d419554361 Revert "Add Datomic, for testing."
This reverts commit 1b1cc6f18e.

This should never have escaped the lab; Datomic is not a dependency of
Datomish.

71446a3af5 Completely rewrite main transaction logic to be faster.
This is almost complete; it passes the test suite save for retracting
fulltext datoms correctly.

There's a lot to say about this approach, but I don't have time to give
too many details.  The broad outline is as follows.  We collect datoms
to add and retract in a tx_lookup table.  Depending on flags ("search
value" sv and "search value type tag" svalue_type_tag) we "complete" the
tx_lookup table by joining matching datoms.  This allows us to find
datoms that are present (and should not be added as part of the
transaction, or should be retracted as part of the transaction, or
should be replaced as part of the transaction.  We complete the
tx_lookup (in place!) in two separate INSERTs to avoid a quadratic
two-table walk (explain the queries to observe that both INSERTs walk
the lookup table once and then use the datoms indexes to complete the
matching values).

We could simplify the code by using multiple lookup tables, both for the
two cases of search parameters (eav vs. ea) and for the incomplete and
completed rows.  Right now we differentiate the former with NULL checks,
and the latter by incrementing the added0 column.  It performs well
enough, so I haven't tried to understand the performance of separating
these things.

After the tx_lookup table is completed, we build the transaction from
it; and update the datoms materialized view table as well.  Observe the
careful handling of the "search value" sv parameters to handle replacing
:db.cardinality/one datoms.

Finally, we read the processed transaction back to produce to the API.
This is strictly to match the Datomic API; we might make allow to skip
this, since many consumers will not want to stream this over the wire.

Rough timings show the transactor processing a single >50k datom
transaction in about 3.5s, of which less than 0.5s is spent in the
expensive joins.  Further, repeating the processing of the same
transaction is only about 3.5s again!  That's the worst possible for the
joins, since every single inserted datom will already be present in the
database, making the most expensive join match every row.

cca5010671 Part 1: Fix testing errors.
Some of these were just typos, but `with-open` was fatally flawed on
CLJS (we couldn't call `.close` at all), and `deftest-async` was hiding
all failures (due to a typo).

d5cfbeaa45 Add tempfile and with-tempfile to CLJS.
We already have a nice library like this for CLJ (tempfile); this builds
the same thing for CLJS, using Node.js's tmp.

0a312b4f40 Add an async and async testing framework.
This is a well-worn idea: use a `promise-channel` of `[result nil]` or
`[nil error]` pairs.  The `go-pair` and `<?` macros handle catching
exceptions (important, given that synchronous CLJ code expects to throw
rather than return an error promise or similar), allowing code like:
```
(go-pair
  (let [result (<? (pair-chan-fn))]
    (when (not result)
      (throw (Exception. "No result!")))
    (transform result)))
```
to be expressed naturally.  These are the equivalents of `async` and
`await` in JS.

The implementation is complicated by significant incompatibilities
between CLJ and CLJS.  The solution presented here takes care to
separate the macro definitions into CLJ.  Sadly, this requires
namespacing the per-environment symbols explicitly; but we hope to
minimize such code in files like this.

The most significant restriction to this approach is that consumers must
require the transitive dependencies of the macro-defining modules.  See
the included tests (both CLJ and CLJS) for the appropriate
incantations (for pair-chan, core.async, and test).
