This allows for setting a buffer offset without having to make it part
of the wl_surface.attach request. This is useful for e.g. setting a DND
surface icon hotspot offset when using Vulkan; or doing the same with
EGL without having to use wl_egl_window_resize().

In the future we'll have multiple output support, which makes storing
the peer list on an output rather tricky.

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.

Since b38b735e20, 'backend-drm: Remove Pixman conditional
for keep_buffer' the Pixman renderer keeps its own reference to buffers
when attached to surfaces, rather than flipping keep_buffer variable for
the surface. Problem is that when switching from the Pixman render to
the GL would not work and could result in a crash upon first repaint.

When an output is destroyed then the output state is freed immediately. In this
case, the plane state is only partially destroyed because it is the currently
active state. This includes the buffer reference.
Without the output, the plane will not be updated any more until it is used by a
different output (if possible) or the output returns and the plane is used
again.
As a result, the buffer reference is kept for a long time. This will cause some
applications to stall because weston now keeps two buffers (the one here and
another one for a different output where the application is now displayed).
To avoid this, do a synchronous commit that disables the output. The output
needs to be disabled anyways and this way the current state contains no
buffers that would remain.
`device->state_invalid = true` in drm_output_detach_crtc() is no longer
needed, because drm_output_detach_crtc() is called only when initialization
failed and the crtc was not yet used or in drm_output_deinit() when the
crtc was already disabled with the new synchronous commit.

noop-renderer needs to actually access the buffer content, to ensure
that the bad-buffer test works. This was previously done using a
volatile variable, but clang rightly pointed out that the variable
access had no effect (since the volatile stack variable was never read
from, and the source is not volatile), so 9b0b5b57dd changed it to be
explicitly marked it as unused to suppress the compiler warning.
Unfortunately suppressing the warning still leaves the compiler free to
optimise out the access.
Replace the variable decorations with actually using the result of the
read, so we can be really sure that it's never going to be optimised
away.

Our positioning of override redirect windows falls apart when an
app is on the fullscreen layer, because we end up putting its
menus and tooltips beneath it. This patch raises the special
override redirect layer to be just below things like on-screen
keyboards (and, unfortunately, above things like panels).
There is no perfect way to deal with this problem, especially
for content like tooltips that don't come with transience hints.
In some cases override redirect menus could be better placed by
using the parenting/transience information provided with them
at map time, and we should probably do that at some point, but
that would still leave us with tooltips below full screen
applications, and the need for this layer change.

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().
Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
weston_compositor_reflow_outputs() assumes that all output are positioned from
left to right with no gaps in the same order in which they where created.
If the shell moves an output with weston_output_move() then this assumption is
no longer true. So stop reflowing the outputs in the case. The shell is now
responsible for positioning all outputs as needed.

By moving the application of view_alpha after pre-multiplication we can
simplify main() considerably.
The cost is that for straight-alpha input or color_pipeline() we might
be doing three multiplications more than before. However,
a) the cost of running color_pipeline() probably dominates anyway, and
b) to get straight-alpha input you have to use a future Wayland
extension that probably won't be advertised without color management.
So we keep the optimization for the simple case (no color management)
while potentially incurring a small cost on the heavy case (with color
management).

"max bpc" property is meant for working around faulty sink hardware.
Normally it should be set to the maximum possible value so that the
kernel driver has full freedom to choose the link bpc without being
artificially forced to lower color precision.
The default value is 16 because that is a nice round number and more
than any link technology I've heard is using today which would be 12.
Also offer an API set the value, so that weston.ini could be used in the
next patch for sink workaround purposes.

Before this change the drm-backend in Weston did the work of parsing DRM
blobs in order to query IN_FORMATS data, if available. This is also the

libdrm 2.4.108 with e641e2a6 ("xf86drm: add iterator API for DRM/KMS
IN_FORMATS blobs") introduced a dedicated API for querying IN_FORMATS data.
Bump the minimum required version to 2.4.108, stop parsing IN_FORMATS in
Weston and start using DRM iterators. In addition, remove fallback code for
libdrm <2.4.107.
