Patch 8.0.0753
Problem: A job running in a terminal does not get notified of changes in
the terminal size.
Solution: Use ioctl() and SIGWINCH to report the terminal size.
Files: src/terminal.c, src/os_unix.c, src/proto/os_unix.pro

* There are three parts:
* 1. Generic code for all systems.
* 2. The MS-Windows implementation.
! * Uses a hidden console for the terminal emulator.
* 3. The Unix-like implementation.
! * Uses libvterm for the terminal emulator directly.
*
* For each terminal one VTerm is constructed. This uses libvterm. A copy of
* that library is in the libvterm directory.

* while, if the terminal window is visible, the screen contents is drawn.
*
* TODO:
- * - When 'termsize' is set and dragging the separator the terminal gets
messed
- * up.
* - set buffer options to be scratch, hidden, nomodifiable, etc.
* - set buffer name to command, add (1) to avoid duplicates.
* - Add a scrollback buffer (contains lines to scroll off the top).
