Simon Ser 348f52b5fc output: remove wlr_output_impl.schedule_frame
This function allowed backends to provide a custom function for frame
scheduling. Before resuming the rendering loop, the DRM and Wayland
backends would wait for vsync.

There isn't a clear benefit of doing this. The only upside is that we
get more stable timings: the delay between two repaints doesn't change too
much and is close to a mutliple of the refresh rate.

However this introduces latency, especially when a client misses a
frame. For instance a fullscreen game missing vblank will need to wait
more than a whole frame before being able to display new content. This
worst case scenario happens as follows:

- Client is still rendering its frame and cannot submit it in time
- Deadline is reached
- Compositor decides to stop the rendering loop since nothing changed on
  screen
- Client finally manages to render its frame, submits it
- Compositor calls wlr_output_schedule_frame
- DRM backend waits for next vblank
- The wlr_output frame event is fired, compositor draws new content on screen
- On the second next vblank, the new content reaches the screen

With this patch, the wlr_output frame event is fired immediately when
the client submits its late frame.

This change also makes it easier to support variable refresh rate, since
VRR is all about being able to present too-late frames earlier.

Guido Günther c9859f187f wlr_output_power_management_v1: Init output_power->link
This makes sure the `wl_list_remove(&output_power->link)` in
`output_power_destroy()` does not crash even when the output_power never
got added to a list. This can e.g. happen in the `mgmt->output ==
output` error path of `output_power_manager_get_output_power`.

Aleksei Bavshin c99d156f0d xdg-shell: fix popups rendered outside of the screen

Michael Weiser 3ff6a5def3 idle-inhibit: Style and naming improvements
Port back style and naming improvements suggested in
https://github.com/swaywm/wlroots/pull/2026 for
keyboard-shortcuts-inhibit. These are all internal to the implementation
and therefore unproblematic.

Also, retrieve the inhibitor resource version from the manager resource
instead of setting it statically.

Michael Weiser 471b873de3 keyboard-shortcuts-inhibit: Implement the protocol
The keyboard shortcuts inhibitor protocol is useful for remote desktop
and virtualization software in order to request all keyboard events to
be passed to it and (almost) none being resonded to by the compositor.
This allows the session at the other end of the remote desktop
connection or inside the virtual machine to be interacted with as usual
(e.g. Alt+Tab to switch windows on the remote system instead of
locally).

Add the wayland protocol to the meson build files.

Copy'n'search'n'replace the very similar idle inhibit protocol
implementation. This already provides all the basic functionality:
- creating and destroying inhibitors upon request by a client,
- destruction in reaction to destruction of surfaces or displays,
- a list of inhibitors to search through for existing ones as well as
- a signal to be sent to the compositor upon registration of a new
  inhibitor.

Beyond that we add the active and inactive events to be sent to the
client and wire those to activate and deactivate functions for the
compositor to call in confirmation of activation of a new inhibitor or
(un-)suspending of an existing inhibitor e.g. in response to a special
key combination entered by the user as suggested by the protocol.

As mandated by the protocol, we check the existance of an inhibitor for
a given surface and seat upon creation and return the error provided by
the protocol for that purpose.

Ilia Bozhinov f416efa918 output-management: add current_configuration_dirty
Previously, if the current configuration contains an output X which is
destroyed, its head is automatically removed. If the compositor submits
the new configuration after X was removed, the current output
configuration is incorrectly detected to be the same as the previous
one, and no done event is sent. To prevent this, we can just keep track
of whether the current configuration is dirty, i.e whether we have sent
a done event for it.

Manuel Stoeckl f22a5d1704 Fix output rotation direction
The Wayland protocol specifies output transform rotations to be
counterclockwise and applied to the surface. Previously, wlroots
copied Weston and incorrectly made rotations act clockwise on
surfaces. This commit fixes that.

This change will break compositors which expect transform rotations
to be clockwise, and the rare applications that make use of surface
transforms.

Scott Anderson cff1c2f740 meson: Various improvements
Bumps minimum version to 0.51.0

- Remove all intermediate static libraries.
  They serve no purpose and are just add a bunch of boilerplate for
  managing dependencies and options. It's now managed as a list of
  files which are compiled into libwlroots directly.

- Use install_subdir instead of installing headers individually.
  I've changed my mind since I did that. Listing them out is annoying as
  hell, and it's easy to forget to do it.

- Add not_found_message for all of our optional dependencies that have a
  meson option. It gives some hints about what option to pass and what
  the optional dependency is for.

- Move all backend subdirectories into their own meson.build. This
keeps some of the backend-specific build logic (especially rdp and
session) more neatly separated off.

- Don't overlink example clients with code they're not using.
  This was done by merging the protocol dictionaries and setting some
  variables containing the code and client header file.
  Example clients now explicitly mention what extension protocols they
  want to link to.

- Split compositor example logic from client example logic.

- Minor formatting changes

Some globals are static and it doesn't make sense to destroy them before

For these globals, we can simplify the code by removing the destructor
and stop keeping track of wl_resources (these will be destroyed with the
wl_display by libwayland).

An alternative would be to move commit_seq in wlr_output_state. This
would allow to have a pending and a current commit_seq.
wlr_output_send_present could take the pending commit_seq when called
with a NULL event.

Brian Ashworth f2d3b1000f Introduce wlr_keyboard_group
A wlr_keyboard_group allows for multiple keyboard devices to be
combined into one logical keyboard. Each keyboard device can only be
added to one keyboard group. This helps with the situation where one
physical keyboard is exposed as multiple keyboard devices. It is up to
the compositors on how they group keyboards together, if at all.

Since a wlr_keyboard_group is one logical keyboard, the keys are a set.
This means that if a key is pressed on multiple keyboard devices, the
key event will only be emitted once, but the internal state will count
the number of devices that the key is pressed on. Likewise, the key
release will not be emitted until the key is released from all devices.
If the compositor wants access to which keys are pressed and released
on each keyboard device, the events for those devices can be listened
to, as they currently are, in addition to the group keyboard's events.

Also, all keyboard devices in the group must share the same keymap. If
the keymap's differ, the keyboard device will not be able to be added
to the group. Once in the group, if the keymap or effective layout for
one keyboard device changes, it will be synced to all keyboard devices
in the group. The repeat info and keyboard modifiers are also synced

Simon Ser ee5f98ad49 output: atomic mode, enabled, scale and transform
This commit makes more output properties (mode, enabled, scale and transform)
atomic. This means that they are double-buffered and only applied on commit.

Compositors now need to call wlr_output_commit after setting any of those
properties.

Internally, backends still apply properties sequentially. The behaviour should
be exactly the same as before. Future commits will update some backends to take
advantage of the atomic interface. Some backends are non-atomic by design, e.g.
the X11 backend or the legacy DRM backend.

Jason Francis 724b5e1b8d screencopy: send failed after output disconnect
This prevents screencopy applications from hanging because a failed

the call to buffer().

Jason Francis ce3e413e83 screencopy: fix segfault on disabled output
Disconnecting or disabling an output between capture_output() and
ready() could cause either a NULL dereference or an incorrect
attach_render_locks count.

Simon Ser ca45f4490c Remove all wayland-server.h includes
The documentation for wayland-server.h says:

> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.

Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.

Simon Ser 76ef089f52 output: drop wlr_output_mode.flags
AFAIK this was always set to zero. Instead, compute wl_output mode flags on the
fly.

Technically this is a breaking change, but I don't think anybody uses this
field.

Guido Günther df3f0ffbb0 wlr_seat_touch: Don't destroy touch point with surface
When the surface is destroyed clear it's reference but wait for the up
event to destroy the touch point via wlr_seat_touch_notify_up().

If the surface is destroyed before the up event we end up with
incomplete sequences sent to the client like

[915821.276] wl_touch@3.down(146, 2475027, wl_surface@38, 0, 236.000000, 515.000000)
[915821.608] wl_touch@3.frame()
[915821.637] wl_touch@3.motion(2475027, 0, 236.000000, 515.000000)
[915821.779] wl_touch@3.frame()

so there's never an up event. While it should be something like

[2461229.051] wl_touch@3.down(81, 3236959, wl_surface@34, 0, 218.000000, 478.000000)
[2461229.435] wl_touch@3.frame()
[2461229.484] wl_touch@3.motion(3236959, 0, 218.000000, 478.000000)
[2461229.636] wl_touch@3.frame()
[2461277.520] wl_touch@3.up(82, 3237007, 0)
[2461277.681] wl_touch@3.frame()

this confuses toolkits intepreting the next down event incorrectly. So
don't destroy the touch point too early.

Manuel Stoeckl edb30a6828 Implement serial validation for selection requests
This change tracks, for each wlr_seat_client, the most recent serial
numbers which were sent to the client. When the client makes a
selection request, wlroots now verifies that the serial number
associated with the selection request was actually provided to that
specific client. This ensures that the client that was most
recently interacted with always has priority for its copy selection
requests, and that no other clients can incorrectly use a larger serial
value and "steal" the role of having the copy selection.

Also, the code used to determine when a given selection is superseded
by a newer request uses < instead of <= to allow clients to make
multiple selection requests with the same serial number and have the
last one hold.

To limit memory use, a ring buffer is used to store runs of sequential
serial numbers, and all serial numbers earlier than the start of the
ring buffer are assumed to be valid. Faking very old serials is
unlikely to be disruptive.

Assuming all clients are correctly written, the only additional
constraint which this patch should impose is that serial numbers
are now bound to seats: clients may not receive a serial number
from an input event on one seat and then use that to request
copy-selection on another seat.

Simon Ser ce3f4c3fe1 output: remove wlr_output_impl.transform
The backend doesn't need to handle transform changes, since everything is done
in software. In fact, all of the implementations were all identical and just
set the transform.

We could add support for hardware transforms, but:

- This would require a different field (something like hardware_transform)
- Not all combinations are possible because there often are hardware
  limitations
- The Wayland protocol isn't ready for this (in particular xdg-output, see [1])

This belongs to a different patch series anyway.

Simon Ser 33127c545b output: reset the pending state on failed commit
It can be surprising for callers to stash pending changes, commit, get a
failure, then set some other pending changes, commit again, and get another
failure because of the previously-pending changes.

Instead, make commit reset the pending state on failure.

Ashkan Kiani 06a13203dd Use a set to track pointer button state.
In addition to `button_count`, we keep track of the current buttons
pressed just as in `wlr_keyboard`.

Add `set_add` and `set_remove` to assist with this. These functions can
only be used with values greater than 0 (such as the button/key masks
for keyboards and pointers).
