i915g: fix incorrect gl_FragCoord value

On Intel Pineview M hardware, the i915 gallium driver doesn't output
the correct gl_FragCoord. It seems to always have an X coord of 0.0
and a Y coord of the window's height in pixels, e.g. 600.0f or such.

I believe this is a regression caused in part by this commit:
afa035031ff9e0c07a2297d864e46c76f7bfff58

The old behavior used the output at index zero, while the new behavior
uses actual zeroes. In the case of gl_FragCoord the output at index
zero happened to be the correct one, so the behavior appeared correct
although the code already had a bug.

Fixed by checking for I915_SEMANTIC_POS when setting up texCoords. If
the generic_mapping is I915_SEMANTIC_POS, look for the
TGSI_SEMANTIC_POSITION instead of a TGSI_SEMANTIC_GENERIC output.

st/nine: Fix check and remove useless code in swapchain9

The removed code was there for two reasons:
1) Allow DF16, DF24, INTZ to be used as depth buffer
for swapchain, if the driver doesn't support
PIPE_BIND_SAMPLER_VIEW for the underlying format
2) Set PIPE_BIND_SAMPLER_VIEW if possible, such that
if StretchRect is called on the depth texture, it is happy.

1) The reason these formats needed a workaround is because
the check flags for them in CheckDeviceFormat were incorrect,
which led applications to think the formats were valid for
swapchains, even if they weren't supported.
2) StretchRect limitations for depth buffers force
the resource_copy_region path, which should be fine without
PIPE_BIND_SAMPLER_VIEW.

Thus fix the check for 1), and remove the code.

st/nine: Initial mixed vertex processing support

In mixed vertex processing, the user can enable or disable
software vertex processing. It is on hardware by default.

This feature is not a state, and thus the setting doesn't
need to be recorded by stateblocks.

st/nine: Allocate more space for ATI1

ATIx are "unknown" formats that do not follow block format conventions.
Tests showed that pitch*height bytes are allocated.
apitrace used to depend on this behaviour.
It used to copy more bytes than it has to for the ATI1 block format,
but it didn't crash on Windows.

Increase buffersize for ATI1 to fix this crash.

To implement the feature we copy the ps inputs to a temp array.

This is a feature that is very very rarely used.
