gsdx ogl: memory management take 3
...
Add a factor 2 on the VRAM to get the quantity of available memory for the textures.
The driver is allowed to put some textures in RAM. Of course it is bad for performance
but it won't crash.
Due to the 4GB by process limit, I keep a (reasonable) maximum of 3.8GB.
In order to avoid a crash when memory is too low an exception will be risen
with no guarantee on rendering and big performance impact. In this situation
you ought to reduce upscaling/disable large framebuffer.

gsdx ogl: don't use GL_ARB_clear_texture for the depth buffer

It creates some slowdowns for unknown reason. My best hypothesis is
that stencil will be cleared too which is slow.
Let's keep the code for the future when stencil will be dropped.

gsdx ogl: accelerate special case of accurate date.
...
Game often uses date to allow a single pixel pass. If this
use case is detected, stencil buffer will be cleared after first pixels
that pass both depth&stencil test.
It seems to reduce the load on the GPU.
Note: with the help of texture barriere, maybe we could implement the algo
with a single pass.

If a color buffer is still attached and is smaller than depth buffer,
the latter won't be fully cleared.
As a faster alternative, use GL4.4 clear texture function. Avoid to fiddle with
framebuffer and pixel tests.

than an uninitialized alpha value.
