Basic sync support (#563) r=nalexander
* Pre: remove remnants of 'open_empty'

* Pre: Cleanup 'datoms' table after a timeline move

Since timeline move operations use a transactor, they generate a
"phantom" 'tx' and a 'txInstant' assertion. It is "phantom" in a sense
that it was never present in the 'transactions' table, and is entirely
synthetic as far as our database is concerned.
It's an implementational artifact, and we were not cleaning it up.

It becomes a problem when we start inserting transactions after a move.
Once the transactor clashes with the phantom 'tx', it will retract the
phantom 'txInstant' value, leaving the transactions log in an incorrect state.

This patch adds a test for this scenario and elects the easy way out: simply
remove the offending 'txInstant' datom.

* Part 1: Sync without support for side-effects

A "side-effect" is defined here as a mutation of a remote state as part
of the sync.

If, during a sync we determine that a remote state needs to be changed, bail out.

This generally supports different variations of "baton-passing" syncing, where clients
will succeed syncing if each change is non-conflicting.

* Part 2: Support basic "side-effects" syncing

This patch introduces a concept of a follow-up sync. If a sync generated
a "merge transaction" (a regular transaction that contains assertions
necessary for local and remote transaction logs to converge), then
this transaction needs to be uploaded in a follow-up sync.

Generated SyncReport indicates if a follow-up sync is required.

Follow-up sync itself is just a regular sync. If remote state did not change,
it will result in a simple RemoteFastForward. Otherwise, we'll continue
merging and requesting a follow-up.

Schema alterations are explicitly not supported.

As local transactions are rebased on top of remote, following changes happen:
- entids are changed into tempids, letting transactor upsert :db/unique values
- entids for retractions are changed into lookup-refs if we're confident they'll succeed
-- otherwise, retractions are dropped on the floor

* Post: use a macro for more readable tests

22b17a6779 Split "mentat transaction" logic away from the main crate
Sync needs to operate over a "mentat transaction", not just a "db transaction".
This shuffle allows internal mentat crates to consume InProgress, which models
the concept of a "mentat transaction".

0b84a0802d Pre: Remove open_empty.
This was a work-around for Tolstoy, which couldn't gracefully handle
syncing a store with a bootstrap transaction.  Tolstoy now handles
that single transaction, so this is no longer necessary.

5976869b0a Post: Make tests pass on Rust 1.25.0
For some reason, the converted doc test fails on Rust 1.25.0, while
working with other Rust versions. For simplicity, just convert it into
a regular test.

4325d6c0c3 [sdks/android] Move main Mentat Android SDK tests from androidTest to test.
This leverages JNA to test the Android SDK on the host machine using
Robolectric, which is significantly faster and easier to debug than
the equivalent on-device instrumentation tests.

We'll still want instrumentation smoke tests, but they won't need to
cover the entire range of the Android SDK.
