Start hacking on fit-checking code
Add NI_walk_children() to call a callback for each child
Move functions that have no generated bits into newifv_nongen.c
Call the object set/get function for globals to allow range checking

Basically, the intent is to do a modern (for C) interface which
allows reproducing the look and feel of uifc but without hurting
as much.

The intent is to support a tree of objects, each of which have
an attribute get/set function as their main interface.

Various callbacks will be supported for various object types, and
positioning will be relative to the "child area" of the parent.

The SyncTERM main screen is expected to look something like:
root
+--frame (dialing directory)
|  +--list
+--frame (settings)
|  +--list
+--textinput (comment)

Internally, the code is wildly type-unsafe, but there's an
auto-generated API (which is the only thing exported) that is
type-safe.

This also introduces the CuTest C test suite as an experiment.

... and rearranged them to match SCFG->System->New User Values->QWK Message
Packet Settings more closely.

uedit (the program) should be updated too.

Silly me, this is C++, do the C++ thing

No functional change.

Seems a useful function to have on hand. Especially now that it's "fixed"
(will convert "1234" to "1,234").

I noticed while testing the previous commit that 4 digit values weren't
thousands-separated, while larger values were. I'm not sure why this
non-zero index check was in this loop, but appears to be a bug.

- bbs.expand_atcodes() now supports formatting (did not before this)
- text.dat/ini strings now support @-code formatting (did not before this)
  (this fixes issue #697)
- bbs.atcode() now supports more complete formatting (only supported -R/-L
  previously)

The -W (wide) formatting code is not supported in these cases since that code
currently sends UNICODE sequences directly to UTF-8 terminals, when used.

sbbs_t::gettimeleft() was storing a pointer to a stack (temporary/local)
variable containing a copy of the next exclusive event cfg (including its
internal code). This variable, including the internal code, is invalid when
it goes out of scope. This change makes the sbbs_t::event_code point to the
sbbs_t::cfg.event[]->code (on the heap) instead.

The only use of this event_code (outside of the event_thread), appears to be
in the JS bbs.event_code property string. So this fixes issue #705. No other
observed side effect from this bug.

Constified getnexteventtime() while here. No functional impact.

Fixes issue #704 - not just for JS bbs.edit_msg(), but for all uses of the underlying sbbs_t::editmsg() function.

Replaced one specific comparison of subnum == INVALID_SUB with call to is_valid_subnum() just to be consistent. No functional change there.

Conditional jump or move depends on uninitialised value(s)

Introduced in commit 48e7520e (when colors was converted from a byte array
to a uint array), we weren't memsetting the right number of bytes.

Since color is not an array of ints (not bytes), memset (of non-zero values)
isn't really the right initialization approach anyway. Now using a for-loop.

But continue initializing/running for other non-TLS protocol support.

<Deuce> Feel free to not lock the mutex and never free/NULLify that string.
<Deuce> Should be nicer for people with separate logs, and a few bytes never hurt anyone.

handler it.

This is a new error that just started cropping up. I suspect it's related to recent SSH changes. This might help a little with context, when it happens again.

Totally not sketchy, trust me.

Interestingly, when they fail, Synchronet appears to crash.
This is fine.

These should've been static to begin with, like the other servers. Explains why FTP error message are with "term" as the server.

(such as ec22519), unconditionally fallback to password auth instead
of the previous behaviour of diconnecting.

Much of the "password then pubkey" mentality is showing in these
bits of Cryptlib.

For Nightfox and his newsgroup reader thing: The strings that end up in the editor drop file (e.g. MSGINF) can now be passed as optional arguments to consol.editfile() and the underlying C++ API.

Allow maxlines (default:10000) to be overridden with an optional consol.editfile() argument too.

On Win32, size is explcitly "ignored" when target is NULL, so we
should set it to the size of the allocation.

Previously, once a pubkey was attempted, you could not use a password.

When we're closing the socket, always delete channels and don't wait
for the remote to confirm.

Fixes assertion failure on hangup from SSH.
