Windows disables hw pointer acceleration and draws the cursor
in frame buffer if the driver does not report pointer capabilities
in QueryAdapterInfo. In this mode OS usually does not send pointer
commands to the driver or does it with pointer set to invisible
state. This mode of operation consumes CPU time and device-to-host
traffic. Now we enable pointer hardware acceleration.

This make sure that these function goes into the non
paged section.
Also this change is much shorter than marking code if
can be paged as almost code can be paged.
It's also coherent with other source files.

When qxl revision is 3, the vga driver is the one that is running.
While installing the driver the function VgaDevice::HWInit
has displayInfo structure zeroed out. The displayInfo should be
initialized using DxgkCbAcquirePostDisplayOwnership and thus it
should be called before calling HWInit.
Please note that we can't just move the call to "DxgkCbAcquirePostDisplayOwnership"
before calling HWInit as the m_Id isn't initialized for QxlDevice until the call to HWinit is over.
This patch fixes a bug similar to the one found here:
https://bugzilla.redhat.com/show_bug.cgi?id=1202267
However this one occurs when installing the driver.

Framebuffer should only be used in VGA mode, as WDDM DOD
driver doesn't use the frame buffer (bar0), so no
reason to map in into memory. However the mode is only known
at runtime therefore framebuffer logic should be active when the
driver is operating in vga mode only.
There were rare BSOD failures when the mapping failed.

This patch adds support for arbitrary resolution and updating
monitor configurations using custom ioctls.
This patch doesn't make any restriction for minimal resolution at all
as Windows can handle low resolution just fine, moreover the old (XPDM)
driver behaves like this too.

As documented in MSDN, "DxgkDdiPresentDisplayOnly" should copy
each "move rectangle" from a given source point in the source buffer
to the destination. The current implementation doesn't take into account
the shift of the given source point at all. This patch fixies the issue.
