(dirs and files).  Include the unique fact in aliases as well.  Clients can
now tell that aliases are the same entry.

For MLST <dir>, always return the full path of the dir instead of the
specified or relative path.

Likely some other minor fixes as well.

like symlinks... note that they aren't shown as symlinks in the directory
output, so it may be a bit of a surprise when relative paths are relative
to the target rather than the alias.

to handle this somehow (but currently doesn't).
Also, remove some debug output.

Add the '..' parent directory to libs and dirs
Fly the TVFS flag now that relative dirs are working

LIST should likely check the return value now...

Add support for OPTS MLST command.
Fix MLST FEAT response.

in the other stuff too.  The local mounts may not be at 100% either, but
the appear to work.

I wasn't expecting to do this, since SFTP is often viewed as "better", but
SFTP doesn't have a specification, the implementations don't follow the
specification drafts that are out there, and the whole sharing a port between
file transfer and terminal server thing is irritating.

This has only been tested with lftp, but it seems to work.

it's non-zero.

HANDLE_PENDING() contains a return, so it's theoretically possible that the
memory allocated by the previous JSVALUE/STRING_TO_... allocation could
be leaked. So now we pass an optional pointer to HANDLE_PENDING() which will
call free() on it if it's not NULL, and then sets it to NULL for good measure.

Lower likelihood that ftp_remove() will log a false error.

accepted (e.g. "EPSV 2"). For now at least, accept any arguments after EPSV
(and treat them all the same).

(currently only via FTP) - simiilar to the global FTP option: DIR_FILES.
I intend to extend this option to the terminal server as well.

globally (using a new macro in sbbbsdefs.h: STR_UNKNOWN_USER). "<unknown>"
in some contexts was too vague (e.g. the 'c' command output from the sbbs
console).

temp-ban (was logging the total number of login attempts, including dupes).

so use shorter thread names.

How did startup->sem_chk_freq get set (back) to 0 in the first place?
The reason: the startup struct sanitization only occured when the various
server threads were first started. When recycled, the server would call back to
the original caller (e.g. sbbscon) which may (and did) re-read the sbbs.ini
file, which could have SemCheckFrequency set to 0 (or missing) and the
sanitization did not happen again (so a 0 value was used in select() calls,
resuilting in high CPU utilization for several threads).

So now, all startup struct sanitization occurs inside the init/recycle loop
and sem_chk_freq should never revert to 0 again. This was the main bug.

value is missing or set to 0 in the sbbs.ini file, the sanity checking this
value (setting it to 2 seconds) will not occur after a server recycle and the
sbbs.ini is re-parsed. So if for any reason, the sem_chk_freq value becomes
0, these server threads won't hog the CPU because they all YIELD at the
top of thier main loops.

Also, changed all the thread names (e.g. adding "sbbs/" prefix), so they're
more sensible in the Linux 'top' output.

Also, started adding 'vi' modelines to auto-set tabstops when using vi/vim.

file (in .can file format) which lists IP addresses or hostnames which will
be exempt from temporary bans or permanent filters.

- Never ban the server's own address
- Log the login attempt and last name attempted
- Use a compressed version of the HH:MM:SS "time remaining" portion of the log

By default, after 20 consecutive (unique) failed login attempts, *or*
a failed login attempt wtih a name from the name.can filter file.
The default temporary ban duration is 10 minutes.
The temporary ban thershold is configurable via LoginAttemptTempBanThreshold
in sbbs.ini and the ban duration is configurable via LoginAttemptTempBanDuration
(in seconds).

the constructor things.  This allows TLS-enabled services to work correctly,
and removes an ugly hack from the web server.

There's still an odd issue with the NNTP service when using TLS though.

to errorlog() so the data/error.log is less ambiguous about where an error
occurred.

addresses specified in the Interface line of sbbs.ini for the server.

before re-reading them.

xpms_add_chararray_list instead.  Prevents having to free string lists
in the sbbs.ini parsing code.
