2704bdb24a DMX glxproxy: Don't allocate & copy data just to free it unused
Two functions in the DMX glxproxy code loop over all the backend
screens, starting at the highest numbered and counting down to
the lowest.

Previously, for each screen, the code would allocate a buffer
large enough to read the reply from the backend, copy that reply
into the buffer, and then if it wasn't the final screen, free it.
Only the buffer from the final screen is used, to pass on to the
client in the reply.

This modifies it to just immediately discard the responses from
the screens as we loop through it, only doing the allocate & copy
work for the one buffer we pass back to the client.

a3d43edf71 glxproxy: Use _XEatDataWords (from Xlib 1.6) instead of _XEatData
Reduces risk of overflow from converting length field in X replies
from words to bytes.   (Also seems to be what several calls were
already incorrectly passing to _XEatData.)

ea1d76d1b6 Fix formatting of address operators
The formatter confused address operators preceded by casts with
bitwise-and expressions, placing spaces on either side of both.
That syntax isn't used by ordinary address operators, however,
so fix them for consistency.

789d64e19a Remove unneccesary casts from WriteToClient calls
Casting return to (void) was used to tell lint that you intended
to ignore the return value, so it didn't warn you about it.

Casting the third argument to (char *) was used as the most generic
pointer type in the days before compilers supported C89 (void *)
(except for a couple places it's used for byte-sized pointer math).

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

3f3ff971ec Replace X-allocation functions with their C89 counterparts
The only remaining X-functions used in server are XNF*, the rest is converted to
plain alloc/calloc/realloc/free/strdup.

X* functions are still exported from server and x* macros are still defined in
header file, so both ABI and API are not affected by this change.

cb95642dc8 Remove #define NEED_EVENTS and NEED_REPLIES
A grep on xorg/* revealed there's no consumer of this define.

Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.

Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."
