gsdx-ogl: add a texture offset uniform parameter to vertex shader
...
It would be used for a new implementation of the half pixel offset hack
Hopefully it doesn't badly impact the perf on low end iGPU

gsdx ogl: rework atst handling
...
* Move the rounding operation in the constant buffer
* Merge less with less equal. And merge greater with greater equal
Need test

glsl: optimize the number of active constant buffer
...
Increase the performance on the free driver (Nouveau)
Currently the driver validates all UBO when only 1 is updated. It
is clearly a bad idea to put all UBO in a single common headers.

gsdx ogl: replace 4 VS shader variation by an AND mask
...
Perf will be roughly the same. However there is a single VS for all
the HW emulation.

gsdx ogl: Extend uniform buffer with channel parameter
...
Instead to use the standard ps ubo which is used every draw call.
I reused a barely used buffer to reduce the extra cost of the upload

* avoid duplication between all the files for UBO
* remove various interface define
