Avoid opening copied wallet databases simultaneously
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.
