Enrico Weigelt, metux IT consult 7a2a5bd692 xfixes: simplify dispatcher
The dispatcher functions are much more complex than they're usually are
(just switch/case statement). Bring them in line with the standard scheme
used in the Xserver, so further steps become easier.

It's also much cleaner to use the defines from proto headers instead of
raw numbers.

Not used in any external modules, so no need to keep it public.

Enrico Weigelt, metux IT consult eea9e4e84b xfixes: drop swapping request length fields
The request struct's length fields aren't used anymore - we have the
client->req_len field instead, which also is bigreq-compatible.

Enrico Weigelt, metux IT consult a917f6a8a8 drop obsolete HAVE_DIX_CONFIG_H
The symbol controls whether to include dix-config.h, and it's always set,
thus we don't need it (and dozens of ifdef's) anymore.

This commit only removes them from our own source files, where we can
guarantee that dix-config.h is present - leaving the (potentially exported)
headers untouched.

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.

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

change it to simple 'map'.
