dqlite v1.16.5
Significant changes in this release:
- dqlite now uses file locking to ensure that two nodes don't run concurrently using the same data directory (#656).
- The minimum required version of libuv has been increased to 1.34 (#617).
This release also includes smaller bug fixes, plus new code (not yet enabled) related to the future move to storing databases and WALs on disk.
