About branch begin-concurrent-pnu-wal2

Like the begin-concurrent-wal2 branch, this branch contains both the wal2 and "BEGIN CONCURRENT" enhancements. It also has:

  • the mutex-free PRNG,
  • the mutex-free shmlock enhancement for VFS unix-excl,
  • the "PRAGMA noop_update" feature (hence the "pnu" in the branch name), and
  • the sqlite3_wal_info() API.
