5b86c072d1 Use temporary variables instead of parts of reply structures
When passing variable pointers to functions or otherwise doing long
sequences to compute values for replies, create & use some new
temporary variables, to allow for simpler initialization of reply
structures in the following patches.

Move memsets & other initializations to group with the rest of the
filling in of the reply structure, now that they're not needed so
early in the code path.

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).

c41922940a dix/randr: add a hook into screen to replace scanout pixmap
For DRI2 in some offload cases we need to set a new pixmap on the crtc,
this hook allows dri2 to call into randr to do the necessary work to set
a pixmap as the scanout pixmap for the crtc the drawable is currently on.

This is really only to be used for unredirected full screen apps in composited
environments.

4bf0192d81 randr: fixup constrain to work with slave screens.
Current code constrains the cursor to the crtcs on the master

f2da2c1204 randr: add initial scanout pixmap support (v3)
When randr notices a crtc configuration request for a slave device,
it checks if the slave allocated pixmap exists and is suitable,
if not it allocates a new shared pixmap from the master, shares
it to the slave, and starts the master tracking damage to it,
to keep it updated from the current front pixmap.

If the resize means the crtc is no longer used it will destroy
the slave pixmap.

This adds the concept of a scanout_pixmap to the randr_crtc object,
and also adds a master pixmap pointer to the pixmap object, along
with defining some pixmap helper functions for getting pixmap box/regions.

v2: split out pixmap sharing to a separate function.

v3: update for void *

4ba340cfaa randr: Clean up compiler warnings about unused and shadowing variables
set but not used variables
shadowing a previous local

A hidden problem was that the VERIFY_RR_* macros define local 'rc'

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

9cc44b955b randr: Make the RRConstrainCursorHarder logic the same as miPointerSetPosition
The constraining logic in RRConstrainCursorHarder allows the cursor to reach
crtc positions of x = width and y = height while the constraining code in
miPointerSetPosition only allows it to reach x = width - 1 and y = height - 1
for the analogous screen case.

This patch makes the former's logic equivalent to the latter's which allows
applications to benefit from Fitts's law. E.g. a maximized application
adjacent to a crtc border wouldn't get pointer events if the user moved the
pointer all the way until it's contained.

c7e4222c9a randr: set error numbers of resource types in RRExtenstionInit() (V2)
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=30367

Currently the ddx calls xf86RandR12Init()
  (-> RRScreenInit()
     -> RRInit()
       -> RRModeInit()
       -> RRCrtcInit()
       -> RROutputInit())
before RRExtensionInit() is called. This causes RRErrorBase
being 0 while setting resource type error values (resource types:
RROutput, RRMode and RRCrtc). The fix moves the setting of error
values to own functions which are called in RRExtensionInit()
to get the right RRErrorBase.

V2: With header file

49f77fff14 Rework symbol visibility for easier maintenance
Save in a few special cases, _X_EXPORT should not be used in C source
files. Instead, it should be used in headers, and the proper C source
include that header. Some special cases are symbols that need to be
shared between modules, but not expected to be used by external drivers,
and symbols that are accessible via LoaderSymbol/dlopen.

  This patch also adds conditionally some new sdk header files, depending
on extensions enabled. These files were added to match pattern for
other extensions/modules, that is, have the headers "deciding" symbol
visibility in the sdk. These headers are:
o Xext/panoramiXsrv.h, Xext/panoramiX.h
o fbpict.h (unconditionally)
o vidmodeproc.h
o mioverlay.h (unconditionally, used only by xaa)
o xfixes.h (unconditionally, symbols required by dri2)

  LoaderSymbol and similar functions now don't have different prototypes,
in loaderProcs.h and xf86Module.h, so that both headers can be included,
without the need of defining IN_LOADER.

  xf86NewInputDevice() device prototype readded to xf86Xinput.h, but
not exported (and with a comment about it).

d6cbd4511e Export symbols defined in the sdk.
This is the biggest "visibility" patch. Instead of doing a "export"
symbol on demand, export everything in the sdk, so that if some module
fails due to an unresolved symbol, it is because it is using a symbol
not in the sdk.

  Most exported symbols shouldn't really be made visible, neither
advertised in the sdk, as they are only used by a single shared object.

  Symbols in the sdk (or referenced in sdk macros), but not defined
anywhere include:
