    Fix uploader-notification, credit awards, download-counters in FTP downloads

    Since v3.19 (the new filebases), when a user FTP-downloaded a file, we failed to properly find/load that file's record from the filebase (searching for the file's full path, rather than just the filename), so the code the increments the file's download counter, notifies the uploader, awards credits, etc. did not ever execute. This means that FTP-downloads for all files downloaded via FTP were effectively "free" (and nobody noticed). No error was logged either.

    I discovered this while debugging the case of "(null)" filenames in the action/download MQTT topic messages being published by the FTP server. So
    that issue is fixed as part of this commit as well.

    Oh, and if this code had executed before, it would have memory-leaked the
    file information, so that's fixed too (added call to smb_freefilemem). Ugh.

    ... not before. This explains why FTP-uploaded actions had a (null) filename. ---

    Limit uploaded file sizes, accounting for free disk space

    The lower of the configured maximum file size (for the FTP server) and
    the available disk space minus the configured minimum free disk space
    is used as the maximum file size to allow upload. Appended files
    are accounted for too.

    Fix false "SUSPECTED BOUNCE ATTACK ATTEMPT" for IPv6 FTP-data connections

    This bug only impacted non-passive FTP connections. Using an FTP client
    with active (not passive) data connections over an IPv6 connection would false-trigger the "bounce attack" detection and the FTP server responded with "504 Bad port number" and logged a hack attempt in data/hack.log.

    The issue was that we were comparing the socket address structure (which contains other fields besides the address itself) between the control and proposed-data connections. While this logic worked okay for IPv4,
    it did not for IPv6 (the 2 structs contained some non-address differences). Rather than modify the socket address structures to match where needed, I'm just comparing the string representation of the addresses, since that's
    what we really care about anyway.

    Thank to "mark i" of Truck Stop BBS for alerting me to this issue

    I observed an FTP client abuser getting a lot of logged warnings

    and these thread-shared pointers seemed suspicious. They probably should be converted to atomic bools.
