We're leaving the "Awesome Modes" as 1:1, but the rest all assume
a 4:3 display that is filled by the described text.

Instead, just set bar to the end and let ulist() sort it out.  It
sucks, but it sucks less.

Microsoft wants us to use a manifest for this, but I really don't
feel like digging into however one uses manifest files when not
using the Microsoft build files.

This may solve issue where using Windows "DPI scaling" forces the
window to be scaled.

New text.dat string:

Removed text.dat string:
DeleteExtDescriptionQ

Altere reported via IRC:
!ERROR -1 (113) connecting to passthru socket

It might be helpful to know the address the passthru socket is bound to and the connection is being attempted on, so log that with the error.

This is the likely cause of Phil's reported errors when removing files:
access=-110 info=smb_removefile name not found

The only way I was able to reproduce these errors was to attempt to remove the same file multiple times in the same file listing. In other worse, use 'R', remove a file, then 'P'revious back to the first file and try to remove it again. Or to remove it a file from the batch flag prompt and then attempt to remove it again. <shrug>

This eliminates any ambiguity about what exact version was in use when each error is logged.

CID 330960, 330967, 330988

If the file doesn't already have a description, f->desc may be NULL.
Remove the redundant user name in the "removed file" log message.

This may have contributed to plt's file editing woes.

Fix issue reported by Jay Crutti.

CID 331582

Make it the default.

#pragma clang causes an error
__attribute__ not supported

This uses the 720x400 with 9x16 character cell that always made
BBSs look so terrible.

I do, so you should too!

This fixes issues where "leftovers" from the previous mode would
remain in a new screen mode.

Also, include math.h

Sheesh.
