OS X still uses clang-14, which lacks sufficient std::ranges support for
recent Rebirth changes.
- Rewrite uses of std::ranges::SYMBOL to ranges::SYMBOL
- Add a stub header that, on gcc, provides for each SYMBOL a statement
`using std::ranges::SYMBOL;`, to delegate back to the standard library
implementation.
- On clang, define a minimal implementation of the required symbols,
without constraint enforcement. Compile-testing with gcc will catch
constraint violations.
Once OS X clang ships a standard library with the required features,
this stub header will be removed and the uses changed back to their full
names.
VR requires glDrawBuffer, which Mesa OpenGL ES does not offer. Default
VR to disabled for OpenGL ES users. Users who want to try it anyway can
still set use_stereo_render=1 in the SCons environment.
The contents of the output buffer are undefined if PHYSFSX_getRealPath
fails, so mark the function as [[nodiscard]] and modify all callers to
check that the function succeeded.
Add RAII wrappers for unmounting PHYSFS paths. Use them in places that
previously handled unmounting explicitly. Also, use it for descent.hog
/ descent2.hog, which previously were left mounted indefinitely.
Some callers will need access to the computed path. Change the callers
to pass in a buffer for this path, and have PHYSFSX_addRelToSearchPath
fill that buffer directly.
OGL layer used for rendering surfaces, so using left/right viewports absent stereo quad buffers.
Using legacy Descent +/- eye offset method for left/right stereo perspective rendering passes.
PHYSFSX_isNewPath retrieves from PhysFS a list of all paths, then
searches them, and frees them at the end. PhysFS can search its own
list without needing the allocations, so delegate the work to it.
A declaration is useful if it declares an external function. A static
inline declaration, if not followed by the definition later in the same
translation unit, will not be useful. Remove such declarations, and
rely on using the definition as a declaration for those files that
actually call partial_range() or similar functions.
This fixes PCX loading in the non-editor build. PCX loading broke in
3114874713 because it switched from PHYSFSX_openReadBuffered to a call
which did not handle the presence of the marker byte in the filename.
The from_hog_only flag has not been properly supported since the
introduction of PHYSFSX_openReadBuffered in
8b323e7214. Editor builds ignored it on
purpose, and non-editor builds pretended to respect it, only to then
ignore it down inside PHYSFSX_openReadBuffered. For consistency with
code paths that do not use PHYSFSX_openReadBuffered, disable the bypass
in PHYSFSX_openReadBuffered and remove the code in show_title_screen
that applied the flag.

Processing sharepath in SConf is incorrect, because targets can share a
build directory (and therefore an SConf run), but not share a sharepath.
Move sharepath handling out of SConf. Move DXX_USE_SHAREPATH handling
from CGameArg to GameArg, since one game can be built with a sharepath
while the other is built without.
PHYSFS_init is not guaranteed to succeed. Using PHYSFS functions after
PHYSFS_init fails is likely to fail badly. On Windows, failure may take
the form of a crash in ntdll. Avoid this by exiting gracefully.

This commit enables Rebirth to build with SDL2, but the result is not
perfect.
- SDL2 removed some sticky key support. Rebirth may behave differently
now in this area.
- SDL2 removed some key-repeat related support. Rebirth may behave
differently now in this area.
- SDL2 gained the ability to make a window fullscreen by sizing it to
the desktop instead of by changing the desktop resolution. Rebirth
uses this, and it mostly works.
- Resizing while in the automap does not notify the automap code, so
the view is wrong until the player switches out of automap mode and
back in.
- SDL2 changed how to enumerate available resolutions. Since
fitting the window to the desktop is generally more useful than
fitting the desktop to the window, I chose to drop support for
enumerating resolutions instead of porting to the new API. Users can
now enter an arbitrary window dimension and Rebirth will make an
attempt to use it.
- It might be useful to cap the window dimension at the desktop
dimension, but that is not done yet.
- Entering fullscreen mode through the Controls->Graphics submenu
failed to notify the relevant subsystems, causing the rendered
content not to rescale. For now, compile out the option to toggle
full screen through that menu. Toggling through Alt+Enter works
properly.
Despite these quirks, this is a substantial improvement over the prior
commit, where SDL2 cannot be used at all. The remaining issues can be
resolved in future work.

If user_settings.sharepath is configured to be blank in SConstruct, omit
the C preprocessor macro SHAREPATH instead of defining it to expand to
an empty string. Adjust the C++ code that uses the macro SHAREPATH to
handle its absence:
- Clearer output in help text
- Skip adding blank SHAREPATH to the PhysFS search path.
As a nice side effect, this enables SHAREPATH on Windows, which could be
helpful for builds shipped with an installer that places game files in a
well-known location (such as "C:\Games\Descent"). Previously,
!defined(__unix__) systems did not add SHAREPATH to the PhysFS search
path, even when one was defined.
