8c3c6987db backend/wayland: fix touch device not added on startup
We were firing the new_input signal on backend initialization,
before the compositor had the chance to add a listener for it.

Mimick what's done for wl_keyboard: if the backend hasn't been
started, delay wl_touch initialization.

c6032d6b1c backend/libinput: handle high-res scroll events
On newer versions of libinput, the event LIBINPUT_EVENT_POINTER_AXIS
has been deprecated in favour of LIBINPUT_EVENT_POINTER_SCROLL_WHEEL,
LIBINPUT_EVENT_POINTER_SCROLL_FINGER and
LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS.

Where new events are provided by the backend, ignore
LIBINPUT_EVENT_POINTER_AXIS, receive high-resolution scroll events from
libinput and emit the appropiate wlr_pointer signal.

65c436407f pointer: transform low-res to high-res axis events
Currently, the "wlr_event_pointer_axis" event stores low-resolution
values in its "delta_discrete" field. Low-resolution values are always
multiples of one, i.e., 1 for one wheel detent, 2 for two wheel
detents, etc.

In order to simplify internal handling of events, always transform in
the backend from the low-resolution value into the high-resolution
value.

The transformation is performed by multiplying by 120. The 120 magic
number is used by the kernel and it is exposed to clients in the
"WLR_POINTER_AXIS_DISCRETE_STEP" constant.

c84cc660f0 build: check if libinput supports high-res scroll
Starting with Linux Kernel v5.0 two new axes are available for
mice that support high-resolution wheel scrolling: REL_WHEEL_HI_RES and
REL_HWHEEL_HI_RES.

Both axes send data in fractions of 120 where each multiple of 120
amounts to one logical scroll event. Fractions of 120 indicate a wheel
movement less than one detent.

Three new events are now available on libinput:
LIBINPUT_EVENT_POINTER_SCROLL_WHEEL,
LIBINPUT_EVENT_POINTER_SCROLL_FINGER, and
LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS.
These events replace the LIBINPUT_EVENT_POINTER_AXIS event, so new
clients should simply ignore that event.

Also, two new APIs are available to access the high-resolution data:
libinput_event_pointer_get_scroll_value() and
libinput_event_pointer_get_scroll_value_v120().

Add a project argument (LIBINPUT_HAS_SCROLL_VALUE120) to allow
building against old versions of libinput or, where high-resolution
scroll is available, support it.

1d581656c7 backend/drm: set "max bpc" to the max
"max bpc" is a maximum value, the driver is free to choose a
smaller value depending on the bandwidth available.

Some faulty monitors misbehave with higher bpc values. We'll add
a workaround if users get hit by these in practice.

acc6d94db0 backend/drm: make commits without a buffer blocking
The wlr_output API requires compositors to wait for wlr_output.frame
before submitting a new buffer. However, compositors can perform a
commit which doesn't involve a buffer anytime.

If the commit is a modeset, we set DRM_MODE_ATOMIC_ALLOW_MODESET and
block until the commit is done. If it isn't, we currently always
perform a non-blocking commit. This is an issue because a previous
page-flip might still be in flight kernel-side, returning EBUSY.

Fix this by using blocking commits when a buffer isn't submitted by
the compositor.

be86145322 output: turn make/model/serial into char *
This allows the make/model/serial to be NULL when unset, and allows
them to be longer than the hardcoded array length.

This is a breaking change: compositors need to handle the new NULL
case, and we stop setting make/model to useless "headless" or
"wayland" strings.

e59f4d4ffa backend/drm: allow non-linear modifiers for multi-GPU
Prior to [1], if an entry in a DRM format set was different than a
single LINEAR modifier, implicit modifiers were always allowed. This
has changed and now implicit modifiers are only allowed if INVALID
is in the list of modifiers.

So now we can safely enable explicit modifiers for cross-GPU imports,
without risking receiving buffers with an implicit modifier. This
should improve perf a bit on setups where two GPUs from the same vendor
are used.

This fixes the first bullet point from [2].

ec28457508 backend: error out in autocreate without libinput support
The libinput backend is now optional. However, this means that a
user building wlroots without the correct libinput dependencies
will end up with a compositor which doesn't respond to input events.

wlr_backend_autocreate is supposed to return a sensible setup, so in
this case let's just error out and explain what happened. Users can
suppress the check by setting WLR_LIBINPUT_NO_DEVICES=1 (already used
to suppress the zero input device case inside the libinput backend).

Compositors which really want to create a bare DRM backend can easily
create it manually instead of using wlr_backend_autocreate.

9f41627aa1 backend/wayland: add basic linux-dmabuf feedback support
This patch makes it so we bind to zwp_linux_dmabuf_v1 version 4 and
we use it to grab the main device. v4 sends supported formats via a
table so we need to handle this as well.

v4 allows wlroots to remove the requirement for Mesa's internal
wl_drm interface.

bedfec94bb backend/drm: use drmCloseBufferHandle
This has been added in [1] and allows us to close buffer handles
without manually calling drmIoctl.

a15c327718 backend/drm: use drmModeFormatModifierBlobIterNext
This avoids open-coding our own logic. The resulting code is more
readable.

36a2b19485 output: introduce wlr_output_set_name
wlroots picks names for all outputs, but it might be desirable for
compositor to override it.

For instance, Sway will use a headless output as a fallback in
case no outputs are connected. Sway wants to clearly label the
fallback output as such and label "real" headless outputs starting
from HEADLESS-1.

ad28490cf4 build: move wayland-client dep to backend/wayland/
wayland-client isn't really used by wlroots core, so let's move the
dep to where it's needed in the Wayland backend.

812ab2e716 Fix uninitialized variable errors in release mode
When using `meson --buildtype=release`, `-Wextra -Werror` is passed.
This includes `-Werror=maybe-uninitialized`, which complains about
the instances fixed in this commit.

fbaefd90fc backend/drm: poison buffers which cannot be scanned out
Rather than repeatedly trying to import DMA-BUFs which cannot be
scanned out, mark the failed ones with a special "poison" marker.

e163a7cf48 backend/drm: fail on explicit modifier in drmModeAddFB2
drmModeAddFB2 doesn't support explicit modifiers. Only accept INVALID
which indicates an implicit modifier and LINEAR which may indicate
that GBM_BO_USE_LINEAR has been used.

b234edcf58 backend/headless: drop wlr_headless_backend_create_with_renderer
The headless backend no longer needs a parent renderer: it no longer
needs to return it in wlr_backend_impl.get_renderer, nor does it
need to return its DRM FD in wlr_backend_impl.get_drm_fd. Drop this
function altogether since it now behaves exactly like
wlr_headless_backend_create.

f29abe4c77 backend/headless: stop picking a DRM FD
Sometimes the headless backend is used standalone with the Pixman
renderer, sometimes it's used together with another backend which
has already picked a DRM FD. In both of these cases it doesn't make
sense to pick a DRM FD.

Broadly speaking the headless backend doesn't really care which DRM
device is used for the buffers it receives. So it doesn't really
make sense to tie it to a particular DRM device.

Let the backend users (e.g. wlr_renderer_autocreate) open an arbitrary
DRM FD as needed instead.

1d9c1bcea6 input-device: remove wlr_input_device.link
This field's ownership is unclear: it's in wlr_input_device, but
it's not managed by the common code, it's up to each individual
backend to use it and clean it up.

Since this is a backend implementation detail, move it to the
backend-specific structs.
