Improve threads demo test/threads.cxx (#1263)
- Replace Fl_Browser with Fl_Terminal which uses a constant buffer size
- Don't lock the GUI for every single prime. Collect primes for at
least 0.25 seconds before calling Fl::awake(handler, buffer)
- Use (two) alternate buffers for collecting prime data.
- Use Fl::lock() *only* to protect thread data at initialization time.
Observation on Debian 12, CPU: 12-core, 12th Gen Intel Core i7-1260P:
speedup > factor 4, using multiple cores,
GUI fully functional: scrolling the display, resizing, ...
Tested natively (X11 + Wayland) and cross-compiled for Windows,
using `wine`.
