GNU Screen v.4.9.1

I'm announcing availability of GNU Screen v.4.9.1

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells.

This release:
* Support stop/parity bits on serial port
* Add needed system headers in checks and return values for implicit
function declarations
* Fixes:
   - Avoid zombies after shell exit
   - Missed signal sending permission check on failed query messages
(CVE-2023-24626)
   - manpage fixes
   - source code fixes during cleanup
   - UTF-8 encoding can emit invalid UTF-8 sequences for out of range
unicode values
