87d7e3e352 dix: only show the cursor if a window defines one (#58398)
e02f864fdf "Suppress cursor display until the first XDefineCursor() request"
disabled cursor display a priori unless -retro is given.

On a plain server, caling XFixesHideCursor() and XFixesShowCursor() would
show the default root cursor, despite no client actually defining a cursor.

Change the logic, disable CursorVisible by default and only enable it from
the window's CWCursor logic. If no window ever defines a cursor, said cursor
stays invisible.

310ac85080 dix: Save touchpoint last coordinates before transform. #49347
DDXTouchPointInfoRec.valuators used to store axis values after transform.
This resulted in Coordinate Transformation Matrix
being applied multiple times to the last coordinates,
in the case when only pressure changes in the last touch event.

Changed DDXTouchPointInfoRec.valuators to store values before transform.

df12c4daa7 input: Record grab pointer in TouchListener
This places a pointer to the grab related to a TouchListener directly
in the TouchListener structure rather than hoping to find the grab
later on using the resource ID.

Passive grabs have resource ID in the resource DB so they can be
removed when a client exits, and those resource IDs get copied when
activated, but implicit grabs are constructed on-the-fly and have no
resource DB entry.

73bd33b4d4 xkb: fill in keycode and event type for slow keys enablement
eventType is set for the type that triggered a XkbControlsNotify event.
Technically, SlowKeys is triggered by a timer which doesn't have a matching
core event type. So we used to use 0 here.

Practically, the timer is triggered by a key press + hold and cancelled when
the key is released before the timeout expires. So we might as well set
KeyPress (keycode) in the ControlsNotify to give clients a chance to differ
between timer-triggered SlowKeys and client-triggered ones.

This is a chance in behaviour, though I suspect with little impact.

b8ab93dfbc list: Use offsetof() and typeof() to determine member offsets within a structure
Some compilers have difficulty with the previous implementation which
relies on undefined behavior according to the C standard.  Using
offsetof() from <stddef.h> (which most likely just uses
__builtin_offsetof on modern compilers) allows us to accomplish this
without ambiguity.

This fix also requires support for typeof().  If your compiler does not
support typeof(), then the old implementation will be used.  If you see
failures in test/list, please try a more modern compiler.

v2: Added fallback if typeof() is not present.

aad428b8e2 glx: drop GLX_LIBS from X server and workaround sdksyms.
We've had reports of two copies of the GLX bits, one in the server
and one in libglx.so causing problems, I didn't understand why the
X server needed a copy so drop it, however then we have to fix a missing
GlxExtensionInit that comes from sdksyms, so work around it by moving
that one declaration into a header that sdksyms doesn't scan.

Thanks to Jon Turney for debugging the actual problem.
(copyright header from extinit.h that seems most appropriate put on top).

f2da2c1204 randr: add initial scanout pixmap support (v3)
When randr notices a crtc configuration request for a slave device,
it checks if the slave allocated pixmap exists and is suitable,
if not it allocates a new shared pixmap from the master, shares
it to the slave, and starts the master tracking damage to it,
to keep it updated from the current front pixmap.

If the resize means the crtc is no longer used it will destroy
the slave pixmap.

This adds the concept of a scanout_pixmap to the randr_crtc object,
and also adds a master pixmap pointer to the pixmap object, along
with defining some pixmap helper functions for getting pixmap box/regions.

v2: split out pixmap sharing to a separate function.

9d17981829 dix: introduce gpu screens. (v5)
This patch introduces gpu screens into screenInfo. It adds interfaces
for adding and removing gpu screens, along with adding private fixup,
block handler support, and scratch pixmap init.

GPU screens have a myNum that is offset by GPU_SCREEN_OFFSET (256),
this is used for logging etc.

RemoveGPUScreen isn't used until "xfree86: add platform bus hotplug support".

v2: no glyph pictures for GPU screens for now.
v3: introduce MAXGPUSCREENS, fix return value check
v4: fixup myNum when renumbering screens (ajax)
v5: drop cursor privates for now.

cf66471353 xfree86: use udev to provide device enumeration for kms devices (v10)
On Linux in order for future hotplug work, we are required to interface
to udev to detect device creation/removal. In order to try and get
some earlier testing on this, this patch adds the ability to use
udev for device enumeration on Linux.

At startup the list of drm/kms devices is probed and this info is
used to load drivers.

A new driver probing method is introduced that passes the udev
device info to the driver for probing.

The probing integrates with the pci probing code and will fallback
to the pci probe and old school probe functions in turn.

The flags parameter to the probe function will be used later
to provide hotplug and gpu screen flags for the driver to behave
in a different way.

This patch changes the driver ABI, all drivers should at least
be set with a NULL udev probe function after this commit.

v2: rename to platform bus, now with 100% less udev specific,

this version passes config_odev_attribs around which are an array
of id/string pairs, then the udev code can attach the set of attribs
it understands, the OS specific code can attach its attrib, and then
the core/drivers can lookup the required attribs.

also add MATCH_PCI_DEVICES macro.

This version is mainly to address concerns raised by ajax.

v3: Address comments from Peter.
fix whitespace that snuck in.
rework to use a linked list with some core functions that
xf86 wraps.

v4: add free list, fix struct whitespace.
ajax this address most of your issues?

v5: drop probe ifdef, fix logic issue

v6: some overhaul after more testing.

Implement primaryBus for platform devices.
document hotplug.h dev attribs - drop sysname attrib
fix build with udev kms disabled
make probing work like the PCI probe code,
   match against bus id if one exists, or primary device.

RFC: add new bus id support "PLAT:syspath". we probably
want to match on this a bit different, or use a different
property maybe. I was mainly wanting this for use with
specifying usb devices in xorg.conf directly, but PLAT:path
could also work I suppose.

v6.1: add missing noop platform function

v7: fix two interactions with pci probing and slot claiming, prevents
pci and platform trying to load two drivers for same slot.

v8: test with zaphod mode on -ati driver, fixup resulting issue
clean up common probe code into another function, change busid
matching to allow dropping end of strings.

v9: fix platform probing logic so it actually works.
v9.1: fix pdev init to NULL properly.

v10: address most of Keith's concerns.
