Wladimir J. van der Laan b155130224 Merge #11476: Avoid opening copied wallet databases simultaneously
478a89c Avoid opening copied wallet databases simultaneously (Russell Yanofsky)

Pull request description:

  Make sure wallet databases have unique fileids. If they don't, throw an error. BDB caches do not work properly when more than one open database has the same fileid, because values written to one database may show up in reads to other databases.

  Bitcoin will never create different databases with the same fileid, but users can create them by manually copying database files.

  BDB caching bug was reported by @dooglus in https://github.com/bitcoin/bitcoin/issues/11429
