Adam Jackson dc7ceda90f dispatch: Mark swapped dispatch as _X_COLD
This touches everything that ends up in the Xorg binary; the big missing
part is GLX since that's all generated code. Cuts about 14k from the
binary on amd64.

Alan Coopersmith 73c63afb93 Xi: unvalidated lengths in Xinput extension [CVE-2014-8095]
Multiple functions in the Xinput extension handling of requests from
clients failed to check that the length of the request sent by the
client was large enough to perform all the required operations and
thus could read or write to memory outside the bounds of the request
buffer.

This commit includes the creation of a new REQUEST_AT_LEAST_EXTRA_SIZE
macro in include/dix.h for the common case of needing to ensure a
request is large enough to include both the request itself and a
minimum amount of extra data following the request header.

Keith Packard 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

Eamon Walsh 00bc8d34c6 Xi: check for Use permission on the device in SetClientPointer().
Presumably, some intelligent, XI2-aware management app will be calling
XISetClientPointer on behalf of other clients; this check makes sure
the target client has permission on the device.

Requires changing the prototype to return status code instead of Bool.

Eamon Walsh 119b966677 Xi: fix up access modes for calls to dixLookupDevice().
New access modes are being passed to the device access hook for XI2:
DixCreateAccess for creating a new master device;
DixAdd/RemoveAccess for attaching/removing slave devices to a master; and
DixListProp/GetProp/SetPropAccess for device properties.

Refer to the XACE-Spec document in xorg-docs, section "Device Access."

Peter Hutterer 17f9723f48 input: bump to ints for deviceids - XI2 requires 16-bit deviceids.
Note: ABI break, but ABI_XINPUT_VERSION has NOT been bumped. Recompile input
drivers.

Peter Hutterer d230742ea8 Xi: namespace XI2 files.
Some files (notably those merged with MPX before XI2 came along) didn't use
a 'xi' prefix. This patch changes all of them to meaningful names.
