This needs to be reviewed once we support screen objects and don't rely
on VRAM for the frame-buffer.
Also fix some integer overflow issues pointed out by Michel Daenzer.

Also make sure all workqueues are idled before the fifo is taken down.

This is to avoid accessing uninitialized data during
drm_irq_uninstall and vblank ioctls. At the same time, enable error check from
drm_kms_init which previously appeared to ignore all errors.

We add an option not to enable fbdev, this option is off (0) by default.
Not enabling fbdev at load time makes it possible to co-operate with
vga16fb and vga text mode when VT switching.
However, if 3D resources are active when VT switching, we're currently
not able to switch over to vga, due to device limitations.
This fixes a bug where we previously lost 3D state during VT switch.

The host may change the layout and, since the change is
communicated to the master, the master needs a way to
communicate the change to the kernel driver.
The minor version number is bumped to advertize the

The host may be touching this part of VRAM at modesetting,
even if we never use it ourselves, since we blit screen updates from 3D
surfaces. Make sure no DMA buffers are placed in this part of VRAM.

The fbdev layer in the kms code should act like a consumer of the kms services and avoid having relying on information being store in the kms core structures in order for it to work.
This patch
a) removes the info pointer/psuedo palette from the core drm_framebuffer structure and moves it to the fbdev helper layer, it also removes the core drm keeping a list of kernel kms fbdevs.
b) migrated all the fb helper functions out of the crtc helper file into the fb helper file.
c) pushed the fb probing/hotplug control into the driver
d) makes the surface sizes into a structure for ease of passing
This changes the intel/radeon/nouveau drivers to use the new helper.

Improve the command verifier to catch all occurences of surface handles,
and translate to SIDs.
This way DMA buffers and 3D surfaces share a common handle space,
which makes it possible for the kms code to differentiate.

This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA.
The driver is under staging the same as Nouveau and Radeon KMS. Hopefully
the 2D ioctls are bug free and don't need changing, so that part of the
API should be stable. But there there is a pretty big chance that the 3D API
will change in the future.
