Explain that AIGLX is normally expected to fail and the users should
not really worry about it. Also provide a warning in the case if the
driver has been compiled without libUMP support (it could be that
the user actually wanted 3D acceleration, but just has not installed
all the needed dependencies).

This initial G2D support code can speed up moving windows in XFCE. Currently
disabled by default, but can be enabled by editing /etc/X11/xorg.conf and
adding the following line to the "Device" section:

        Option          "AccelMethod" "G2D"

Avoid creating a new mapping because that's a waste of the virtual address
space. Also we are going to use this xserver framebuffer mapping address
for testing whether window backing pixmaps are allocated in the framebuffer
and can be accelerated by G2D.

The driver can use sunxi display controller layers for fully visible
windows, avoiding expensive memory copy.

Hardware cursor is necessary because it is also visible on
top of sunxi disp layers, while software cursor is not.

FIXME: there is one minor problem with negative cursor
positions. The hardware does not support them, so such
positions are just set to 0 for now. In the future this
can be solved better by changing the cursor picture and
showing only the parts which are visible on screen.

Note: the header file "sunxi_disp_ioctl.h" is GPL licensed. So until
it is gets a MIT/X11 replacement, the DDX driver is GPL licensed as
a whole. The individual source files still have their own license.
Also in order to avoid any possible confusion, the MIT/X11 license
header from COPYING has been added to "fbdev.c" and "fbdev_priv.h".

It is going to be included by multiple different source files.

As there is no way for the hardware specific bits to be accepted
in xf86-video-fbdev, we need a new driver with its own name.

To build VESA driver for use with pci-rework Xserver, add --enable-pciacces
to the configure command line.  Otherwise, the "traditional" VESA driver will
be built.

We were determining it from the mode which is current at X server startup,
which may have a completely different pitch.

Based on Adam Jackson's shadow framebuffer fixes in xf86-video-vesa.

    #5460 (Kevin Martin), and apply fix for miext/shadow crasher
    https://bugs.freedesktop.org/show_bug.cgi?id=6940 (Kristian Hoegsberg).
