cff49b6df5 Initialize the sqlite connection with WAL and foreign keys. 
This somewhat improves performance, which is nice.

f4344fa28a Bump JVM stack size to 4MB and eliminate tiered compilation. 
This allows CLJS compilation to complete for complex go-pair forms.

See <https://github.com/emezeske/lein-cljsbuild/issues/303> for more details.

c948902c52 Follow-up: Extract datomish.transact.explode. 
This required pushing the ID literal out of transact.  I elected to put
them in DB, since literal allocation will end up in IDB eventually.

d8c976c3ad Follow-up: split the monolith! 
This was a little more tricky than might be expected because the
initialization process uses the transactor to bootstrap the database.
Since Clojure doesn't accept mutually recursive modules, this
necessitated a third module, namely "db-factory", which uses both "db"
and "transact".  While I was here, I started an "api" module, to paper
over the potentially complicated internal module structure for external
consumers.  In time, this "api" module may also grow CLJS-specific JS
transformations.

d9a8cb0d6a Don't accept user-provided tx values. 
This agrees with Datomic.  DataScript allows tx values, possibly to
allow reconstructing DBs from Datom streams, but appears to handle
user-provided tx values in the transactor inconsistently.

38545f6efc Add :tx and :txInstant to TxReport; accept :db/tx in transactor; allow to set :db/txInstant. 
The implementation of :db/tx is special and may need to change over
time.  We add it as a special ident, with value the current transaction
entity ID, specified per-transaction.  This works well right now but
introduces some (internal) ordering requirements that may need to be
loosened.

f25838a1eb Support :db/fulltext true. 
Internally, we use SQLite's FTS4 to maintain a fulltext_values table of
unique "text" values.  Fulltext indexed datoms have value v that is the
rowid into fulltext_values.  We manually maintain the map between rowid
and value in the transactor.

For convenience, we expose two views interpolating the real text values
into the datoms structure.

9497d69b44 Respect :db/unique constraints; test upserts. 
This version includes SQLite-level unique indexes; these should never be
needed.  I've included them as a fail-safe while testing; they'll help
us catch errors in the transaction layer above.

7a90c43a5a Map valueTypes to SQLite encodings.
