Revert "i965: Disable guardband clipping in the smaller-than-viewport case."

This reverts commit 0bac2551e40410e2251daf4fd9faf69310ab34ce.

Now that we position the guardband correctly (applying translations
in addition to scaling) and made it as large (or larger) than the
render target, this shouldn't be necessary.

Now we leave guardband clipping enabled 100% of the time, like the
Windows driver does.

Fixes GL45-CTS.gtf21.GL2FixedTests.clip.clip.  It tries to draw a
16384x64 rectangle, and it appears that some kind of numerical
imprecisions in the clipper result in some edge pixels going missing.

i965: Always scissor on Gen6-7.5 instead of disabling guardband.

Previously we disabled the guardband when the viewport was smaller than
the framebuffer on Gen6-7.5, to prevent portions of primitives from
being draw outside of the viewport.  On Gen8+, we relied on the viewport
extents test to effectively scissor this away for us.

We can simply always enable scissoring instead.  We already include the
viewport in the scissor rectangle, so this will effectively do the
viewport extents test for us.  (The only difference is that the scissor
rectangle doesn't support sub-pixel values.  I think that's okay.)

Given that the viewport extents test is essentially a second scissor,
and is enabled for basically all 3D drawing on Gen8+, it stands to
reason that scissoring is cheap.  Enabling the guardband reduces the
cost of clipping, which is expensive.

The Windows driver appears to never disable guardband clipping, and
appears to use scissoring in this case.  I don't know if they leave
it on universally though.

This fixes misrendering in Blender, where the "floor plane" grid lines
started rendering at wrong angles after I disabled XY clipping of line
primitives.  Enabling the guardband seems to solve the issue.

i965: Use a better guardband calculation.

(Patch co-authored by Jason and Ken.)

We scaled the guardband based on the viewport size, but failed to
take into account the translation portion of the viewport transform.

This meant the guardband was always centered around the origin.
We want it to be centered around the screen-space drawing area,
which is the intersection of the viewport and the render target.

At best, getting this wrong would reduce the guardband's effectiveness
in some cases.  At worst, it might break things - objects outside of the
guardband are trivially rejected, so getting the guardband in the wrong
place and leaving guardband clipping enabled could cause problems.

v2: drop clamping of positive maximums.

main/framebuffer: refactor _mesa_get_color_read_format/type

Current implementation returns the value for the currently bound read

given framebuffer. GetFramebufferParameteriv would be also interested
on that method

It was refactored by allowing to pass a given framebuffer. If NULL is
passed, it used the currently bound framebuffer.

It also adds a call to _mesa_update_state. When used only by
GetIntegerv, this one was called as part of the extra checks defined
at get_hash. But now that the method is used by more methods, and the
