general fixes and cleanup

• latest PDCurses if needed
• work with compilers lacking random_init()
• general cleanup and maintenance

simplify code, enhance sleep robustness

v1.7.0

remove unused script [skip ci]

improve shared lib build option

v1.6.0

meta

compiler gen expr options, packaging meta

v1.5.4

v1.5.4

improve curses build, working on Windows Intel compiler

v1.5.3

v1.5.3

static link exe only mingw, cmake packaging

• improve cmake install package
• only static link libgfortran in MinGW to avoid possible Mac/Linux issues

CMake: add C-Fortran ABI check

add a tiny test project to help ensure that the C and Fortran compilers can link a joint program, at configure time.

executable package

binary downloads attached to each CI run and release. The tetran executable is under the bin/ folder.

For example, Windows users download tetran-Windows.zip. Inside under tetran-Windows/bin/tetran.exe is all you need to play. The other files are just metadata and documentation not needed.

other notes

• make program front end separate from "libgame"--a first step toward that
• make GUI tests not run in parallel with other sensitive tests as they fail

test bugfix: parallel gui

fix bug for testing that would fail on windows if gui tests run simultaneously

autobuild curses with cmake or meson if needed

also:

• use Fortran, C standard sleep that works on WIndows, Linux or Mac across compilers
• don't run GUI tests in parallel as they may fail
