gallium: remove PIPE_TEX_FILTER_ANISO
This patch removes PIPE_TEX_FILTER_ANISO. Anisotropic filtering is enabled if and only if max_anisotropy > 1.0. Values between 0.0 and 1.0, inclusive, of max_anisotropy are to be considered equivalent, and meaning to turn off anisotropic filtering. This approach has the small drawback of eliminating the possibility of enabling anisotropic filter on either minification or magnification separately, which Radeon hardware seems to support, is currently support by Gallium but not exposed to OpenGL. If this is actually useful it could be handled by splitting max_anisotropy in two values and adding an appropriate OpenGL extension. NOTE: some fiddling & reformatting by keithw to get this patch to apply. Hopefully nothing broken in the process.
