    r300: Cleanup LodBias support
    
    . There is both a per-texture unit and a per-texture object (at least for
    OpenGL 1.4); this should now be supported properly.
    . The LOD bias calculation in r300_state has been simplified and corrected
      (need to multiply by 32 instead of 31, and ensure clamping)
    . do not clamp LOD bias in TexEnv, as that behaviour conflicts with what
      the spec says
    . set Const.MaxTextureLodBias properly
    . remove the no_neg_lod_bias property; if somebody can explain what
      it's good for, we can add it back in, but according to Google, nobody
      seems to use it
    . removed some dead code and unused variables
