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: increase buffer to have crash in case of overflow
...
Avoid a crash on Onimusha3 (PAL 60HZ)
In theory it will be better to find the root cause of overflow. I.e. somewhere in this
code below. Dirty rectangle is too big.
***********************************************************************
if(rowsize > 0 && offset % rowsize == 0)
{
int y = GSLocalMemory::m_psm[psm].pgs.y * offset / rowsize;
if(r.bottom > y)
{
GL_CACHE("TC: Dirty After Target(%s) %d (0x%x)", to_string(type),
t->m_texture ? t->m_texture->GetID() : 0,
t->m_TEX0.TBP0);
// TODO: do not add this rect above too
t->m_dirty.push_back(GSDirtyRect(GSVector4i(r.left, r.top - y, r.right, r.bottom - y), psm));
t->m_TEX0.TBW = bw;
continue;
}
}
***********************************************************************
So as a temporary solution (that will likely stay for a couple of
years), buffers were increased.

gsdx-ogl: use the standard openGL name

Function pointer was mangled to avoid any collision. Nowadays all symbols
are hidden so no risk of collision.
Syntax is nicer beside it would allow to put back GLES3.2. I think it
supports most of the used extension.
glActiveTexture & glBlendColor are provided without symbol query.
