02e18c9fb5 X Sync Cleanups
Various cleanups identified during review of the
X Sync Fence Object patches.

-Correctly handle failure of AddResource()

-Don't assert when data structures are corrupt.  Instead,
 use a new helper function to check for counter sync
 objects when they're expected, and warn if the type is
 wrong.

-Use the default switch label rather than reimplementing
 it.

-Re-introduce cast of result of dixAllocateObjectWithPrivate()
 to kill an incompatible pointer type warning.

-Remove comments claiming protocol updates are needed.  One
 wasn't true and the other was addressed with a xextproto
 change.

-Return BadFence, not BadCounter from XSyncAwaitFence()

397dfd9f87 Create/Destroy/Trigger/Reset/Query Fence Sync objs
Initial server side implementation of fence sync
objects.  Allows creation, management, and state
queries of binary state objects.  Currently they
are not very useful as there is no way to wait for
them efficiently.

The basic trigger operation added here triggers
relative to a given X screen's rendering operations.
To perform this operation, fence sync objects must
be tied to a screen.  As Aaron Plattner pointed out,
screens are identified but a drawable in X protocol,
so a drawable argument is included in
XSyncCreateFence().  The screen also could have been
specified as part of the trigger operation.  However,
it is also desireable to associate a screen with
fence sync objects at creation time so that the
associated screen's driver can allocate any HW-
specific resources needed by the fence object up
front.

675f4a8525 Abstract valuator masks through a set of APIs.
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.

This patch was initially written by Chase Douglas.

2dc138922b Rename region macros to eliminate screen argument
This is a combination of a huge mechanical patch and a few small
fixups required to finish the job. They were reviewed separately, but
because the server does not build without both pieces, I've merged
them together at this time.

The mechanical changes were performed by running the included
'fix-region' script over the whole tree:

$ git ls-files | grep -v '^fix-' | xargs ./fix-region

And then, the white space errors in the resulting patch were fixed
using the provided fix-patch-whitespace script.

$ sh ./fix-patch-whitespace

Thanks to Jamey Sharp for the mighty fine sed-generating sed script.

The hand-done changes involve removing functions from dix/region.c
that duplicate inline functions in include/regionstr.h, along with
their declarations in regionstr.h, mi.h and mispans.h.

This fuses two loops in each function, eliminating an intermediate
MAXSCREENS-sized array from each.

Aside from being more efficient, I believe this is equivalent to the

  and

8033fb6c97 Set event sequence number in WriteEventsToClient instead of at callers.
TryClientEvents already did this; this commit just moves the assignment
one level down so that no event source has to worry about sequence
numbers.

...No event source, that is, except XKB, which inexplicably calls
WriteToClient directly for several events.

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.
