Parse without copying; parse keyword maps using macros. This is a big commit, but it breaks into two conceptual pieces. The first is to "parse without copying". We replace a stream of an owned collection of edn::ValueAndSpan and instead have a stream of a borrowed collection of &edn::ValueAndSpan references. (Generally, this is represented as an iterator over a slice, but it can be over other things too.) Cloning such iterators is constant time, which improves on cloning an owned collection of edn::ValueAndSpan, which is linear time in the length of the collection and additional time depending on the complexity of the EDN values. The second conceptual piece is to parse keyword maps using a special parser and a macro to build the parser implementations. Before, we created a new edn::ValueAndSpan::Map to represent a keyword map in vector form; since we're working with &edn::ValueAndSpan references now, we can't create an &edn::ValueAndSpan reference with an appropriate lifetime. Therefore we generalize the concept of iteration slightly and turn keyword maps in map form into linear iterators by flattening the value maps. This is a potentially obscuring transformation, so we have to take care to protect against some failure cases. (See the comments and the tests in the code.) After these changes, parsing using `combine` is linear time (and reasonably fast).

Update some dependencies. (#492) r=etoop * Update some dependencies. * Update rusqlite to 0.12. * Update error-chain to a forked version that implements Sync. * Fix some compiler warnings. * Remove unused imports in tests. * Parse errors no longer naturally print with the expected symbol.

[dependencies.edn]
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.
