functions infallible, I removed
placeholders for :db.type/{instant,uuid,uri}.  (We could panic
instead, but there's no need to do that right now.)

* Review comment: Always uses bundled SQLite in rusqlite.

This avoids (runtime) failures in Travis CI due to old SQLite
versions.  See 432966ac77.

* Review comment: Move semantics in `from_sql_value_pair`.

* Review comment: DB_EXCISE_BEFORE_T instead of ...BEFORET (no underscore).

* Review comment: Move overview notes to the Wiki.
