winsys/svga: Rework buffer allocation to make it more robust v2.
Don't allow any "CPU" buffers to be allocated by the pb_fenced buffer manager, since we can't protect against failures during buffer validation. Also, add an extra slab buffer manager to allocate buffers from the kernel if there is a failure to allocate from our big buffer pool. The reason we use a slab manager for this, is to avoid allocating many very small buffers from the kernel. v2: Increased VMW_MAX_BUFFER_SIZE and fixed some comments.
