Keith Packard 52048ce29f Xext/saver: Swap ScreenSaverSuspend 'suspend' field. Handle old XCB clients.
This field was defined as a Bool in the protocol headers and BOOL in
xcb. Bool is not a valid type for protocol fields. It is defined as
'int' by Xdefs.h, which we expect to be 32-bits on all machines.

The protocol headers and xcb have patches posted to switch to CARD32,
which is at least well defined.

This change adds the necessary byte swapping to handle other-endian
clients with this 32-bit field, and then changes the request
processing to compare all 32-bits against zero so that it works with
both new and old clients.

On MSB machines, Xlib will continue to work properly, but old XCB will
not interoperate with the X server (either before or after this patch).

Adam Jackson 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.

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

Jamey Sharp e7fae9ecc4 Move each screen's root-window pointer into ScreenRec.
Many references to the WindowTable array already had the corresponding
screen pointer handy, which meant they usually looked like
"WindowTable[pScreen->myNum]". Adding a field to ScreenRec instead of
keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.

Since dix uses this data, a screen private entry isn't appropriate.

xf86-video-dummy currently uses WindowTable, so it needs to be updated

Jamey Sharp 4b9600a416 Make WriteEventsToClient/WriteToClient no-op on fake or dead clients.
This matches the test in TryClientEvents, and is a superset of tests
done by the callers of these functions. The consequence of forgetting
these tests is a server crash, so they're always desirable. In my
opinion, it's better to not require the callers to remember to do these
checks.

For callers that don't do very much work before calling WriteToClient or
WriteEventsToClient, I've removed the redundant checks.

hw/xquartz/xpr/appledri.c has an interesting case: While its check for
"client == NULL" appears redundant with the test in WriteEventsToClient,
it dereferences client to get the sequence number.
