Since destroying a wlr_surface now makes all subsurfaces inert, this
function can no longer fail and return NULL. Document this.

The DRM backend's set_cursor function always return true if the
buffer is NULL. If using a NULL cursor's buffer on startup, the
wlr_output_cursor will be marked as a hardware cursor. If the
cursor later gains a non-NULL buffer and the DRM backend rejects
that buffer, the cursor will remain marked as a hardware cursor,
despite the backend not displaying it as such. As a result, the
cursor will not be displayed at all. Fix this by always resetting
the hardware_cursor field in output_cursor_attempt_hardware().

UNDEFINED when used as source layout means that the contents of
the underlying memory becomes undefined. This isn't what we want
here: we don't want to mutate the imported pixel data.
The Vulkan spec isn't really clear what the proper value should be
here, but after discussing with driver developers [1] it seems like
UNDEFINED isn't the right one. The recommendation is to use GENERAL
instead.

e08d52bb introduced a bug when rotating by 90 or 270 degrees and doing
non-uniform scaling (different scale factor on X and Y axes). The scale
factor was calculated as the ratio between the src box and the rotated
dst box. But scaling is applied after rotation, so the scale factor
should instead be the ratio between rotated src box and dst box.

The old code to render transformed textures with pixman would run
composite over the whole output regardless of the texture size. When
rendering something small this caused a huge performance hit.
Rewrite the transform branch of render_pass_add_texture to:
- Only composite over the rectangle we're drawing to
- Generally try to make things a lot clearer and some comments

We were doing it too early before and the output would disregard a
scheduled frame if called when we were first putting together the output
state

Fix source crop in the pixman render backend. It was being applied by
using a source offset as arguments to pixman_image_composite32(). But
this is wrong because the source crop should get applied before all the
other transforms, not after them (or at least this is how it works in
the other wlroots render backends). Instead, apply the source crop as
yet another matrix transform when we're doing transforms (Or keep it the
same as previously if there's no other transforming going on).

The translations for flipped offsets were set the same as non-flipped
ones which was totally wrong and meant that any textures with
flipped-transforms rendered entirely outside the viewport and were
basically invisible.

Clients may, for example, commit an exclusive zone larger than the
output dimensions. Compositors must handle this gracefully, which likely
requires more work on the compositor side but returning a usable area
with negative width or height in wlr_scene_layer_surface_v1_configure()
is nonsensical.

As of currently, when an xcursor theme depends on itself or another theme
that will eventually depend on it, `xcursor_load_theme` will recurse
infinitely while processing the inherits.
This change introduces a stack-allocated linked list of visited nodes
by name, and skips any already visited nodes in the inherit list.
Side effects:
* Since the linked list is stack-allocated, there is a potential for an
overflow if there is a very long list of dependencies. If this turns out
to be a legitimate concern, the linked list is trivial to convert to
being heap-allocated.
* There is an existing linked list (technically doubly linked list)
implementation in the wayland codebase. As of currently, the xcursor
codebase does not refer to it. Consequently, this change writes a
minimal single linked list implementation to utilize directly.
This changeset is based on the merge request in wayland/wayland!376.
The xcursor code is mostly shared between the two.
This changeset diverges the files slightly due to stylistic differences
between the repositories, but the logic is identical.

In query_modifier_support, the calloc for either or both of render_mods
and texture_mods may fail, in which case both are freed for convenience.
However, if one is non-NULL, vulkan_format_props_finish will try to free
it again.
NULL them to avoid double-free.

When a wlr_gamma_control client calls set_gamma, we allocate a LUT based
on the value returned from wlr_output_get_gamma_size at the time of the
call.
If the output is off and has no CRTC, such as if gamma changes in the
background while a display is disabled for idle reasons,
wlr_output_get_gamma_size returns 0. This leads to a zero-sized table,
which the drm backend interprets as a request to reset gamma tables to
their default.
Store the gamma size when the gamma control was created. Even if the
size changes, this is the size the client was sent and uses to create
the LUTs it sends.

Per comments in util/box.h, the width and height of a wlr_box are
exclusive; that is, for a 100x100 box at (0,0), the point (99,99) is
inside it while the point (100,100) is outside it.
Thus mathematically, there exists no single closest point to the
bottom-right corner of the box while remaining inside it. You can
construct an infinite series approaching the limit, such as {(99,99),
(99.9,99.9), (99.99,99.99)...}, but since the intervals are half-open,
there is no "last" point.
wlr_box_closest_point() must therefore define an arbitrary "closest"
point. For points below and to the right of the box, the current
implementation returns (box.x + width - 1, box.y + height - 1). Let's
continue to do this.
However, the current implementation is non-linear: with the example
100x100 box, it will return an input point of (99.9,99.9) unchanged, but
for an input point (100.1,100.1) the returned point will jump back to
(99.0,99.0).
In practice, this non-linearity results in strange behaviors when
driving the mouse cursor to a screen corner. On a 1920x1080 display for
example, driving the cursor quickly to the bottom-left corner results in
a position of exactly (0,1079). Continuing to slowly nudge the cursor
downward results in the position jumping between (0,1079) and other,
fractional coordinates such as (0,1079.88).
The fractional coordinates expose some client/toolkit-side bugs (which,
to be clear, should be fixed on the client side), but IMHO the wlroots
behavior is also inconsistent and wrong -- when I drive the mouse cursor
into the corner of the screen, it should come to a stop at a fixed
position, not jitter around.

Previously, cases when a viewport source box was updated without attaching
a buffer weren't checked for correctness properly because the state's buffer
would be NULL. Use wlr_surface_state_has_buffer() instead.

The spec for GL_EXT_disjoint_timer_query says
> The GetInteger64vEXT command is required only if OpenGL ES 3.0 or later
> is not supported.
Some GLES 3.2 implementations like the proprietary mali driver on the
rk3566 based OrangePi advertise GL_EXT_disjoint_timer_query but lack
glGetInteger64vEXT. Use glGetInteger64v instead.

Pre-multipled sRGB values need to be un-multiplied before conversion
to linear and then re-multiplied after. Compare shaders/texture.frag.
This fixes an issue in labwc where titlebar corners (rendered as
ARGB textures) did not match the rest of the titlebar (rendered as
a solid wlr_scene_rect).
With the following sequence of events, the cursor FB fields could
end up being all set to NULL while the cursor is enabled:
1. set_cursor is called, conn->cursor_pending_fb is set to a FB
pointer.
2. The output is committed with a buffer. crtc->cursor->queued_fb
is set to the FB pointer, conn->cursor_pending_fb is reset to
NULL. A page-flip event is expected in the future.
3. The output is committed with a modeset before the page-flip
event is triggered. crtc->cursor->queued_fb is reset to NULL.
At this point all of crtc->cursor->current_fb,
crtc->cursor->queued_fb and conn->cursor_pending_fb are NULL which
is a bogus state when the cursor plane is enabled.
To avoid this issue, avoid overwriting crtc->cursor->queued_fb
with a NULL pointer on commit. The cursor logic still isn't great,
but let's keep a rework of that for a separate patch.

A motivating example of such problem - Zoom's popups that open on button presses.
Before this fix the popup would flicker and immediately disappear - because the PID is not yet
available for the verification (as the surface has not been associated yet), wlroots would refuse to
focus the popup and instead focus the previous window. This leads QT to interpret this as a sign to
close the popup.
This change moves the PID aqcuisition to an earlier phase - just where the window is created.
