    Log Message:
    Detect TLS startup errors correct/fully

    We can't (apparently) only rely on the return value of start_tls(), we have to check the value of the crypt session too.
    This fix the possibility of this happening:
    Jun 7 18:07:26 sbbs synchronet: ftp 0058 TLS ERROR 'No permiss.to perform this operation' (-21) opening keyset
    Jun 7 18:07:26 sbbs synchronet: ftp 0058 <192.168.1.25> initialized TLS successfully

    Instead, we'll detect the failure and disable FTPS support, logging "failed to initialize TLS successfully".

    Fix segfault reported with ftpalias.cfg support in some cases

    ftpalias() can return true even when the directory is not set to a valid directory index (i.e. set to -1), so using as an array index would definitely segfault. Part of commit 8ad30b6c by Deuce 3 years ago.

    I didn't test this as I'm not sure exactly the combination of ftpalias.cfg content and FTP command received that would trigger this, but it's most definitely a bug.

    So should fix the segfault reported in issue #288.

    Fix FTPS upload failure: !DATA ERROR 0 receiving on data socket

    Don't treat CRYPT_ERROR_COMPLETE (-24) as a socket error during upload since it's an indication that the remote closed the connection and is the normal "end of file/transfer" indicator, not an error. 'rd' is already 0 in this case, so no need to set at all (since recv() returns 0 upon disconnect and that's what we're emulating here).

    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.

    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

    Restore ftpalias.cfg support for MLSx commands

    Support was accidentally removed as part of commit 0d01544d, meaning
    the ftpalias.cfg wasn't used at all in responses to the MLSx commands as reported by Max (WESTLINE) using Total Commander, FileZilla and Directory
    opus. The traditional "LIST" commands still worked fine with ftpalias.cfg contents just fine.

    The reason this code was accidentally removed was due to the errant
    copy/pasted comparison with startup->html_index_file that did not belong here and made the block appear related to HTML index file generation. It was not. This was just a bug in the initial implementation of MLSx support in
    commit d4deb4b3.

    Also included in this commit:
    - Return the date/size of the user's QWK packet file, if it exists, in MLSx
    response.
    - send_mlsx_entry() won't report negative time_t values as file modify dates
    (flength returns -1 upon failure/file-not-found).
    - get_owner_name() returns the string, making it easier to use in function
    calls.

    There appears to still be some work to do to make the MLSx commands fully compliant with RFC 3659 (e.g. "mlst filename" from ftpalias.cfg should work
    but does not), but at least FileZilla displays ftpalias.cfg files and directories correctly now.
