4fd5880a0b Initialize the sqlite connection with WAL and foreign keys. 
This somewhat improves performance, which is nice.

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.
