fix flush deadlock
...
This commit fixes a deadlock that occurs during b1 flushes. It's
caused by taking locks in a different order. In the flush, b1
locks the engine and then bolt. However, in the query cursor, a
lock is obtained on bolt first (via `DB.Begin()`) and then the
engine is locked while reading from the engine's cache.

protect engine points cache from concurrent modifications.

Creating a cursor would access the engine cache concurrently with
writes, causing data races. Fix by adding a mutex around cache

fix duplicate points in b1/cursor
...
This commit fixes the b1 cursor so that reads from either the cache
or bolt buffer will check against the previously read key to ensure
that two of the same keys are not returned.
Fixes #3571 .
