This new libXfont API eliminates exposing internal X server symbols to
the font library, replacing those with a struct full of the entire API
needed to use that library.
v2: Use libXfont2 instead of libXfont_2

There is a problem with some fonts that the height necessary
to store the font is greater than the max texture size, which
causes a fallback to occur. We can avoid this by storing two
macro columns side-by-side in the texture and adjusting
the calculations to suit.
This fixes

running xfontsel on haswell here, with a max texture size
of 8kx8k, one font wants 9711 height. This fallsback to
sw in this case.
A proper solution probably involves using an array texture.

Remove the calls to GL_TEXTURE_MAX_LEVEL. Setting the filtering is
a sufficient hint to the driver about texture mipmap allocation.

This happens to avoid GL errors on hardware without
EXT_texture_integer (which implies < GLSL 130, and thus glamor_text.c
programs not compiling anyway).

With GL_TEXTURE_MIN_FILTER, we configure not to use mipmaps, but
there's no real way until GL_ARB_texture_storage to dictate whether
memory should be allocated for mipmap levels or not.
GL_TEXTURE_MAX_LEVEL is a stronger hint to the driver than the
filtering that we really don't want mipmap allocations. Stops VARM
wasting warnings from the nvidia driver.
