Apply `(S)FtpPersistentAcceptOnceFileListFilter` for the `(S)FtpInboundFileSynchronizer` by default to avoid cases to sync the same remote files to the local directory again.
Especially when `localFileName` strategy is applied and we end up with new local files, but with the same remote content
Accept `(S)FtpPersistentAcceptOnceFileListFilter` for streaming adapters
Make `doSetFilter()` as `protected final`
Fix tests after rebase
Fix "What's New" after rebase
Compose `PersistentAcceptOnceFileListFilter` together with the regex or pattern filters
Document such a behavior
Address PR comments for formatting and typo
