This is clearly meant to short-circuit the (modestly) expensive resource
lookup in LegalNewID. The problem is that long-lived clients will
eventually run completely through their XID space and start asking
XC-MISC for IDs to reuse. Once that happens, the comparison against
expectID will always be true, and we'll no longer catch XID collisions
at all.

Rename compUpdateWindow to compPaintWindowToParent and split the child
walk to compPaintChildrenToWindow. Calling compPaintChildrenToWindow
allows an arbitrary subtree to be updated, instead of having to update
all the windows. This will be used to make sure all the descendants are
copied to the parent when the parent window contents need to be accessed
in IncludeInferios sub-window mode.
WindowRec has a new member 'damagedDescendants' that is used to keep
track of which subtrees need updating. When a window is damaged,
'damagedDescendants' will be set for all the ancestors, and when a
subtree is updated, the tree walk can be stopped early if no damaged
descendants are present.
CompScreenRec no longer needs the 'damaged' member since the root
window's 'damagedDescendants' provides the same information.

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);

The XI2 protocol supports per-axis modes, but the server so far does
not. This change adds support in the server.
A complication is the fact that XI1 does not support per-axis modes.
The solution provided here is to set a per-device mode that defines the
mode of at least the first two valuators (X and Y). Note that initializing
the first two axes to a different mode than the device mode will fail.
For XI1 events, any axes following the first two that have the same mode
will be sent to clients, up to the first axis that has a different mode.
Thus, if a device has relative, then absolute, then relative mode axes,
only the first block of relative axes will be sent over XI1.
Since the XI2 protocol supports per-axis modes, all axes are sent to the
client.

This commit introduces an abstraction API for handling masked valuators. The
intent is that drivers just allocate a mask, set the data and pass the mask
to the server. The actual storage type of the mask is hidden from the
drivers.
The new calls for drivers are:
valuator_mask_new() /* to allocate a valuator mask */
valuator_mask_zero() /* to reset a mask to zero */
valuator_mask_set() /* to set a valuator value */
The new interface to the server is
xf86PostMotionEventM()
xf86PostButtonEventM()
xf86PostKeyboardEventM()
xf86PostProximityEventM()
all taking a mask instead of the valuator array.
The ValuatorMask is currently defined for MAX_VALUATORS fixed size due to
memory allocation restrictions in SIGIO handlers.
For easier review, a lot of the code still uses separate valuator arrays.
This will be fixed in a later patch.

Without this patch, any negative valuator value is wrong when returned
from XQueryDeviceState(). This is a regression from at least xserver
1.4.
Valuator data is set in dix/getevents.c:set_valuators() by copying
signed int values into an unsigned int field
DeviceEvent.valuators.data.
That data is converted into a double with an implicit cast by
assignment to axisVal[i] in Xi/exevents.c:UpdateDeviceState().
That double is converted back to a signed int in
queryst.c:ProcXQueryDeviceState(). If the original value in
set_valuators() is negative, the double value will be > 2^31 and the
conversion back to a signed int is undefined. (Although I
consistently see the value -2^31.)
Fix this by changing the definition of DeviceEvent.valuators.data from
uint32_t to int32_t.
