01e18af17f rrcrtc: brackets are hard, lets go shopping.
Slaving two outputs on a secondary GPU to a primary GPU testing

wrong thing, then as usual segfault in the rotation code.

caf1dec2a7 V2: Add check for link from output to crtc before optimizing out a CrtcSet call
The function RRCrtcSet call checks to see if the config being set is
already configured, but, doesn't check that the selected outputs are
connected to the crtc before skipping.  This means that the following
sequence will omit the final CrtcSet call to the driver:

    CRTC c1 connect to output o
    CRTC c2 connect to output o
    CRTC c1 connect to output o

This change adds the check to ensure that each of the calls are made to
the driver.

7115f6c709 randr: unref the provider shared pixmap the appropriate number of times
When an RandR shared pixmap is created in rrCreateSharedPixmap, it has a refcnt
of 1.  Then, PixmapShareToSlave bumps the refcnt to 2.  However, there's no
corresponding PixmapUnshareFromSlave where the refcnt can be decreased again,
and there's no convenient common place where the refcnt can be decremented when
the slave pixmap is destroyed.

Fix this by just unreffing the pixmap twice in RRCrtcDetachScanoutPixmap.

this hook allows dri2 to call into randr to do the necessary work to set

This is really only to be used for unredirected full screen apps in composited

f2da2c1204 randr: add initial scanout pixmap support (v3)
When randr notices a crtc configuration request for a slave device,
it checks if the slave allocated pixmap exists and is suitable,
if not it allocates a new shared pixmap from the master, shares
it to the slave, and starts the master tracking damage to it,
to keep it updated from the current front pixmap.

If the resize means the crtc is no longer used it will destroy
the slave pixmap.

This adds the concept of a scanout_pixmap to the randr_crtc object,
and also adds a master pixmap pointer to the pixmap object, along
with defining some pixmap helper functions for getting pixmap box/regions.

v2: split out pixmap sharing to a separate function.

v3: update for void *

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

9cc44b955b randr: Make the RRConstrainCursorHarder logic the same as miPointerSetPosition
The constraining logic in RRConstrainCursorHarder allows the cursor to reach
crtc positions of x = width and y = height while the constraining code in
miPointerSetPosition only allows it to reach x = width - 1 and y = height - 1
for the analogous screen case.

This patch makes the former's logic equivalent to the latter's which allows
applications to benefit from Fitts's law. E.g. a maximized application
adjacent to a crtc border wouldn't get pointer events if the user moved the
pointer all the way until it's contained.

c7e4222c9a randr: set error numbers of resource types in RRExtenstionInit() (V2)
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367

Currently the ddx calls xf86RandR12Init()
  (-> RRScreenInit()
     -> RRInit()
       -> RRModeInit()
       -> RRCrtcInit()
       -> RROutputInit())
before RRExtensionInit() is called. This causes RRErrorBase
being 0 while setting resource type error values (resource types:
RROutput, RRMode and RRCrtc). The fix moves the setting of error
values to own functions which are called in RRExtensionInit()
to get the right RRErrorBase.
