util/gl: add default window config of 150 x 150 pixels

On Win7 windows get resized to the min size of 116x100 pixels (which
might depend on the Aero theme, etc).  This resize is detected by
the piglit framework:

Got spurious window resize in automatic run (100,100 to 116,100)
PIGLIT: {'result': 'warn'}

so we get a 'warn' result instead of actually running the test.

This sets a default window size of 150x150 pixels.  Next, we'll
remove the "config.window_width/height = 100" lines from a bunch
of tests.

Use the default from piglit-framework-gl.h

No regressions seen with new size.

fbo-gl_pointcoord: remove config.window_width/height and fix asst. bugs

The size of the window and the size of the FBO were mixed up in a few
places.  Add missing FBO binding calls so the window can be resized.
Use an rb_size variable instead of hard-coded 100.

cubemap-shader: add a cubemap test that checks for lod related issues

While adding cube map arrays to r600g I noticed no test actually tested
whether the explicit lod or lod bias on cubemaps was actually being
used. This test is a variant on the cubemap test that contains 3 variants,

plain cubemap with shader,
cubemap sampling with lod bias
cubemap sampling with explicit lod.

This test currently fails on r600g due to the bug, which I shall fix soon.

Revert "arb_texture_cube_map_array: textureSize only applies to samplerCubeArray."

This reverts commit ccde8c37c2c1eb7d1b1b7451677b9f6ce9237591.

after talking to Kayden we should always test for this.
