So we don't have to reimplement this logic in user_settings.js (or
equivalent) any longer.

Also, fix manpage generation for CMake.

I've forgotten one of these for every RC except the first one for
v1.2. :(

Thanks nelgin.

The amazing Haiku community has redesigned the SyncTERM icons for me!

Unfortunately, I had to remove the default "Synch" icon from ciolib
so that SyncTERM could have its own separate icon. :(

I'm not sure if the msvc builds are using the ciolib.rc file or not,
and I'm not sure how they can add an icon... I'll net DigitalMan sort
that out (sorryish).

This was sometimes causing an integer scaled mode (ie: 4×) to be
reduced to very slightly less than that (ie: 3.996255×), making the
window one pixel smaller than it was supposed to be due to integer
truncation.

This could result in being unable to increase the window size using
the Alt+Right-Arrow shortcut and could make new windows one full
size smaller than they needed to be (such as C64 windows).

While we're here, fix the SDL and X11 outputs to trust what
bitmap_drv_init_mode() does.  It was fixed when GDI mode was being
written, but the other drivers weren't updated to take advantage of
that.

Should resolve issue 156 reported by DigitalMan

Whee.

Use localizable [Q]uit key

Removed trailing whitespace

Now it doesn't leave the console all messed up.

Helpful for a JS batch file transfer menu

Returns count of files removed now (not bool).

This allows GetConsoleScreenBufferInfoEx() to work for palette
changes, allowing Console to not suck.  However, we now prefer
ANSI mode over Win32 Console, so make that so it can actually
fail on Windows of stdout is a TTY and we can't set the
ENABLE_VIRTUAL_TERMINAL_PROCESSING flag.

With this, ANSI mode is used in Windows Terminal, and Win32 Console
is used in Legacy Console, and all should be good with the world.

CSI s and CSI u are ANSI.SYS extensions, and aren't needed here.
We're clearing the screen and moveing the cursor anyway.

Not only was it broken when window() is set, it's also broken when
the width is not the full screen width.

We've now disabled pretty much all the optimizations... but it works.

Specifically, make Win32 Terminal output not suck.
If stdout is a tty, set the palette appropriately, avoid using \n
since Windows can't seem to be stopped from expanding it to \r\n
nd brob the Console modes a bit harder.

The window and the screen buffer are two different things... the
screen buffer must always be the same size as or larger than the
window.  Further, there are times where it's not possible to resize
the windown programatically (new terminal for example).

There still appears to be a stupid bug in what I assume is the
Windows Terminal LCF flag implementation which causes writes to
the beginning of a line that occur after a write to the end of the
previous line to be in the wrong position.  If it's not the LCF flag
(which isn't turned on), it's in their wrapping thing which is extra
irritating since I explocitly turn that off.

Almost there, the main issue remaining is when running from a
command-line, it sometimes "unwraps" lines.

Likely still not right though.

Because it screws up the display when you resize the window.

This was broken when SFTP support was added and wasn't noticed.
Big thanks to Scott Labrecque of ems-bbs.com for noticing!

This doesn't fix the terrible crap Windows does to the contents of
the console yet though (sigh).

These 2 properties, specifically, could be made writable since
1. smb_t.curmsg is a special element owned by the application, not smblib
2. a special sbbs_t.current_msg_number property could be created/used to
   underlie the bbs.msg_number when there's no open message base (by sbbs).

This might be all that's needed to resolve issue #793

The other bbs.msg_* and bbs.smb_* properties are not so easily made writable,
so hopefully that's not desired.

So we need to define the Windows API ourselves. :(

SetConsoleScreenBufferInfoEx() can no longer set colors in the
console palette.  Switch to virtual terminal parsing stuff and send
some ANSI to adjust the palette instead.

And try to make it clear that multiple bases can be passed on the command-line.

This was disabled due to mingw32 limitations, and we use mingw64 now

Fix issue #801

Now that the conio layer is handling translation of character sets,
the key handler in term.c should only handle terminal related
translations (such as backspace to delete).

This fixes bug 159, but there's still some inconsistency across
the various backends on how they handle C0 control characters and
input characters outside of US-ASCII.
