This patch only changes the API, not the implementation of the
devPrivates infrastructure. This will permit a new devPrivates
implementation to be layed into the server without requiring
simultaneous changes in every devPrivates user.

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
to reflect this change.

Oliver McFadden reports that the invisible cursor sprite caused damage
events and thus unnecessary redrawing, so removing it improves
performance when using software cursor sprites, especially on those
devices where you do not want a visible cursor: touchscreen tablets,
embedded devices, etc.
For the xfree86 DDX, if hardware cursors are used, the driver is
required to provide a HideCursor function, which will be called instead
of trying to set a null cursor. I think software cursors are already
safe. The other DDXes also look safe.
As far as I can tell, there's no reason to realize a null cursor. I
think everything that handles null cursors doesn't rely on any setup in
RealizeCursor, and treats them as empty cursors.
Xnest assumes that if a cursor is created, it will be realized before it
is freed, which didn't happen if the invisible cursor was never used in
a server generation. So this fixes a segfault in Xnest as well.

Rather than always returning BadValue, associate an error status like
BadWindow with a resource type like RT_WINDOW, and return the
appropriate one for the requested type.
This patch only touches the core protocol resource types. Others still
return BadValue and need to be mapped appropriately.
dixLookupResourceByType can now return BadImplementation, if the caller
asked for a resource type that has not been allocated in the server.

TryClientEvents already did this; this commit just moves the assignment
one level down so that no event source has to worry about sequence

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.

The only remaining X-functions used in server are XNF*, the rest is converted to

X* functions are still exported from server and x* macros are still defined in

This uses the same hack that dix uses for the rootCursor -- allocate
a resource ID for the invisible cursor so that it gets freed at reset
time. This also allows us to unconditionally create it during
extension initialization; necessary as the privates layout may well be
different on subsequent generations.

The screen's DisplayCursor func is wrapped as
AnimCurDisplayCursor -> CursorDisplayCursor -> miPointerDisplayCursor.
Calling CursorDisplayCursor while an animated cursor was currently displayed
would remove AnimCurDisplayCursor from the wrap stack. Thus, the next call
to ChangeToCursor wouldn't update the animated cursor state. The block
handler for animated cursors would then continuously overwrite the actual
cursor, leaving an animated cursor everywhere on the screen.

For embedded use, it's convenient to be able to disable the cursor
completely, without having to audit and fix up all your third-party
code (e.g. Mozilla Firefox).
Add -nocursor and -cursor server options to enable and disable the
cursor. The default is still -cursor, but embedded users can run the
server with -nocursor to hide the cursor regardless of what
application developers do.

dixLookupResource attempted to automatically detect whether the caller
wanted a lookup by-type or by-class, unfortunately, it guessed wrong for
RT_NONE. Instead of trying to make the guess better, this patch just reverts
the unification and creates separate functions for each operation.
Changes MakeAtom to take a const char * and NameForAtom to return them,
since many callers pass pointers to constant strings stored in read-only
ELF sections. Updates in-tree callers as necessary to clear const

AllocARGBCursor realizes the cursor but can only do so if we have devices
there already. If we don't - then the cursor needs to be realized elsewhere.
This is usually done in InitializeSprite, but since xfixes just hard-swaps the
(realized) cursor to the InvisibleCursor, we need to manually realize it
before trying to display it.
The intended behaviour was "show as soon as someone calls
XDefineCursor". What you actually got was, uh, slightly less well
defined, since the screen's ChangeWindowAttributes hook would run after
DIX handled the cursor change. Oops.
The trivial way to turn the cursor on is:
% xsetroot -cursor_name gumby
Refer to /usr/include/X11/cursorfont.h for cursor names.
Thanks to anholt for catching this.
Yes, this means the server will start without showing a cursor. Pretty
much any application that wants to interact with the mouse will define
cursors, so this essentially just delays showing it until gdm (or
whatever) loads.

Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
Freeing resources during client closedown can cause cursor changes which
attempt to send cursor events through the XFixes extension; a client in the
process of closing down has no file to send events to, causing a crash when
this path is hit.
