Quoting Adam Jackson:
"But the X driver looks like
it never sets MONITOR_EDID_COMPLETE_RAWDATA, which means the X core
doesn't know that any sections beyond the first are present, so it won't
ever hand back more than 128 bytes to clients. Boo."
This patch is based on his.

If the buffer object is tiled, we need to use the fence registers to
perform the appropriate untiling for CPU access. Ensure that we always
take this path for tiled objects, regardless of their size.

This reverts commit 9c3e34703d.
This commit is not ready, as first the driver needs to handle all
controllers, especially those that ignore the BLC and require their own
interface. Fortunately, by moving that discovery into the kernel - where
it just means finding which ACPI device is attached to the video and has a
backlight interface - the userspace code should become much more sane,
and work even with multi-gpu, multi-lid systems.
But that is for tomorrow.
Rather than assert, we should fixup the use of large A1 glyphs. However,
the simplest approach is to simply fallback to s/w.

If the i915 driver exposes a native ACPI interface to modify the panel
backlight use it in preference to the generic interfaces. On multi-GPU
systems, the panel backlight is meant to be connected via the IGP and
this ensures that we always find the right interface.

During -configure we would attempt to query the availablility of KMS
before the DRI module was loaded, thus we were unable to create a valid
bus identifier and so the query failed and we disowned the device.

Marty Jack reported an issue he found where the page-flipping handler
was being lost on server reset. This results in the swap completion
notification being lost, with the sporadic hang of full screen
applications like Compiz, flash and even glxgears!

Dave Airlie advised that hotplug detection can be unreliable and that
mode caching, in general, should be done in the kernel in any case.
This reverts commit 622e600069.
Remember for the detection cycle whether we have already probed for the
EDID -- as this can be slow.

And fixup all the drmmode_* functions to have an intel prefix and

intel_property so that the functions are a little more self-descriptive
and, more importantly, are consistent.

Now that we submit from the flush callback chain, we know we'll always
submit before the client receives the reply or event that blocks it from
rendering the next frame.
There are a few cases where the server will flush client output buffers
but our block handler only catches the most common (before going into select).
If the server flushes client buffers before we submit our batch buffer,
the client may receive a damage event for rendering that hasn't happened yet.
Instead, we can hook into the flush callback chain, which the server will
invoke just before flushing output. This lets us submit batch buffers
before sending out events, preserving ordering.

The kernel overlay code does asynchronous overlay flips. So keep
onto two old buffers, for otherwise the rendering of the next
frame might overwrite the contents of the currently still displaying
one. With ~25fps videos and ~50 Hz screens that's rather unlikely,
still, fix it.

Per-target compilation flags (libIntelXvMC_la_CFLAGS) are required
when multiple targets which require different compiler flags,
are build in the same makefile.
Automake issues a command with -c and -o flags which not all compilers
support. The object fles are prefixed with libIntelXvMC_la.
The macro AM_PROG_CC_C_O must then be used to provide this feature
on compilers that do not have it. If not, a warning is issued at make time.
This macros checks for compiler support and if missing, uses a "compile"
script it generates in the package root directory.
Currently the driver uses per-target flags but the macro is missing.
Rather than adding the macro, this patch stops using per-target flags
by using the AM_CFLAGS variable for all targets in the makefile, as
there is only one.
