a7b97b0fa8 dri2: Fix authentication for < v8 clients (v2).
The legacy logic was embarassingly wrong; AuthMagic should return errno,
so returning FALSE only when AuthMagic returns nonzero is exactly wrong.

v2: Match drmAuthMagic by returning -EINVAL rather than EINVAL
    Fix trailing whitespace

xwayland drivers need access to their screen private data to authenticate.
Now that drivers no longer have direct access to the global screen arrays,
this needs to be passed in as function context.

78f0d9cdc4 dri2: Add DRI2GetParam request (v2)
Bump dri2proto dependency to 2.7.
Bump DRI2INFOREC_VERSION to 7.

This new protocol request effectively allows clients to perform feature
detection on the DDX. The request was added in DRI2 protocol 1.4.

If I had DRI2GetParam in June 2011, when I was implementing support in the
Intel DDX and Mesa for new hardware that required a new DRI2 attachment
format, then I could have avoided a week of pain caused by the necessity
to write a horrid feature detection hack [1] in Mesa. In the future, when
the work begins to add MSAA support to the Intel DDX, having a clean way
to do feature detection will allow us to avoid revisiting and expanding
that hack.

[1] mesa, commit aea2236a, function intel_verify_dri2_has_hiz

v2: If driver doesn't define ds->GetParam, dont' crash. Fall back to
    default behavior, per keithp.

9838b7032e Introduce a consistent coding style
This is strictly the application of the script 'x-indent-all.sh'
from util/modular. Compared to the patch that Daniel posted in
January, I've added a few indent flags:

	-bap
	-psl
	-T PrivatePtr
	-T pmWait
	-T _XFUNCPROTOBEGIN
	-T _XFUNCPROTOEND
	-T _X_EXPORT

The typedefs were needed to make the output of sdksyms.sh match the
previous output, otherwise, the code is formatted badly enough that
sdksyms.sh generates incorrect output.

The generated code was compared with the previous version and found to
be essentially identical -- "assert" line numbers and BUILD_TIME were
the only differences found.

The comparison was done with this script:

dir1=$1
dir2=$2

for dir in $dir1 $dir2; do
	(cd $dir && find . -name '*.o' | while read file; do
		dir=`dirname $file`
		base=`basename $file .o`
		dump=$dir/$base.dump
		objdump -d $file > $dump
	done)
done

find $dir1 -name '*.dump' | while read dump; do
	otherdump=`echo $dump | sed "s;$dir1;$dir2;"`
	diff -u $dump $otherdump
done

e8fd23fad0 dri2: Invalidate DRI2 buffers for all windows with the same pixmap on swap
Without this, when a compositing manager unredirects a fullscreen window which
uses DRI2 and page flipping, the DRI2 buffer information for the compositing

0ce25fd790 dri2: Don't page flip when the window size doesn't match the pixmap size
If the drawable size doesn't match the pixmap size page flipping should
not be allowed.

If the window is larger than the pixmap, page flipping might need to
reposition the CRTC somewhere in the middle of the pixmap. I didn't
spot any code that would handle that at least in the intel driver.

Also the root pixmap could then move to some negative screen
coordinates. Not sure if all bits of code could handle that. Perhaps
when composite is enabled screen_x/y would make it work, but without
composite there's no way that it would work AFAICS.

75beadd766 DRI2/xserver: Don't hang in glXSwapBuffers if drawable moves between crtc's (bug 28383)
Detect if a drawable has been moved from an original crtc to a new crtc
with a lower current vblank count than the original crtc inbetween
glXSwapBuffers() calls. Reinitialize drawable's last_swap_target
before scheduling next swap if such a move has taken place.

last_swap_target defines the baseline for scheduling the next swap.
If a movement between crtc's is not taken into account, the swap may
schedule for a vblank count on the new crtc far in the future, resulting
in a apparent "hang" of the drawable for a long time.

959a1eaf1c composite: use config notify hook to do pixmap resize.
Since reallocating the backing pixmap can fail, we need to try and do
it before any other side effects of reconfiguring the window happen.

This changes the ConfigNotify hook to return status, and moves the
composite window reconfiguration wrappers to ConfigNotify. They all
basically did the same thing, so we can drop the MoveWindow,
ResizeWindow, ChangeBorderWidth wrappers, and allow ConfigNotify to do
all the work. If reallocation fails we fail before we send any
confiureNotify events, or enter the area we can't recover from.

The only place we now enforce 32k limits are in EXA/UXA/fb, so drivers
that don't use this should probably deal with it in their pixmap
allocate if they don't already.

This also breaks ABI, so we need an alternate fix for older servers,
working on the X server makes me realise why I'm a kernel hacker.

e7fae9ecc4 Move each screen's root-window pointer into ScreenRec.
Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.

Since dix uses this data, a screen private entry isn't appropriate.

If we don't have a fake front, nothing will happen.  The fix was extracted
from a bigger patch from Francisco Jerez.

9de0e31746 dri2: Take an XID for tracking the DRI2 drawable
Some pixmaps (window pixmaps and scratch pixmaps) don't have the
drawable->id set and thus DRI2 gets confused when using that field
for looking up the DRI2 drawable.  Go back to using privates for getting
at the DRI2 drawable from a DrawablePtr.  We need to keep the resource
tracking in place so we can remove the DRI2 drawable when the X resource
it was created for goes away.  Additionally, we also now track the DRI2
drawable using a client XID so we can reclaim the DRI2 drawable even if
the client goes before the drawable and doesn't destroy the DRI2 drawable.

1da1f33f2d DRI2: Track DRI2 drawables as resources, not privates
The main motivation here is to have the resource system clean up the
DRI2 drawable automatically so glx doesn't have to.  Right now, the
glx drawable resource must be destroyed before the X drawable, so that
calling DRI2DestroyDrawable doesn't crash.  By making the DRI2
drawable a resource, GLX doesn't have to worry about that and the
resource destruction order becomes irrelevant.

5933b0abc6 DRI2: prevent swap wakes from waking MSC waiters
If a few swaps were queued leading to a throttle related block on the
client, and then the client submitted an MSC wait, one of the previous
swap wakeups could have caused the MSC wait to complete early.  Add a
flag for this to prevent a swap wake from prematurely waking an MSC
waiter.

b00d435ddf DRI2: handle swapsPending better
Avoid a potential swapsPending underflow by incrementing it before
ScheduleSwap, which may complete it immediately.  And be sure to
decrement it again in case the schedule failed.

db1c7cb604 DRI2: advertise lowest supported DRI2 protocol version
Update our supported DRI2 protocol version as each driver does
DRI2ScreenInit, since depending on available kernel features, each DDX
may support different callbacks and therefore protocol.

87ca6320f2 DRI2: handle swap_interval of 0 correctly
A 0 swap interval means that swaps shouldn't be sync'd to vblank, so
just complete the swap immediately in that case.

8476d99231 DRI2: drawable lifetime fixes
Handle drawable destruction and lifetime correctly.

Check whether the drawable priv is valid in DRI2SwapInterval(),
DRI2WaitSBC() and DRI2WaitMSC(); it may have gone away, so be sure to
check it before using it.

If more than 1 outstanding swap is queued, we may complete several after
an app has exited.  If we free it after the first one completes and the
refcount reaches 0, we'll crash the server on subsequent completions.
So delay freeing until all swaps complete and remove the error message
as this is a normal occurence.  To do this properly, we must also avoid
destroying drawables in DRI2DestroyDrawable() if a swap or wait event is
pending.

And finally, make sure we free drawables in DRI2WaitMSCComplete() if
necessary (i.e. if the refcount has reached 0 and this MSC was the last
pending event on the object).

b180e43977 DRI2: fix swapbuffers handling of SBC and target MSC
Returns expected SBC after completion of swap to caller, as required by
OML_sync_control spec, instead of the last_swap_target value.

Passes target_msc, divisor, remainder, correctly for
glXSwapBuffersMscOML() call, while retaining old behaviour for simple
glXSwapBuffers() call.

An OML swap can have a 0 target_msc, which just means it needs to
satisfy the divisor/remainder equation.  Pass this down to the driver as
needed so we can support it.
