gsdx-ogl: don't use extra shader for sprite hack
...
Atst == 2 && sprite_hack is equivalent to Atst == 1
It frees a bit in the shader selector, and reduces shader combinations.

gsdx-ogl: fix logz management (FFXII)

The issue is that z+1 overflow if z is UINT max
log2(z) overflow if z is 0
So let's use an or 1 to avoid both overflow

gsdx-ogl: improve date performance for GL45
...
If there is no overlap, it is allowed to directly read from the render target.
On SotC testcase with 6x scaling: 30fps -> 40fps
Note: it requires GL_ARB_texture_barrier extension so be sure to have a recent driver
Note2: it requires a lots of testing too
Open question: in case of complex date (written alpha)
Will it be faster to split the draw call into multiple call with no
primitive overlap

gsdx-ogl: implement a new hack UserHacks_UnscaleSprite for opengl
...
UserHacks_UnscaleSprite = 1 will unscale flat sprites
UserHacks_UnscaleSprite = 2 will unscale all sprites (don't work well so far)
The idea of the hack is to redo the interpolation of texture coordinate
based on the non-upscaled pixel position.
It avoids various glitches but sprites aren't upscaled anymore (so no
more anti-aliasing, potentially a coefficient can be added).
