c0c45d325d OpenGL2: Readd r_deluxeSpecular.

5909b9a1cf Isolate the Altivec code so non-Altivec PPC targets can use the same binary.
Moved all the code using Altivec intrinsics to separate files. This 
means we can optionally use GCC's -maltivec on just these files, which
are chosen at runtime if the CPU supports Altivec, and compile the rest
without it, making a single binary that has Altivec optimizations but
can still work on G3.

Unlike SSE and similar extensions on x86, there does not seem to be
a way to enable conditional, targeted use of Altivec based on runtime
detection (which is what ioquake3 wants to do) without also giving the
compiler permission to use Altivec in code generation; so to not crash
on CPUs that do not implement Altivec, we'll have to turn it off
altogether, except in translation units that are only entered when
runtime Altivec detection is successful.

This has been tested on Linux PPC (on an Altivec-enabled CPU),
but we may need further work after testing trickles out to other
PowerPC devices and ancient Mac OS X builds.

I did a little work on this patch, but the majority of the effort belongs 
to Simon McVittie (thanks!).

42d2fb908c OpenGL2: Fix parsing specularScale in shaders
Fix specularScale <metallic> <smoothness> with r_pbr 1 which has been
broken since r_pbr was implemented in 2016.

Fix specularScale <r> <g> <b> <gloss> setting b to gloss and leaving
gloss as 0 since it was implemented in 2014.

3d6aa05694 OpenGL2: Fix dark lightmap on shader in mpteam6
Team Arena's mpteam6 map has a shader textures/base_wall2/space_concrete
that contains an opaque stage, two non-lightmap blendfunc filter stages,
a blendfunc add stage, and a lightmap stage. The lightmap was attached
to all four of the non-lightmap stages causing the filter stages to
darken the lightmap multiple times.

Change setting up the lightall GLSL shader to only use lightmap if it's
the first stage or not a blendfunc filter stage. Now only the opaque
and blendfunc add stages of the mpteam6 shader use the lightmap.

Reported by Alexander Nadeau (wareya).

ac4802af8d OpenGL2: Fix brightness when r_autoExposure is disabled
The game world is too dark when r_autoExposure is disabled. It can be
fixed by setting (cheat) r_cameraExposure to 1 but then the game is
too bright when r_autoExposure is enabled. So default r_cameraExposure
to 1 and make auto exposure subtract 1 from r_cameraExposure value.

- Add GL_VERSION_ATLEAST(major, minor) macro.
- Get address of glGetStringi if using OpenGL 3.
- Fix glConfig.extensions_string when using GL3 core context in
opengl2 renderer.
- Make opengl1 renderer's gfxinfo support qglGetStringi too.

20573bce43 Don't link to libGL at compile time
Get all OpenGL functions using SDL_GL_GetProcAddress(). This makes it
easier to cross-arch compile on Linux and add support for OpenGL ES
in the future.

Users still have to supply their own libSDL2 for cross-arch compiling
on Linux. But now the user does not have to re-install libgl1-mesa-dev
package for i386 or amd64 on Debian when switching between compiling
ioquake3 for x86 and x86_64.

6f0736ce9a Fix loading renderer DLLs on Windows x86
After 'Fix floating point precision loss in renderer', Windows x86
client won't load the renderer DLLs. The problem is a 64 bit modulus.
I couldn't find any reports of this online. However, client with
built-in renderer worked with the 64 bit modulus.

Only tested with mingw-w64.

Zack Middleton
904bbc1a8f Allow more than 32 surfaces in skin files
Models don't have a surface limit; skins shouldn't either. Some player
models require more than 32 surfaces since vanilla Quake 3 did not
enforce the limit.

Skins are now limited to 256 surfaces because having no limit would
require parsing the skin file twice. The skin surfaces are dynamically
allocated so it doesn't increase memory usage when less surfaces
are used.
