When using any XAAPixmapOps, we call into unknown but freshly
unwrapped callbacks (like fb ones). Unlike the XAA*Fallback calls,
we did so without syncing first, exposing us to all kinds of
synchronisation issues.
I believe that the rendering errors appeared now because *PaintWindow
vanished (e4d11e58), and we just use miPaintWindow instead. This
takes a less direct route to the hw and ends up at
PolyFillRectPixmap, which very often left drawing artifacts.
We now sync accordingly, and no longer get the rendering artifacts i
was methodically reproducing on radeonhd, radeon, unichrome...
Also, in order to allow driver authors to remove extensive syncing
or flushing to hide this issue, create XAA_VERSION_ defines, put
them in xaa.h and bump the patchlevel.

When setting the depth to 24, leave bpp unset so the logic to pick
a supported value is used instead of ignoring the driver's preference
and forcing 32 bpp.

When the linux kernel sets the NX bit vm86 segfaults when it tries to execute
code in memory that is not marked EXEC. Such code gets called whenever
we return from a VBIOS call to signal the calling program that the call
is actually finished and that we are not trapping for other reasons (like
IO accesses).
Use mprotect(2) to set these memory ranges PROT_EXEC.

Works around a silly bug in the kernel that causes wakeup storms after
too many keypresses. Should fix the kernel bug too, but this at least
keeps the idle wakeup count below 1000/sec.

This consists of two parts:
In the implicit server layout, ignore those drivers when looking for a core
device.
And after finishing the server layout, run through the list of devices and
remove any that use mouse or kbd.
AEI is mutually exclusive with the kbd and mouse drivers, so pick either - or.

Usually, the console is set to RAW in the kbd driver. If we hotplug all input
devices (i.e. the evdev driver for keyboards) and the console is left as-is.
As a result, the evdev driver must put an EVIOCGRAB on the device to avoid
characters leaking onto the console. This again breaks many things, amongst
them lirc, in-kernel mouse button emulation and HAL.
This patch sets the console to RAW if AllowEmptyInput is on.
Use-cases:
1. AEI is off
1.1. Only kbd driver is used - behaviour as-is.
1.2. kbd and evdev driver is used: if evdev does not grab the device,
duplicate events are generated.
2. AEI is on
2.1. Only evdev driver is used - behaviour as-is, but evdev does not need
to grab the device anymore.
2.2. evdev and kbd are used: duplicate key events are generated if evdev
does not grab the device.
1.2 is a marginal use-case that can be fixed by adding a "grab" option to the
evdev driver (update of xorg.conf is needed).
2.2 is an issue. If we have no ServerLayout section, AEI is on, but devices
specified in the xorg.conf are still added [1], resulting in duplicate events.
This is a common configuration and needs sorting out.

Some BIOSes (hi XGI!) will attempt to enumerate the PCI bus by asking

If xorg.conf has no ServerLayout section, use the first mouse and
keyboard sections as core devices, even with AllowEmptyInput.
(cherry picked from commit 2eaed4a10f)
Put out a warning if xorg.conf has InputDevice sections, but these aren't
referenced in the used ServerLayout. This is only performed if AllowEmptyInput
is enabled.
The reason behind this is that the server used to auto-add the first
mouse/keyboard sections if none where referenced. Now, with HAL and AEI
enabled by default, setups that relied on this auto-adding break and are left
without input devices. The least we can do is warn them.

In DeleteInputDeviceRequest, leave the conf_idev (which is shared with
xf86ConfigLayout.input) alone for devices that were specified in the
ServerLayout section of the config file. This way, in the next server
generation we are left with what was the original config and can thus re-init
the devices.

If devices are prepended to the list, their wake-up order on resume is not the
same as the original initialisation order. Hot-plugged devices, originally
inited last, are re-enabled before the xorg.conf devices and in some cases may
steal the device files. Result: we have different devices before and after
suspend/resume.

RandR 1.1 has a physical size for each mode. It used to be that the DIX would
remember these modes and pass them back up to the DDX when changing the screen
configuration. The DDX uses RR_GET_MODE_MM to query the driver for the physical
dimensions of the screen, allowing it to preserve the DPI.
With RandR 1.2, the physical dimensions are stored as part of the output, rather
than per mode. The DIX only uses the sizes passed in from the DDX to select the
mode pool for the "default" output, and forgets the physical sizes. Then, when
reconfiguring the screen, it makes up a new RRScreenSizeRec using the dimensions
from the output, screwing up the DPI.
This change works around this problem by ignoring the DIX and querying the real
size from the driver.

This copies over the files generated from mesa/src/mesa/glapi. There's
a corresponding mesa commit that makes it easy to generate the glapi files
straight into the xserver tree when the XML definitions change.
The only few files that are copied from mesa but aren't generated are
glapi.[ch] and glthread.[ch]. Everything in there is technically DRI
driver API and the whole setup is still a bit fragile, but it's not a new
problem.
The --with-mesa-source configure option is still around since other
parts of the server (XGL and DMX - grep for MESA_SOURCE) need that,
but for common case of building with GLX and AIGLX support, that
option is no longer needed.
