Only supported on FreeBSD, Linux, Solaris, OS/2, GNU, Cygwin, and Darwin
Should allow OpenBSD to build JS engine.

Not yet tested, so more patches may be incoming.

There are too many options now to fit in an 80x25 screen, so group
all the log options into a separate sub-menu.

While we're here, notice that we're writing paths up to MAX_PATH
into an 80-character buffer and fix that.

Do not get/set these values on other OSs.  Fixes a segfault caused
by default_dosemuconf_path being undefined on FreeBSD, but would
also happen on any other *nix platform (ie: OpenBSD, etc).

Some broken protocol drivers (like sz) don't send a YModem terminate
at the end of a batch (or maybe just after a single file?) so SyncTERM
ends up trying to fall back from G to CRC-16 to 8-bit before ending.

This detects when the last known file was received, and if the YModem
header that follows is not correct, aborts the transfer.

Something weird is happening to the cryptlib session when SZ sends
a lot of data... no real clues left.

This issue may actually be a rekey issue, to clear this, we need
to call cryptPopData(), but we can pop zero bytes.

In this case, re-try the flush.

During YModem-G transfers, the previous 5-second timeout was
exceeded.

Just copied out of the documentation.

It's not clear if this is working properly or not since the only
BBS I know of that supports telnets (fido.beholderbbs.org) doesn't
seem to do any telnet "stuff".

Should fix SF #45 since it appears the input thread started then
exited before SyncTERM realized the connection was successful.

In preperation for telnets support, make conn support TX/RX parsers.
Make telnet use those new hooks, and remove unused and ambiguous bits
of the conn API (conn_recv(), conn_peek()).

All the major bugs I'm aware of are fixed (though RIP is still
incomplete)

Make an exception for all keypad stuff.

Cursor update issue, cursor was only redrawn on a blink status change.
This will redraw the cursor any time the cursor moves now.

Should fix file transfer issues.
(SF bug #38)

for Al (TRMB) and his Russian users, requested via DOVE-Net.

Do an FTN "ASCII 1" -> "US-ASCII" translation of the CHRS->charset too.

Clang 11 throws an error if you do.

Presumably these were part of macros once and never cleaned up?

Just rename ESCDELAY member to escdelay.

remove() is expected to fail in this scenario sometimes depending
on how writemsg() is used - in the error case, the user was trying
to edit his .plan file with the ;plan command:
term Node 10 <Deuce> !ERROR 11 (Resource temporarily unavailable) in writemsg.cpp line 1232 (editfile) removing "/sbbs/node10/temp/INPUT.MSG" access=0

Thanks for the bug report!

Apparently, the ncurses in openSUSE Leap-15.2 has the following:
Since we have a struct member named ESCDELAY, we can't actually set
it at all when this macro is defined.

The three possibilities to deal with this are:
1) Rename the ESCDELAY member.
   Likely the best option long-term, but I don't want to find everything
   and update it at this time.
2) Avoid using the ESCDELAY member #ifdef ESCDELAY
   Which makes it not work in the exact set of circumstances it makes
   sense in.
3) #include curs_fix.h from ciolib.h
   This actually renames the ESCDELAY member to _nc_ESCDELAY, but you
   won't be able to actually notice this.

Before the Unicode support was added, displaying a NUL would clear
the cell, but now it is translated.  For ATASCII, this results in
a heart character being displayed instead of an empty cell when
inserting or deleting characters.

Fixes bug #28 on Sourceforge.

The low byte is no longer zero.

or any lines that were only terminated with carriage-return (\r)
since these are treated rather-oddly by the FTN software as a
line-ending and line-feeds are to be ignored. So transfer \r to \n
on output and ignore the \n's in the body text.

Just delete the old private key and create a new one for the new
host.

Remove obsolete comments, and remove an extraneous savetime call.

Currently, this is hard-coding the name of the key, which should
be read from the letsyncrypt.ini file in case someone is using an
ACME v2 service that is not provided by letsyncrypt.org.
