Issue introduced in previous commit to this file. The name arg(s) comes before the address arg(s).

If the destination point node is not a linked node (does not exist in sbbsecho.ini), but the boss node is linked, automatically route to the boss node. The log entries look like this when this happens:
"Routing packet (%s) to boss-node %s"
"Routing NetMail (%s) to boss-node %s"

For poindexter FORTRAN (REALITY) - test results appreciated.

Incremented SBBSecho version to 3.13.

Previously, any DNS blacklist-exempt email addresses (in ctrl/dnsbl_exempt.cfg) had to be used in the mail-envelope (the "MAIL FROM:" address) - that doesn't work for all senders that use re-mailers or whatever where you end-up with some *bounce* address as the envelope-sender.

So now, clear the DNSBL results when the From header field is parsed and the sender was in fact an exempt sender. Note: the Subject line will still contain the SPAM tag if the subject was parsed first (came earlier in the message header). May need to address this limitation in the future if it turns out to be a problem (!).

Lowercase the [smtp|smtps]spy.txt log file.

protected_*_adjust() only adjusts now.

Deal with the resulting warnings (using (void)).
Deal with the incorrect integer to protected_int* assignment in services.c
(just don't support server.clients property reading in service scripts).

Also, the strcpy()->SAFECOPY() change in ftpsrvr.c was wrong, caught
by GCC warning - oops.

Also, fix things that incorrectly reach into the protected_*_t to
incorrectly access values.

This reverts commit e1e034cc.

Didn't work for .cpp files:
stdatomic.h:40:9: error: ‘_Atomic’ does not name a type
typedef _Atomic _Bool atomic_bool

Synchronet's whims. Check for falsiness instead of NET_NONE.

Just display to/from_net_addr without prefixing with to + @. Not
sure why I was doing this, but if there was a reason, I'll need
to make an per-net-type address formatting thing.

Mail wasn't being marked as read unless the user hit 'Q' from the msg view mode.
Reported by Keyop via IRC.

'darkmode_off' will still work if set, but is deprecated.
Added 'darkmode_on' setting, which defaults to false;
if set, darkmode is turned on until the user turns it off.

If your browser is from another geological epoch, I have no sympathy for you.

Previously, 403 was only returned if they existed, and 404 if they
didn't.

No need to get time() here since it's never checked.

Resolves CID 174292

Have free_paragraphs() explicitly allow paragraphs to be NULL and
have everything use the fail_return which now free()s ret.

Previously, more than 999 arguments would overrun a buffer and break
things.

Fixes CID 33313

Are you tired of getting TLS-related error log messages that you can't do anything about? e.g.
web  0139 TLS ERROR 'Received TLS alert message: Unexpected message' (-15) setting session active

The new sbbs.ini [web] TLSErrorLevel option (defaults to 0 / "Emergency") allows the sysop to set a cap (maximum severity) on TLS-related log messages in the web server (e.g. TLSErrorLevel=Warning).
