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-debug: extend ogl debug capabilities
...
Group opengl calls into a nice name.
Apitrace shows them in a tree format that support folding. Previously it
was a long flat list (10K-40K of lines by frame)
I align the call number with the internal s_n variable. This way it is
easy to map GSdx dump output with the GL debugger :)

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

Extension is a bit slower.
We use it to clear the RT but we generally use it right away so
we don't avoid the FB attachment.

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).

Null is equivalent to a clear to 0.
