    st/mesa: implement blit-based TexImage and TexSubImage
    
    A temporary texture is created such that it matches the format and type
    combination and pixels are copied to it using memcpy. Then the blit is used to
    copy the temporary texture to the texture image being modified by TexImage or
    TexSubImage. The blit takes care of the format and type conversion and
    swizzling. The result is a very fast texture upload involving as little CPU
    as possible.
    
    This improves performance in apps which upload textures during rendering.
    An example is the Wine OpenGL backend for DirectDraw, which I used to test
    the game StarCraft. Profiling had shown that TexSubImage was taking 50% of
    CPU time without this patch, which was the main motivation for this work, and
    now TexSubImage only takes 14% of CPU time. I had to underclock my CPU to see
    any difference in the game and this patch does make the game a lot faster
    if the CPU is slow (or using the powersave cpufreq profile).
