Fixes this build error on arch linux:
../Xi/exevents.c:1394:26: error: array subscript ‘InternalEvent {aka union _InternalEvent}[0]’ is partly outside array bounds of ‘DeviceEvent[1]’ {aka ‘struct _DeviceEvent[1]’} [-Werror=array-bounds=]
1394 | evtype = GetXI2Type(ev->any.type);
| ^~~~~~~~~~~~~~~~~~~~~~~~
../Xi/exevents.c: In function ‘DeliverEmulatedMotionEvent’:
../Xi/exevents.c:1571:17: note: object ‘motion’ of size 432
1571 | DeviceEvent motion;
|
which happens because of change in build options compared to master and gcc 15.1 in arch. I think this warning (and error) is a bug in gcc.
gcc 15.1 doesn't like when struct DeviceEvent is cast to union InternalEvent.
InternalEvent has a union any type and DeviceEvent type and these have to have a matching structure (for the header part).
When the InternalEvent is used in RetrieveTouchDeliveryData function it access the any field, which accessed the data defined previously in the device_event fields.
This change matches how its done in touch.c TouchEmitTouchEnd for example and it's "more correct",
since we are no longer casting from a smaller struct (DeviceEvent) to a larger struct (InternalEvent) when calling RetrieveTouchDeliveryData.

* xled change tested with `xset led named "Scroll Lock"`
* modesetting change tested with `xrandr --output DP-1 --gamma 0.5:0.5:0.5`.
Without this fix that command does nothing
* xvmc change tested with `mpv --vo=xv video.mp4`
Of the currently reported issues this fixes#104

The `buflength` variable doesn't exist anymore, it's `rlength`.
And even if the reply struct might have the same size as XGenericReply,
it's cleaner to let the compiler compute it explicitly, just in case.

It seems xf86bigfont hasn't been compile-tested for long time,
some includes were missing.
Note that fontstruct.h needs to come before libxfont2.h, because X11
headers tend to be not self-consistent :(

This fixes a regression in 5499a2999 (xkb: let SendDeviceLedFBs() fill buffer instead of writing directly, 2024-07-16).
We need to write the whole buffer, and the updated length has to take
into consideration that `sz` now contains `led_len` so we need to
subtract that or properly calculate the remaining size.

As long as the wfb module is still a separate shared object, this

Yet another temporary re-export for Nvidia's proprietary driver.
This symbol really shouldn't be used at all by drivers.

Selection names (as seen by the client) are internally prefixed with the
namespace ID, so each client can only access those within it's namespace.
If a client within namespace "foo" want's to operate on "PRIMARY",
it actually will be doing so on "<foo>PRIMARY", w/o ever noticing it.
Events will sent back to the client still pointing to "PRIMARY".
