it could delay the acceptance of incoming Telnet/RLogin connections.

user's "time left online" anchor point (normally the same as logon_time, but
can be adjusted to add/subtract time available).

it easier to determine if a file directory is one of these special kinds of
directories.

Built-in daily event (resets statistics, deletes logon.lst file, purges old
mail, users) now runs even if no one logs on.

permissions on *nix possibly making untouchable later.

outbuf_write mutex is destroyed.

This *should* fix the crashes as the following is probably happening:
1) output_thread_terminated is signaled
2) session thread exists taking the session struct with it
3) session->outbuf_write mutex is then destroyed

wherever it's getting sucked from.

instead of a bit-mask representing all the log levels to actually "see", use a
single numeric (or nmemonic) level value (ERROR, WARNING, NOTICE, etc.)
and less severe log levels (levels with a higher numeric value) will be filtered
(e.g. not "seen" or logged). It's the basic syslog() concept.

(Where it is created)
Fixes double-destroy and lock-after-destroy error on Win32.

outbuf_write_initialized before locking/unlocking/destroying outbuf mutex.

if the filename to be edited is the same as the editor's temp file name.

Don't forget... listSemTryWait return values are reversed from sem_trywait()

Micros~1 shortened paths in the drop files. Another fix for installations to
e.g. "C:\Synchronet"

to be moved into a hashlib (todo).

some XSDK doors to possibly work when run from C:\Synchronet\...

Also fix incorrect type lassed to iniFreeStringList.

(Should this be a separate type then?  ini_list_t or something?)

Fix sizeof(char*) leak when reading a webctrl.ini file.

None of these added FREE_AND_NULL() calls should actually do anything.
