Nick Alexander dcd9bcb1ce Extract partial storage abstraction; use error-chain throughout. Fixes #328. r=rnewman (#341)
* Pre: Drop unneeded tx0 from search results.

* Pre: Don't require a schema in some of the DB code.

The idea is to separate the transaction applying code, which is
schema-aware, from the concrete storage code, which is just concerned
with getting bits onto disk.

* Pre: Only reference Schema, not DB, in debug module.

This is part of a larger separation of the volatile PartitionMap,
which is modified every transaction, from the stable Schema, which is
infrequently modified.

* Pre: Fix indentation.

* Extract part of DB to new SchemaTypeChecking trait.

* Extract part of DB to new PartitionMapping trait.

* Pre: Don't expect :db.part/tx partition to advance when tx fails.

This fails right now, because we allocate tx IDs even when we shouldn't.

* Sketch a db interface without DB.

* Add ValueParseError; use error-chain in tx-parser.

This can be simplified when
https://github.com/Marwes/combine/issues/86 makes it to a published
release, but this unblocks us for now.  This converts the `combine`
error type `ParseError<&'a [edn::Value]>` to a type with owned
`Vec<edn::Value>` collections, re-using `edn::Value::Vector` for
making them `Display`.

* Pre: Accept Borrow<Schema> instead of just &Schema in debug module.

This makes it easy to use Rc<Schema> or Arc<Schema> without inserting
&* sigils throughout the code.

* Use error-chain in query-parser.

There are a few things to point out here:

- the fine grained error types have been flattened into one crate-wide
  error type; it's pretty easy to regain the granularity as needed.

- edn::ParseError is automatically lifted to
  mentat_query_parser::errors::Error;

- we use mentat_parser_utils::ValueParser to maintain parsing error
  information from `combine`.

* Patch up top-level.

* Review comment: Only `borrow()` once.
