mesa: increase number of texture units to MAX_COMBINED_TEXTURE_IMAGE_UNITS
We were misinterpretting GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS previously. It's the number of texture units for which we need to keep state; not just the total number of texture units addressable by the vertex shader plus fragment shader. Since sw Mesa independently supports 16 texture units in vertex shaders and 16 texture units in fragment shaders, the max combined units is 32. Note that the docs for glActiveTexture() indicate the max legal unit is MAX(GL_MAX_COMBINED_TEXTURE_IMAGE_UNITS, MAX_TEXTURE_COORDS) - 1. A new piglit test (texunits.c) tests the various texture unit limits. I'm pretty sure I've got this all right now, but additional reviews are welcome...
