radeon: avoid using hw pixmaps when we have little VRAM.
This patch returns NULL for pixmap creation when we are using
mixed pixmaps and the pixmap has a size.
The size check is necessary for the front buffer.
We add a flag to force pixmap creation for certain pixmaps
that need to be hw, like the DRI2 and Xv ones.
Idea from Michel and workarounds from Ben Skeggs.
v2: add Option "EXALowVRAM" to allow configuring this, value in MBs.
