Replace MESA_FORMAT_DEPTH_COMPONENT_FLOAT32 with 32-bit integer format.
This allows render to depth texture (we don't support floating pt. Z buffers). Rename MESA_FORMAT_DEPTH_COMPONENT16/32 as MESA_FORMAT_Z16/32. Software fallback for glCopyTexImage now uses integer temporary image instead of float, eliminates a lot of float/int conversions.
