Let's simplify this code by asserting, and letting it explode naturally
(return Inf, possibly SIGFPE depending on external factors) if compiled
NDEBUG, instead of a contained explosion (safely returning 0).
If this actually happens it's Really Bad, so we'd like to catch is ASAP,

If the view transform is dirty it might be incorrect. Also, we normally
set up the view transform matrix properly regardless of whether the
transform is enabled or not - but if we've never run
weston_view_update_transform() it will be all zeros.
This is a step towards removing view->transform.enabled checks and just
using the transform matrix in all cases.

This adds basic VNC protocol support using the Neat VNC library
(https://github.com/any1/neatvnc). Neat VNC depends on the AML main
loop library. The backend makes use of AML's integrated epoll backend
and connects AML via file descriptor with the Wayland event loop.
This implementation does not support authentication and hardcodes the
pixel format currently.

Previously renderers were not told when the output (framebuffer they
need to draw) size changed. Renderers just pulled that information out
from weston_output::current_mode when they happened to need it. This
makes some things awkward, like resizing the shadow or intermediate
buffers. In fact, Pixman-renderer does not even support resizing its
shadow buffer, nor does GL-renderer. DRM-backend has to destroy and
re-create the renderer output state anyway, but rdp, x11 and wayland
backends would be natural users of resizing API.
This commit adds an API for resizing with empty implementations. Actual
implementations will be added in following patches for each renderer
while moving parts of resizing code from backends into the renderers.
No-op renderer needs no implementation.
Only wayland-backend has actual resizing code already, and that is made
to call the new API. Unfortunately, Pixman and GL renderers differ: one
does not blit them while the other does. In order to assert the
functionality of each renderer to keep the API consistent,
wayland-backend needs to lie to pixman-renderer. That's not new, it
already does so in wayland_output_get_shm_buffer() where the 'pm_image'
addresses only the interior area instead of the whole buffer.

New function that transforms a pixman_box32_t rectangle by a matrix.
Since pixman rectangles are represented by 2 corners, non-90 degree
rotations can't be properly represented. This function gives the
axis aligned rectangle that encloses the rotated rectangle.
We use this for weston_matrix_transform_region(), simplifying it and
allowing it to work for non 90 degree rotations.

Surface views that are not assigned to a layer are not going to be
rendered, and thus should not participate in determining the outputs the
surface is on.
There are other view properties that may determine if the view should be
considered in output_mask calculations, e.g., is_mapped, but checking
for this currently breaks tests. Such additional checks are left for
future fixes or reworkings of the view infrastructure.

When an atomic commit fails then the output will be stuck in
REPAINT_AWAITING_COMPLETION state. It is waiting for a vblank event that was
never scheduled.
If the error is EBUSY then it can be expected to be a transient error. So
propagate the error and schedule a new repaint in the core compositor.
This is necessary because there are some circumstances when the commit can fail
unexpectedly:
- With 'state_invalid == true' one commit will disable all planes. If another
commit for a different output is triggered immediately afterwards, then this
commit can temporarily fail with EBUSY because it tries to use the same
planes.
- At least with i915, if one commit enables an output then a second commit for a
different output immediately afterwards can temporarily fail with EBUSY. This
is probably caused by some hardware interdependency.

The paint_node_z_order_list contains all views, not just the ones visible on the
current output. So all views are moved to the primary plane when one output
does not support planes.
This will be relevant with multiple backends: When an output without plane
support is rendered then the views of all other outputs are removed from
the current planes and the corresponding outputs will be repainted
unnecessarily.
So only reset the plane if the view is actually on the current output.

This patch acts as bandaid in the core compositor to avoid the renderer
doing a flush after the buffer has been released. Flushing after release
can happen due to problems in the internal damage tracking, is violating
the protocol, and causes visible glitches.
A more proper fix would be to handle compositor side damage correctly.

Currently the idle_repaint_source is removed when the output is destroyed.
This covers the most common case: When a monitor is unplugged then the
corresponding DRM output is destroyed and not just disabled.
However, outputs can be explicitly disabled by the shell. In this case the
output is not removed and idle_repaint() may be called for a removed
output.
Remove the idle_repaint_source in weston_compositor_remove_output() to fix
this. And reset the variable to ensure that the source can be created
again.
Removing the source in weston_output_release() is now no longer necessary
since it calls weston_compositor_remove_output().

Currently, the opaque is discarded for all transformations other than a simple
translation, because correctly transforming the opaque area is not possible in
general.
However, there is one simple case that is probably the most common one: A fully
opaque surface that is translated and scaled. In this case the opaque area is
simply the new bounding box. So set the transformed opaque area accordingly.
Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
If surface->is_opaque is set then we can assume that the whole surface is
opaque. In the trivial case (no transformation or translation only) this means
that transform.boundingbox is exactly the view area and is fully opaque. So it
can be used for transform.opaque.
This is important because damage calculation uses transform.opaque. Without
this, anything underneath a surface without an explicit opaque region but a
pixel format without alpha channel is drawn unnecessarily.

Output color profile may be changed in flight. Output basic color
characteristics and EOTF mode cannot yet be changed in flight, but it is
reasonable to assume they could in the future. Therefore the color
outcome data may change in flight as well, which is the basis for HDR
metadata, which needs to be updated as well.
Track the changes to color outcome data with a serial number.
DRM-backend checks the serial number to see if it needs to re-create the
HDR metadata blob. This allows the changes to propagate all the way to
KMS.

This adds color_chracteristics field in weston_output. This field is
intended to be set by compositor frontends and read by color managers.
Color managers can use this information when choosing the output color
space and dynamic range, particularly when no ICC profile has been set.
This is most useful for HDR outputs, where the HDR static metadata for
PQ mode or the display luminance parameters for HLG mode can be based on
color_characteristics.
The fields of weston_color_characteristics mirror the information
available in EDID. However, using EDID information as-is has several
caveats, so the decision to use EDID for this is left for the frontend
and ultimately to the end user.
There are no defined ranges or validity checks for this data. The color
manager will have to validate the values against whatever it is using
them for.
