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.

$ 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.

This matches the test in TryClientEvents, and is a superset of tests

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.

store the actual master device's id (since it is constant for the life of
the device anyway).
Callers should use GetXtstDevice now instead of digging around in the
devPrivates themselves.
This patch allows for a cleanup in the creation of new master devices since
GetMaster and GetXtstDevice spare the need for loops, IsPointer checks and
similar.

isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.
Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.
This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).
This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).

A XTest virtual slave device pair (kbd/ptr) exists for every master
device pair. This is so XTest events are correctly propogated via slave
devices up to Master devices and the classes are correctly changed along
the way. We add the XTest slave device pair to the Virtual Core pointer
and provide a simple way of creating the devices.
A XTest Slave Device is identified by the XTstDevicePrivateKey property
being set in the devices devProperties
XI events are still propagated through the matching device, in the hope the
client knows what it is doing.

Previously, three extensions were defined as "trusted" by the extension:
BIG-REQUESTS, XC-MISC, and XPrint. No other extensions were permitted
to be used by untrusted clients.
In commit 8b5d21cc1d this was changed for
some reason. Return to the old, compatible behavior.
The POINTER_SCREEN flag must be set explicitly for XTest core events to avoid
out-of-range events when the lastSlave was an SD with an explicit axis range.
Device events sent through XTest don't need this flag, they are expected to be
in the valuator range of the device anyway.

The masks were originally designed to generically handle event masks for
extensions. Since all that is in-server anyway, it's much better writing
custom event masks for those extensions that need it and not providing a
unified mechanism.
XI2 needs more than the current implementation, which is already too complex
for most other extensions. good riddance.

Requires libselinux 2.0.79 or newer. Without this, libselinux will
check for policy updates on the netlink socket on basically every policy
lookup. Statistically speaking, they never happen, and the check
translates to at least one more syscall on basically every operation.
Instead, take control of the fd from the library, and check it in
WakeupHandler if it polls readable.
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.
X server should never see, translate, or deal with a munged context.
Display managers which show contexts to the user should take care of
translating these to human readable form.
mieqProcessInputEvents() - pop an event off the EQ and pass it to
mieqProcessDeviceEvent() - process the event according to the MD/SD hierarchy.
This way, we can use mieqPDE() from Xtest, xkb, and others to post an event.

The X Server build only needs the macros PANORAMIX_MAJOR_VERSION
and PANORAMIX_MINOR_VERSION from that header.
Addition of extra prototypes to <X11/extensions/panoramiXext.h>
caused a X Server build failure.
Instead of always keeping two copies of the keymap, only generate the
core keymap from the XKB keymap when we really need to, and use the XKB
keymap as the canonical keymap.

All symbols in installed sdk headers should be explicitly tagged
as exported symbols. Otherwise, to ensure it is not a mistake, one
could write it as something like:
extern /* NOEXPORT */ type name ...;
but the proper procedure really should be to use a non sdk header
(or a "noinst_" one).
This patch also removes prototypes to some functions that existed
only temporarily.
A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

All .a libraries were converted to .la, and instead of linking the
Xorg binary with a mix of .a and .la, and adding some libraries more
then once in the command line, etc, now it generates a single libxorg.la
from all the required convenience libraries, and links with a dummy
xorg.c (that should usually be the file with the main function...).
This removes the requirement of some things like libosandcommon and
libinit, that existed to circumvent problems when linking multiple
.a and .la in the final Xorg binary.
The "symbol table" is now generated dynamically, by a shell script,
with an embedded gawk parser that parses cpp output. The new file
sdksyms.sh is generated by hand by analyzing all Makefile.am's and
making it create a sdksyms.c file, that includes all sdk headers that
will add symbols for the Xorg binary. Module headers aren't read, and
a in 2 files it was required to add a "<hash>ifndef XorgLoader" around
declarations shared between the Xorg binary and libextmod. A few
other changes were added to other sdk headers, like preventing
multiple inclusion, or including other headers to satisfy dependencies.
This should be a lot more portable, and better (hopefully properly)
using libtool to generate convenience libraries.
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).
This is done to actually change DIX_CFLAGS, as not all "modules" use
XORG_CFLAGS.
Also export the symbols that are required by other modules after
the change.
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.

There's no reason to not just dispatch this straight into the GC. As a
bonus, if you do so, damage wraps correctly, and thus swcursor works.
The side effect is it's no longer possible to override ShmPutImage with
ShmRegisterFuncs().
Also remove the (broken) damage tracking for same from EXA, since it didn't
work right, and is now superfluous.
