DRM leasing is a feature which allows the DRM master to "lease" a subset
of its DRM resources to another DRM master via drmModeCreateLease, which
returns a file descriptor for the new DRM master. We use this protocol
to negotiate the terms of the lease and transfer this file descriptor to
clients.
In less DRM-specific terms: this protocol allows Wayland compositors to
give over their GPU resources (like displays) to a Wayland client to
exclusively control.
The primary use-case for this is Virtual Reality headsets, which via the
non-desktop DRM property are generally not used as desktop displays by
Wayland compositors, and for latency reasons (among others) are most
useful to games et al if they have direct control over the DRM resources
associated with it. Basically, these are peripherals which are of no use
to the compositor and may be of use to a client, but since they are tied
up in DRM we need to use DRM leasing to get them into client's hands.

After a requesting client receives a new token, the client usually forwards the
token string to another client by a different process, which then uses the
token in an activate request. For that the token string must be transferred to
the other process.
Two default ways of doing that were described in the done event, but the
description had some issues and it makes more sense to describe them in the
protocol description itself, which talks about the protocol in a more general
way. Therefore rewrite the paragraphs about token forwarding between clients
and place them in the protocol description.

Instead of describing each enum entry in the enum description,
use enum entry descriptions. This avoids the awkward list of
flags in the top-level description.
This has been possible for a long time, but wasn't correctly
handled by wayland-scanner until recently [1].

It is illegal for a surface to have more than one role. The only thing
which can be done with an xdg_surface (apart from destroying it) is to
assign the surface a role with the get_toplevel, get_popup, etc
requests.
On Mutter, calling get_xdg_surface on a surface which already has an
assigned role generates the 'role' protocol error. Weston will not send
an error, however it may later abort on a failed assert during cleanup.
wlroots allows this case, and only sends the role error when assigning
an explicit role through creating a toplevel or popup.
On the grounds that it makes no sense to create an xdg_surface for a
wl_surface which already has a role, make it explicitly illegal.

Stop hardcoding the Python path to /usr/bin/python3. Not all systems
have Python installed to /usr/bin, and some users might have installed
Python to a custom location.
Instead, use /usr/bin/env, which performs a $PATH lookup to find the

Time has told us that the effort going from `unstable` to `stable` is
enough of a burdon meaning very few protocols are ever declared stable.
To mitigate this, and thus avoid having protocols being "stuck" being
"unstable" indefinitely, replace the "unstable" -> "stable" procedure
with a "staging" -> "stable" procedure, where declaring a protocol
stable does not involve any changes to any implementations.
The only side effect of this is that version numbers are to forever be
part of all interface names and protocol XML files.

This is being picky, but "pinch/spread" is the physical gesture, zoom and
rotate is the effect that clients provide in response to that gesture.
Let's use pinch only here since spread is more ambiguous in english, as anyone
who's ever had butter on their bread would know.
Also, everything else is referring to it as pinch anyway, so zoom/rotate here
is the odd one out.

Currently, the spec doesn't say explicitly that present requests assign
a surface role. Given that, it can be viewed as the protocol modifies
an already assigned surface role, e.g. xdg-toplevel, and present requests
only act as hints.

This commit makes it clear that compositors can send valid modifiers and
DRM_FORMAT_MOD_INVALID for a given format. This means that the compositor
supports both implicit and explicit modifiers. See the warning further
down:
> Warning: It should be an error if the format/modifier pair was not
> advertised with the modifier event. This is not enforced yet because
> some implementations always accept DRM_FORMAT_MOD_INVALID. Also
> version 2 of this protocol does not have the modifier event.
Xwayland already requires compositors to send DRM_FORMAT_MOD_INVALID
for importing buffers with an implicit modifier [1].
In a future protocol version, it would be nice to make it a protocol
error (or at least a soft failure) to use any format/modifier pair that
wasn't advertised. A use-case for this is Vulkan compositors: the Vulkan
DMA-BUF extensions require an explicit modifier and cannot import
buffers which have an implicit modifier.

ci-fairy doesn't know how to to look at $CI_MERGE_REQUEST_PROJECT_PATH
right now, so if we don't manually set $FDO_UPSTREAM_REPO, ci-fairy will
(without verbose logging turned on) silently fall back on the source
repository project path for finding the branch point. This might fail if
the owner of the source repository hasn't updated the `master` branch of
their fork.

"datadir" is not the same thing in meson and autotools.
In autoconf "datadir" is "${datarootdir}", which expands to
"${prefix}/share". @datarootdir@ expands to "${prefix}/share". There
seems to be no variable that expands to "share".
In meson "datadir" is "share".
So, avoid the "datadir" variable, just expand "datarootdir" it manually
instead. This unbreaks the recently broken autotools setup.

This was prompted by the discussion from
https://lists.freedesktop.org/archives/dri-devel/2020-May/266611.html
which is not the final wording.
When a DRM device is hot-unplugged, particularly if it is the Wayland
compositor's compositing GPU, EGL may start returning errors from trying to use
the client's dmabuf. Or, if the client is rendering on another GPU which gets
hot-unplugged, the dmabuf the compositor already has may start failing.
Hot-unplug is an abrupt global action, and there is no way a client or a
compositor could ensure they clean up before things start failing. It is not
the client's fault, so the client should not get disconnected if already
existing wl_buffer objects start failing. This patch add the wording to the
protocol to this effect.
The intention is that the compositor replaces the failed buffers with some
placeholder content. There is no way this could be glitch-free. In its own pace
the client should discover the DRM device is gone, clean up, and perhaps use
something else. How exactly that should happen depends on the rendering API the
client is using.
This is a tiny step towards making DRM device hot-unplug not crash
applications that wish to handle the unplug gracefully.

Currently protocol does not specify what should happen if multiple
text-inputs are created by same client, which is why this is more or
less undefined behavior currently in compositor implementations.
If client has created more than one text-input objects and surface owned
by the client is focused, then compositor must send enter event to all
text-input objects, in case of enable request however only one
text-input must be enabled per client per seat.

This commit adds protocol additions making it possible to request that a
popup should be repositioned according to a new xdg_positioner object.
Explicit popup moving is done using a new request on xdg_popup:
xdg_popup.reposition. What it does is change the parameters used for
positioning a popup by providing a new xdg_positioner object. This
request is coupled with a new event; xdg_popup.repositioned, sent
together with the configure events (xdg_popup.configure and
xdg_surface.configure) to notify about the completion of the reposition
request. The reposition request also takes a token that is later passed
via the repositioned event; this is done so that a client may determine
for which reposition request the compositor has sent configure events.
Synchronization between surfaces to avoid state application race
condition are deliberately left out, and should be handled by an
external protocol.
To brief the compositor of the future dimension of the parent that the
compositor should position the popup against, a
xdg_positioner.set_parent_size request is added.
Lastly, a request to couple a xdg_positioner object with a parent
configure event is added (xdg_positioner.set_parent_configure) in
order for a compositor to pair a popup reposition request with a pending
configure event, and it's resulting window geometry. This is necessary
to, for example, properly constrain a popup given a future parent state.
An example of when this may be necessary is an interactive resize where
both the toplevel position and the relative popup position changes.
