Allows MSAA colorbuffers, which have a CMASK automatically and don't
need any further special handling, to be fast cleared. Instead
of clearing the buffer, set the clear color and the CMASK to the
cleared state.
Fast clear is used only when all bound colorbuffers fulfill certain
conditions: a CMASK is required, we have to be able to create a clear
color value for the format and the texture mustn't contain multiple
images. Technically, it should be possible to support array textures
and cubemaps if all images are attached to the framebuffer,
but this does not appear to be common.
v2: fix fast clear check
v3: Marek: - disable fast clear with 128-bit formats, which are unsupported
- set tex->dirty_level_mask in r600_clear, so that the driver knows
the resource must be decompressed/expanded
- return early from r600_clear if there's nothing else to do

b04a295a4a removed seemingly unnecessary
code in get_query. Turns out this code could in fact be reached - while
timestamps are always binned, if there are no bins (which happens if fb
size is 0) then the rasterization query code filling this in is still
never executed.
So fix this up by filling in some timestamp, but do it at EndQuery time
not GetQuery time which should be more appropriate.
Makes piglit arb_timer_query-timestamp-get happy again.

While i915 does have hardware contexts in hardware, we don't expect there
to ever be SW support for it (given that support hasn't even made it back
to gen5 or gen4).

Every driver left in Mesa that enables one also enables the other.
There's no reason to let it be optional.

In Mesa, this extension is implemented purely in software. Drivers may
*optionally* provide optimized paths. If a driver enables,
GL_ARB_texture_multisample, it gets GL_ARB_texture_storage_multisample
for free.
NOTE: This has the side effect of enabling the extension in Gallium
drivers that enable GL_ARB_texture_multisample.
v2 (Ken): Still prevent multisample texture targets in TexParameter for
implementations that don't support multisampling.

This extension just provides some of the most basic software framework
for GLSL. Without GL_ARB_vertex_shader or GL_ARB_fragment_shader,
applications still cannot use GLSL. There's no value in
conditionalizing support for this extension.
