Namely: no, yes, and yes and ask at startup.
The install_check option is thus replaced by the can_install option. -Dinstall_check=true maps to -Dcan_install=yes_check, while -Dinstall_check=false maps to -Dcan_install=yes. -Dcan_install=no is new and is recommended for downstream packaging, where -Dinstall_check=false was historically used.
Also improve error messages about bad configuration here and there and scatter configuration code in subdirectories, where they can be closer to their areas of effect.
Also make ENFORCE_HTTPS optional, but default to enabled, so unencrypted HTTP is disabled by default, and require it to be enabled for release binaries.
Also Disallow linking against non-C++ system Lua, unless configuring with -Dworkaround_noncpp_lua=true, add -Dworkaround_elusive_bzip2 and friends, and get rid of the -image_base hack for macos.
Also Factor out app constants that mods might change into Meson options and clean up format::URLEncode in the process, convert app and document icon data in arrays to actual images, actualize AppStream data for possible future packaging, add alternative command line format for opening filesystem saves and ptsave URLs, fix a memory leak in Platform::GetCwd, and add format::URLDecode.
Also restructure meson.build and the ghactions workflow a bit, and enable -ffunction-sections and -fdata-sections.
Note that starcatcher uploads have not been tested and most likely don't work.
Certain file managers need this figure out that the executable is actually executable. The problem is further complicated by meson being uncooperative and not implementing its own -Db_pie=false correctly.
I forgot to update meson_options.txt when committing 360297c. At that
point, FUTURE_SAVE_VERSION in Config.h was 96. Without that, the game
can't load saves with GOL because they save as v96 elements.
Please update your existing build sites with
meson configure -Dfuture_major=96
as this change won't affect them unless you do.
