Updated: vttest 20241208 - test VT-type and X terminals and emulators

[Cygwin vttest Maintainer]

Tests the functionality of a VT100 terminal (or emulator thereof).
Tests both display (escape sequence handling) and keyboard.
The program is menu-driven and contains full operating instructions.
To run a given menu-item, you enter its number. You can run all
menu-items (for a given level) by entering an asterisk, i.e, '*'.

It has been enhanced to support and test many xterm control and status
escape sequences, and it is mainly used nowadays for testing emulator
compatibility.
