If screen targets are enabled and there is a reasonable chance that the vmwgfx
drm driver can use the surface backing a pixmap as a screen target surface,
then make that surface a modesetting framebuffer rather than the corresponding
DMA buffer. In practice this applies when we start scanning out from the
origin (0,0) of the pixmap. However, we would also like to apply the constraint
that the scanout area is the entire pixmap, since that is the constraint used
by the drm driver, but that would currently require drm framebuffer
reallocations and possible flicker, so disable that for now. The drm driver
will correctly handle the possibly oversized surface handed to it anyway, and
the cost we pay for this is an extra hardware copy of the dirtied area when
doing a software update of the scanout.

In a multimon environment, the cursor would sometimes disappear on the
newly enabled screen. Fix this.

Part of freedesktop.org bugzilla bug #80645
If taking a scanout reference on a pixmap fails, the
struct vmwgfx_screen_entry::pixmap pointer must be set to NULL, otherwise
the driver will incorrectly attempt to remove the scanout reference in the
error path, causing a segfault.
This problem is seen in the above-mentioned bug, but it is not the root
cause of the problem. With this patch applied, the server will terminate
cleanly instead of segfaulting.

The kernel now takes care of doing this the right way;
no need to duplicate that functionality.

This imports the vmwgfx driver, based on the Gallium3D Xorg state tracker,
as well as the saa library. A "Shadow Acceleration Architecture", which is
optimized for the case where transfers between system (shadow) and hw memory
is very costly.
