composite: use config notify hook to do pixmap resize.
Since reallocating the backing pixmap can fail, we need to try and do
it before any other side effects of reconfiguring the window happen.
This changes the ConfigNotify hook to return status, and moves the
composite window reconfiguration wrappers to ConfigNotify. They all
basically did the same thing, so we can drop the MoveWindow,
ResizeWindow, ChangeBorderWidth wrappers, and allow ConfigNotify to do
all the work. If reallocation fails we fail before we send any
confiureNotify events, or enter the area we can't recover from.
The only place we now enforce 32k limits are in EXA/UXA/fb, so drivers
that don't use this should probably deal with it in their pixmap
allocate if they don't already.
This also breaks ABI, so we need an alternate fix for older servers,
working on the X server makes me realise why I'm a kernel hacker.

dix: adds support for none root window background
It lets the driver notify the server whether it can draw a background when
'-background none' option is used by the system platform. Use cases for that
could be video drivers performing mode-setting in kernel time, before X is up,
so a seamless transition would happen until X clients start to show up.
If the driver can copy the framebuffer cleanly then it can set the flag
(canDoBGNoneRoot), otherwise the server will fallback to the normal behaviour.
The system must explicit indicates willingness of doing so through
'-background none'. We could do this option as default; in such case,
malicious users would be able to steal the framebuffer with a bit of tricks.
For instance, I can see the content of my nVidia Quadro FX 580 framebuffer
old X session modifying a bit nv driver:
xf86DPMSInit(pScreen, xf86DPMSSet, 0);
- /* Clear the screen */
- if(pNv->xaa) {
- /* Use the acceleration engine */
- pNv->xaa->SetupForSolidFill(pScrn, 0, GXcopy, ~0);
- pNv->xaa->SubsequentSolidFillRect(pScrn,
- 0, 0, pScrn->displayWidth, pNv->offscreenHeight);
- G80DmaKickoff(pNv);
- } else {
- /* Use a slow software clear path */
- memset(pNv->mem, 0, pitch * pNv->offscreenHeight);
- }
+ pScreen->canDoBGNoneRoot = TRUE;

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).
