When an X11 client issues a ConfinePointer wit ha hidden cursor,
Xwayland may translate that as a pointer lock.
However, if the pointer is located on another window at the time,
the request may be ignored, even if the pointer later enters the window.
To avoid that issue, check again if locking the pointer with a hidden
cursor is needed when pointer enters a surface.

When an X11 client has an active grab on the pointer, all events are
reported relative to the window with the grab.
For Xwayland, if an X11 client has a grab with a pointer confinement
active, while pointer focus is on another window, motion events should
not be reported to the client with the grab, because that sets the X11
client appart, the events would be reported when the pointer is on any
X11 window but not on Wayland native surfaces.
Therefore, if the pointer is confined on a window and that window
differs from the actual pointer focus window, just pretend we lost
pointer focus to another window.

If a client issues a grab on the pointer while the cursor is on another
X11 window, and then hides the cursor, we may end up locking the pointer
onto that other window.
Then a button click might end up moving the focus away from the window
which issued the grab, leaving the whole setup in a mixed up state.
Typically, if the pointer is on another X11 window, we should not try to
lock the pointer, so that it can be moved back to the window which
actually issues the grab (and hence the pointer confinement). Typically,
this is the same as an X11 client issuing a pointer grab while the
cursor is on another Wayland native window.

Mutter recently added headless tests, and when running those tests the
Wayland compositor runs for a very short time.
Xwayland is spawned by the Wayland compositor and upon startup will
query the various Wayland protocol supported by the compositor.
To do so, it will do a roundtrip to the Wayland server waiting for
events it expects.
If the Wayland compositor terminates before Xwayland has got the replies
it expects, it will loop indefinitely calling `wl_display_roundtrip()`
continuously.
To avoid that issue, add a new `xwl_screen_roundtrip()` that checks for
the returned value from `wl_display_roundtrip()` and fails if it is
negative.

All helper client code now uses xcb, so calling XSetAuthorization() is
no longer needed.
This is the last reference to libX11 from helper clients, so linking
with x11-xcb and libX11 is no longer required.
Also drop (unneeded?) linking with libXau.
Also drop installing these prerequistes on AppvVeyor.
Also move prototypes for functions in winauth.c from win.h into a new
header, winauth.h, and include that where needed.
Convert clipboard integration code from libX11 to xcb
This drops support for COMPOUND_TEXT. Presumably some ancient
(pre-2000) clients exist which support that, but not UTF8_STRING, but we
don't have an example to test with. (Given the nature of the thing, the
users of those clients probably work in CJK languages)
Supporting COMPOUND_TEXT would also involve writing (or extracting from
Xlib) support for the ISO 2022 encoding.
v2:
Fix the length of text property set by a SelectionRequest
The length of the text property is not neccessarily the same as the
length of the clipboard text before it is d2u converted (specifically,
if that contains any '\r\n' sequences, it will be shorter as they are
now just '\n')
Always use CF_UNICODETEXT clipboard format. Windows will automatically
down-convert to CF_TEXT for clients which request that.
This is subtly different in one way: if CF_TEXT is requested, we now
post CF_UNICODETEXT and it is converted to CF_TEXT *in the locale of the
requesting process*. Previously, we would convert to CF_TEXT *in our
locale* and post that.
It looks like the code in the !X_HAVE_UTF8_STRING case didn't actually
work correctly, but fortunately that has never been true...
The original Win32 clipboard API is widely regarded as terrible, since
it relies on clients co-operatively managing the clipboard viewer chain,
and a single buggy client can break it for all other clients.
The last Windows version only supporting that API was Windows XP (5.1),
EOLed in 2014.
(This requires MinGW-w64 w32api 6.0.0 or later for
Add/RemoveClipboardListener correctly exported by the x86_64 user32
implib)
Also, relax the timeout mechanism so it allows 1 second between events,
rather than 1 second for the entire transfer, as transfers of large
pastes can take more than 1 second.
Also, prefer UTF8_STRING encoding to COMPOUND_TEXT encoding
This option was implemented before the drivers were split in ≈2006,
and e.g. XWin still supports it.

For window-manager managed windows, xwl_realize_window is only called for
the window-manager's decoration window and not for the actual client window
on which we should set the _XWAYLAND_RANDR_EMU_MONITOR_RECTS prop.
Usualy this is not a problem since we walk all client windows to update
the property when the resolution is changed through a randr call.
But for apps which first do the randr change and only then create their
window this does not work, and our xwl_output_set_window_randr_emu_props
call in xwl_realize_window is a no-op as that is only called for the wm
decoration window and not for the actual client's window.
This commit fixes this by making ensure_surface_for_window() call
xwl_output_set_window_randr_emu_props on the first and only child of
window-manager managed windows.
Note this also removes the non-functional xwl_output_set_window_randr_emu_props
call from xwl_realize_window, which was intended to do this, but does not
work.
This fixes apps using the ogre3d library always running at the

Some clients, which use vidmode to change the resolution when going fullscreen,
create an override-redirect window and never trigger the screen->ResizeWindow
callback we rely on to do the xwl_window_check_resolution_change_emulation().
This causes us to not apply a viewport to them, causing the fullscreen window
to not fill the entire monitor.
This commit adds a call to xwl_window_check_resolution_change_emulation()

ensure_surface_for_window() exits early without creating an xwl_window
for new windows which will not be backed by a wayland surface and which
thus will not have an xwl_window.

This means we need to do something similar in xwl_output_set_emulated_mode()

and we this should remove any emulated modes set by the client.
All callers of xwl_output_set_emulated_mode always pass a mode pointer

duplicate this code, instead we can simply check that the passed in mode

When fullscreening a X11 window, mutter moves its window-decoration Window
wrapping the top-level Window to the monitor's origin coordinates (e.g. 0x0)
last. This updates the top-level's drawable coordinates, but as the
actual MoveWindow is called on the wrapper Window and not on the toplevel

On the particular machine I was trying to set up an UDL device,
I found the following structure was being used to match
the device to a platform device while I was debugging the issue:
xf86_platform_devices[0] == Intel, /dev/dri/card1, primary platform device
xf86_platform_devices[1] == UDL, /dev/dri/card0
devList[0] == "Intel0", ZaphodHeads: DP1
devList[1] == "Intel1", ZaphodHeads: VGA1
devList[2] == "UDL"
devList[3] == "Intel2", ZaphodHeads: HDMI1 (intended GPU device to UDL)
When xf86platformProbeDev() matched the UDL device, the BusID
check failed in both cases of:
* BusID "usb:0:1.2:1.0" was specified
* Option "kmsdev" "/dev/dri/card0" was specified
As a result, xf86platformProbeDev() went on to call probeSingleDevice()
with xf86_platform_devices[0] and devList[2], resulting in the
UDL device being set up as a GPU device assigned to the first screen
instead of as a framebuffer on the third screen as the configuration
specified.
Checking Option "kmsdev" in code code may be a layering violation.
But the modesetting driver is actually part of the Xorg sources
instead of being an external driver, so he "kmsdev" path knowledge
may be used here.

Commit cb1b1e184 modified msSharePixmapBacking() to derive modesettingPtr from
the 'screen' argument. Unfortunately, the name of the argument is misleading --
the screen is the slave screen. If the master is modesetting,
and the slave is not modesetting, it will segfault.
To fix the problem, this change derives modesettingPtr from
ppix->drawable.pScreen. This method is already used when calling
ms->glamor.shareable_fd_from_pixmap() later in the function.
To avoid future issues, this change also renames the 'screen' argument to
'slave'.

Make sure we recycle the buffers on `SetWindowPixmap` to ensure that
the buffers will be recycled whenever the pixmap size is changed.

Add a mechanism to create, recycle and destroy window buffers when
needed.
Typically, this adds a new `xwl_window_buffer` structure which
represents a buffer for a given Xwayland window.
Each Xwayland window has two different pools of buffers:
- The available buffers pool:
Those are buffers which where created previously and that have either
not been submitted to the compositor or submitted and released.
- The unavailable buffers pool:
Those are typically the buffers which are being used by the
compositor, awaiting a release.
Initially, an Xwayland window starts with both pools empty. As soon as a
new buffer is needed, it's either created (if there is none available)
or picked from the pool of available buffers.
Once submitted to the compositor, the buffer is moved to the pool of
unavailable buffers. When the corresponding `wl_buffer` is released by
the compositor, it is moved back to pool of available buffers again to
be reused when needed.
To avoid keeping too many buffers around doing nothing, a garbage
collection of older, unused buffers also takes care of disposing the
buffers being unused for some time.

The API `wl_buffer_add_listener` is misleading in the sense that there
can be only one `wl_buffer` release callback, and trying to add a new
listener when once is already in place will lead to a protocol error.
The Xwayland EGL backends may need to set up their own `wl_buffer`
release listener, meaning that there is no way to our own `wl_buffer`
release callback.
To avoid the problem, add our own callback API to be notified when the
`wl_buffer` associated with an `xwl_pixmap` is released, triggered from
the different `xwl_pixmap` implementations.
Also update the Present code to use the new buffer release callback API.

Currently, when a X11 client (usually the X11 window manager from a
Wayland compositor) changes the value of the X11 property
`_XWAYLAND_ALLOW_COMMITS` from `false` to `true`, all pending frame
callbacks on the window are discarded so that the commit occurs
immediately.
Weston uses that mechanism to prevent the content of the window from
showing before it's ready when mapping the window initially, but
discarding the pending frame callbacks has no effect on the initial
mapping of the X11 window since at that point there cannot be any frame
callback on a surface which hasn't been committed yet anyway.
However, discarding pending frame callbacks can be problematic if we
were to use the same `_XWAYLAND_ALLOW_COMMITS` mechanism to prevent
damages to be posted before the X11 toplevel is updated completely
(including the window decorations from the X11 window manager).
Remove the portion of code discarding the pending frame callback,
Xwayland should always wait for a pending frame callback if there's one
before posting new damages.

During startup, the xfree86 DDX's InitOutput() calls PreInit for
protocol screens first, and then GPU screens. On teardown, dix_main()
calls CloseScreen in the reverse order: GPU screens first starting with
the last one and then working backwards, and then protocol screens also
in reverse order.
InitOutput() calls ScreenInit in the wrong order: for GPU screens first and then
for protocol screens. This causes a problem for drivers that have global state
that is tied to the first screen that calls ScreenInit.
Fix this by simply re-ordering the for loops to call PreInit for
protocol screens first and then for GPU screens second.
ms_present_get_crtc() returns an RRCrtcPtr, but derives it from a xf86CrtcPtr
found via ms_dri2_crtc_covering_drawable()=>ms_covering_crtc(). As a result, it
depends on all associated DIX ScreenRecs having an xf86CrtcConfigPtr DDX
private.
Some DIX ScreenRecs don't have an xf86CrtcConfigPtr DDX private, but do have an
rrScrPrivPtr DDX private. Given that we can derive all of the information we
need from RandR, we can support these screens by avoiding the use of xf86Crtc.
This change implements an RandR-based path for ms_present_get_crtc(), allowing
drawables to successfully fall back to syncing to the primary output, even if
the slave doesn't have an xf86CrtcConfigPtr DDX private.
Without this change, if a slave doesn't have an xf86CrtcConfigPtr DDX private,
drawables will fall back to 1 FPS if they overlap an output on that slave.

before dereferencing it. This will still mean that ms_covering_crtc() can't fall

1 FPS default instead), but it won't segfault.

ms_covering_crtc() uses RRFirstOutput() to determine a primary output to fall
back to if a drawable is overlapping a slave output.
If the primary output is a slave output, RRFirstOutput() will return a slave
output even if passed a master ScreenPtr. ms_covering_crtc() dereferences the
output's devPrivate, which is invalid for non-modesetting outputs, and can
crash.
Changing RRFirstOutput() could have unintended side effects for other callers,
so this change replaces the call to RRFirstOutput() with ms_first_output().
ms_first_output() ignores the primary output if it doesn't match the given
ScreenPtr, choosing the first connected output instead.
