962580a15a treewide: macros lambda-esque screen iteration
iterating over screen list via lambda-esque macros calls like this

    DIX_FOR_EACH_SCREEN({
        do_something
    });

withing the body, the iterator variables `walkScreenIdx` and `walkScreen`
are defined and can be directly used (read-only). the code inside the body
is running in a separate scope.

ca484055c7 dix: unexport screen saver parameters
Not used by any external drivers, so no need to keep them in public

not an ABI change, so can safely be done within ABI-25.

c96901a85a Xext: use calloc() instead of malloc()
Using calloc() instead of malloc() as preventive measure, so there
never can be any hidden bugs or leaks due uninitialized memory.

The extra cost of using this compiler intrinsic should be practically
impossible to measure - in many cases a good compiler can even deduce
if certain areas really don't need to be zero'd (because they're written
to right after allocation) and create more efficient machine code.

The code pathes in question are pretty cold anyways, so it's probably
not worth even thinking about potential extra runtime costs.

232cad9ec3 prevent name clash on Windows w/ RT_* defines
Windows' native headers using some our RT_* define's names for other things.
Since the naming isn't very nice anyways, introducing some new ones
(X11_RESTYPE_NONE, X11_RESTYPE_FONT, X11_RESTYPE_CURSOR) and define the old
ones as an alias to them, in case some out-of-tree code still uses them.

With thins change, we don't need to be so extremely careful about include
ordering and have explicit #undef's in order to prevent name clashes on
Win32 targets.

3360418767 dpms: Consolidate a bunch of stuff into Xext/dpms.c
Most of this is a legacy of the old "extmod" design where you could load
_some_ extensions dynamically but only if the server had been built with
support for them in the first place.

Note that since we now only initialize the DPMS extension if at least
one screen supports it, we no longer need DPMSCapableFlag: if it would
be false, we would never read its value.

8ed0b00fce xfree86: Clean up DPMS support
Rather than setting up a per-screen private, just conditionally
initialize ScrnInfoRec::DPMSSet based on the config options, and inspect
that to determine whether DPMS is supported.

We also move the "turn the screen back on at CloseScreen" logic into the
DPMS extension's (new) reset hook. This would be a behavior change for
the non-xfree86 servers, if any of them had non-stub DPMS support.

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
