When the framebuffer is a vmwgfx dma buffer and a proxy surface is
created, the vmw_kms_update_proxy() function requires that the proxy
surface width and the framebuffer pitch are compatible, otherwise
display corruption occurs as seen in gnome-shell/native with software
3D. Since the framebuffer pitch is determined by user-space, allocate
a proxy surface the width of which is based on the framebuffer pitch
rather than on the framebuffer width.

This patch fixes a kernel panic issue which happened
when drm driver is closed while modetest.

This issue could be reproduced easily by launching modetest
with page flip repeatedly.

The reason is that invalid drm_file object could be accessed by
send_vblank_event function when finishing page flip if the drm_file
object was removed by drm_release and there was a pended page
flip event which was already committed to hardware.

So this patch makes the pended page flip event to be cancelled by
preclose callback which is called at front of drm_release function.

Changelog v2:
- free vblank event objects belonging to the request process,
  increment event space and decrease pending_update when cancelling
  the event

'zpos' plane property is configurable, so adjust hardware layers
priority based on the zpos value. 'zpos' value shifted by one can be
used directly as hw priority value and stored to the registers, because
mixer accepts priority values from 1 to 15 (0 means that layer is
disabled).

This patch also changes the default layer priority to match already
exposed initial zpos values. The initial configuration is now:
[top] video > gfx layer1 > gfx layer0 [bottom].
