With '--disable-debug' we define NDEBUG and so disable the asserts, that
is we continue to default to compiling asserts into the code.

The screen resources are recreated when the screen is rotated as well,
without being finalized. In this case, we do not need to reconstuct the
cache (or if we did, we would need to tear it down first).

In our application, the screen is never rotated from the point of view
of the driver; instead, the compositor applies a suitable rotation as
it composites the display. This works fine on 945, but on 965, videos
are limited in height to the actual height of the screen.
Change various bits of code so that we use the width and height of the
destination pixmap instead of the width and height of the virtual
screen. This works correctly both for XVideo to offscreen storage
(CompositeRedirect) and for XVideo to the screen (no compositor).
added upstream suggestion to error message in case xorg macros or
xserver macros are missing. removed package manager references in
suggestion since these are 'user' and/or 'distribution' preferences.

As it appears that some kernels do indeed return the "wrong" value,
issuing a warning 60 times a second is a cruel and unusual punishment.

There is a race condition between the dri swapbuffers code and
hotplugging whereby we might attempt to execute a wait upon a
non-existent output. This causes a NULL dereference and a loud crash.

As the bo may be pinned for either use by the scanout or through sharing
with another application, under those circumstances we cannot replace
the bo itself but must force the blit for PutImage.

xorg-macros is often package under an unusual name, so provide some
clues as to what name to try on the user's distribution. Installing
build-deps would be just too easy...
Also include a check for the existence of the XORG_DRIVER_CHECK_EXT
macro, otherwise configure might continue in spite of the missing macro
and cause obtuse syntax errors.

Added m4 check for XORG_DRIVER_CHECK_EXT macro definition. Updated m4 fatal messages to give better hint on how to resolve error when xorg macros are missing. Previously, configure would continue in spite of the missing macros and the build would fail for syntax errors.
Implements a consistency check on returned vblank
count values of pageflip completion. Impossible
values are detected, a x-warning is logged and
returned (msc,ust) values are marked invalid,
so clients could perform error handling. Such
a warning would indicate bugs in the pageflip
completion routine of future kms drivers or the
ddx and thereby aid driver debugging.

When a drawable is page-flipped on multiple crtc's (fullscreen
drawable on mirror-mode or multi-head x-screen), only one pageflip
event is finally delivered, after the last participating crtc signals
flip completion, this to avoid visual corruption.
Old code returned vblank count and timestamps of flip completion
of this last crtc, instead of the values of the "master crtc", the
one that was used for initially scheduling/triggering the pagflip
via vblank events. (master = I830DRI2DrawablePipe(drawable))
This patch makes sure that the pageflip completion values of the
"master" crtc are returned, otherwise client applications will
get confused by the random (msc, ust) values returned by whichever
crtc was the last to complete its flip. Without this, the returned
values change randomly and jump forward and backward in time and
count.
