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.

The lower of the configured maximum file size (for the FTP server) and

is used as the maximum file size to allow upload. Appended files

Log Message:
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

Modified Files:
src/sbbs3/ftpsrvr.c
Log Message:
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.

This allows each call to ftp_remote() to specify the log level for any remove failure. All others file-removal failures will continue to log at ERROR level.

Actually, this assessment was wrong. fmutex_open() was memsetting the fmutex_t to zero.
