See title. There were some cascade effects, but the changes are mostly contained to the model code. The calls to `gr_render_model` and `g3_render_primitives` use `const_cast` because constifying that API would require a whole other PR.

The original OpenGL Core changes only used a single vertex array object
for specifying the data layout of our vertex data. This uses the OpenGL
extension GL_ARB_vertex_attrib_binding to extend that so that each
vertex_layout uses a separate vertex array object which should improve
performance by reducing the CPU overhead while switching the vertex
layout. Since we need to use offsets into the vertex buffers at some
points this can not be done with the core functions since those do not
support specifying an offset when binding a vertex buffer.
GL_ARB_vertex_attrib_binding does support that and also features an
improved API for specifying the vertex layout. If that extension is not
available then the rendering engine will fall back to the current code.
In CPU intensive scenes I observed a frametime improvement of 1-2 ms.
All transformations are now handled by shaders so there is nothing
special going on in the graphics API specific code anymore. Since model
uniform buffers require access to these matrices I moved the matrix
handling out of the graphics API code.
This converts all usages of bmpman textures to OpenGL texture arrays.
That means that all frames of an animation are stored in a single OpenGL
texture object and can be accessed at the same time in a single draw
call. This should significantly reduce the overhead of drawing lots of
particles since all particles of a single animation can be drawn with a
single draw call.
This fixes#1169.
Replaces calls to double-precision floating point trig functions with
calls to single-precision floating point trig functions as follows:
cos() -> cosf()
sin() -> sinf()
tan() -> tanf()
acos() -> acosf()
asin() -> asinf()
atan() -> atanf()
This allows the compiler to avoid generating unnecessary instructions
that convert a float to a double and then a double back to a float.
