Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=54168
Fix errors introducted in 863d528a9f76d0e8f122aebf19f8564a4c67a938. Said
patch does indeed remove the problematic writes to bad memory, however
it also introduces errors in the algoritm. This patch has the effect of
reverting said patch and adding an if in the proper location to catch
the out of bounds memory write without causing problems to the overall
algorithm.

This is clearly meant to be a fast path, but it appears to be a net
loss at this point.
If you really wanted to ricer-tune here, note that the inner loop of
fbBltOne is a bit too complicated for gcc (at least 4.8.2), it doesn't
specialize the loop for the handful of legal values of bitsPerDst, which
means computing at runtime what could have been const-propped.

A careful read shows that it was always NULL. It hasn't always been; as
the DDX spec indicates, it was the "occluded region that has backing

We have a hack in fb layer for a 24bpp screen to use 32bpp images, and
fbCreateWindow() replaces its drawable.bitsPerPixel field
appropriately. But, the problem is that it always replaces when 32bpp
is passed. If the depth is 32, this results in bpp < depth, which is
actually invalid.
Meanwhile, fbCreatePixmap() has a more check and it creates with 24bpp
only when the passed depth <= 24 for avoiding such a problem.
This oneliner patch just adds the similar check in fbCreateWindow().
This (hopefully) fixes the long-standing broken graphics mess of
cirrus KMS with 24bpp.

We fixed fbCloseScreen to use the FreePixmap function so that the
private counts would be updated correctly during CloseScreen. Xvfb
calls FreePixmap and sets devPrivate to NULL before fbCloseScreen is
called; not checking devPrivate before calling would result in a NULL
pointer dereference.

The width parameter is used to disable the blit fast-path (memcpy) when
source and destination rows overlap in memory. This check was added in [0].
Unfortunately, the calculation to determine if source and destination
lines overlapped was incorrect:
(1) it converts width from pixels to bytes, but width is actually in
bits, not pixels.
(2) it adds this byte offset to dst/srcLine, which implicitly converts
the offset from bytes to sizeof(FbBits).
Fix both of these by converting addresses to byte pointers and width
to bytes and doing comparisons on the resulting byte address.
For example:
A 32-bpp 1366 pixel-wide row will have
width = 1366 * 32 = 43712 bits
bpp = 32
(bpp >> 3) = 4
width * (bpp >> 3) = 174848 FbBits
(FbBits *)width => 699392 bytes
So, "careful" was true if the destination line was within 699392 bytes,
instead of just within its 1366 * 4 = 5464 byte row.
This bug causes us to take the slow path for large non-overlapping rows
that are "close" in memory. As a data point, XGetImage(1366x768) on my
ARM chromebook was taking ~140 ms, but with this fixed, it now takes
about 60 ms.

fb: Fix memcpy abuse
The memcpy fast path implicitly assumes that the copy walks
left-to-right. That's not something memcpy guarantees, and newer glibc
on some processors will indeed break that assumption. Since we walk a
line at a time, check the source and destination against the width of
the blit to determine whether we can be sloppy enough to allow memcpy.
(Having done this, we can remove the check for !reverse as well.)
v3: Convert to byte units
This first checks to make sure the blt is byte aligned, converts all
of the data to byte units and then compares for byte address range
overlap between source and dest.

When fbBresSolid draws a line, it can happen that after the last
pixel, the Bresenham error term overflows, and fbBresSolid paints
another pixel before adjusting the error term.
However, if this happens on the last pixel (len=0), this extra pixel
might overshoot the boundary, and, in rare cases, lead to a segfault.
Fix this issue by adjusting for the Bresenham error term before
drawing the main pixel, not after.

xf86i2c: add pscrn for drivers to use
This just adds a pScrn pointer into the struct for the drivers to use
instead of scrnIndex. Mostly scrnIndex is used for logging, but some
drivers use it to lookup xf86Screens, so let them stash a pScrn instead.
Removing the scrnIndex is a bit more involved and I'm not sure its worth
the effort. Doing i2c in the X server is legacy code as far as I'm concerned.

dix/gc: consolidate GC object creation in one place
The standard GC create and scratch GC create were 90% the same really,
and I have a need in the future for creating GC objects without the
other bits, so wanted to avoid a third copy.

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

The memcpy fast path implicitly assumes that the copy walks
left-to-right. That's not something memcpy guarantees, and newer glibc
on some processors will indeed break that assumption. Since we walk a
line at a time, check the source and destination against the width of
the blit to determine whether we can be sloppy enough to allow memcpy.
(Having done this, we can remove the check for !reverse as well.)
On an Intel Core i7-2630QM with an NVIDIA GeForce GTX 460M running in
NoAccel, the broken code and various fixes for -copywinwin{10,100,500}
gives (edited to fit in 80 columns):
1: Disable the fastpath entirely
2: Replace memcpy with memmove
3: This fix
4: The code before this fix
1 2 3 4 Operation
------ --------------- --------------- --------------- ------------
258000 269000 ( 1.04) 544000 ( 2.11) 552000 ( 2.14) Copy 10x10
21300 23000 ( 1.08) 43700 ( 2.05) 47100 ( 2.21) Copy 100x100
960 962 ( 1.00) 1990 ( 2.09) 1990 ( 2.07) Copy 500x500
So it's a modest performance hit, but correctness demands it, and it's
probably worth keeping the 2x speedup from having the fast path in the
first place.

For fbAdd{Traps,Triangles}() and fbRasterizeTrapezoid() this is just a
matter of adding the image offsets to the trap offsets.
For fbShapes, the story is more complicated:
The recently added pixman API did not allow offsetting
trapezoids. Instead, it would use x_dst and y_dst in such a way that
the effect was to only offset the source image.
In pixman 0.21.8, this API has changed such that all the traps are
conceptually rendered to an infinitely big image, and the source and
destination coordinates are then aligned with (0, 0) of that
image. This means offsetting dst_x and dst_y will now offset the
entire drawing, which is similar to how other composite functions
work.
This patch then changes fbComposite{Triangles,Traps} such that the
source image is aligned with the shapes, and the destination
coordinates offset according to drawable->{x, y}.

These calls no longer go through the CompositePicture() hook, so
damage was no longer generated for them. This patch simply damages the
entire destination clip region.
It would be possible to generate tighter damage for certain operators
such as Over and Add, where blank source pixels have no effect on the
destination, but given that virtually all trapezoid rendering takes
place on pixmaps, it's unlikely that anybody would actually benefit
from this optimization, and the miTrapezoidBounds function did
sometimes show up on profiles, probably because it does several
divisions per trapezoid.
V2: Call DamageRegionProcessPending() - pointed out by Michel Dänzer.
V3: Call DamageRegionProcessPending() *after* rendering -
