Conn O'Griofa 457dc8b5a9 Use signal handler to invoke call_terms() before exit when possible 
It's not advisable to rely on atexit() to invoke SDL_Quit(), as it
causes a segmentation fault on exit for the SDL2 KMSDRM driver due to
a conflict with the Mesa drivers* which upstream Mesa may not elect to fix.

The issue can be resolved by replacing the atexit() call with a signal
handler that will interrupt the D_DoomMain() and D_DoomLoop()
functions, then invoke call_terms() within the main thread before exiting.

We can leave the atexit() hook intact to handle edge cases such as abnormal
process exit, or exit methods which do not produce signals such as Alt+F4 or
window close via GUI (neither of which are possible in a KMS context, so
should not affect KMSDRM sessions).

Fixes a segmentation fault/uninterruptible application hang on exit
for all KMS targets, including Raspberry Pi 4B, 3B and Intel i965.
