    libc/db: Sync with FreeBSD
    
    - libc/db/hash: cap auto-tuned block size with a value that actually
      works
    - Consider flag == 0 as the same of flag == R_NEXT
    - Minor changes from Berkeley DB 1.86 and further improvements from
      OpenBSD
    - Allow O_SYNC and O_NOFOLLOW flags in dbopen()
    - Plug memory leaks and a potential NULL dereference
    - Simplify the logic when determining whether to zero out a db file to
      after open().
    - When deleting a big key, the offset of an empty page should be bsize,
      not bsize-1
    - Avoid overwriting the cursor page when the cursor page becomes the LRU
      page.
    - Fix for sequential retrieval failure when using large key/data pairs.
    - Fix a crash when iterating over a hash and removing its elements.
    - Only squeeze a short key/value pair onto a page with other complete
      key/value pairs
    - Return meaningful errno in overflow case
    - Save errno before calling _close(), which may clear it
    - Explicitly specify bit width for on-disk data structure.
