206af35e2b release 0.8.0 
- major refactoring to the database APIs for safer parallel
  processing (#78, #82):
  - To set an input, you now write `db.query_mut(Query).set(...)`,
    and you must declare your database as `mut`.
  - To fork a thread, you now write `db.snapshot()`, which acquires
    a read-lock that is only released when the snapshot is dropped
    (note that this read-lock blocks `set` from occuring on the main
    thread).
  - Therefore, there can only be one mutable handle to the
    database; all other handles are snapshots. This eliminates a variety
    of complex and error-prone usage patterns.
- introduced the `salsa_event` callback that can be used for logging
  and introspection (#63)

5a88871b9a improve snapshot docs 
Using two snapshots from the same thread isn't really very easy to do,
so we don't have to warn about that really (it's really nested use of
snapshots that's a problem, and to do that you have to use thread-locals
or something just to get the snapshot *into* the database -- at that
point, something is really going wrong)).

Changes:
- correct dead locks and add parallel stress test (#72)
- we now panic if you `get` an input that has not been `set` and
  we do not compare inputs for equality (thus dropped `Default` and `Eq`
  bounds) (#69)
- `PanicGuard` now detects internal salsa bugs (#71)
