Fix crashes in phosh protocol related to xdg-shell metadata

See merge request Librem5/wlroots!36

Unmapped surfaces have no app_id and no title, so comparisons are not possible.

Enable gitlab-ci on f/phosh-private

See merge request !37

Needed for the screencopy example that will be pulled in with our next
update from upstream's master as of
a7a96d76.

Build it once with and without xwayland so we're sure both work

Simple private protocoll to list and raise toplevels by app_id and
title. We wanted a minimal set of objects, requests and events. Since
this is only meant for the app overview page in the shell we can take
many shortcuts and leave out e.g. XWayland for the moment.

This will be replaced by wlr_foreign_toplevel_unstable_v1 later on.

We don't rename the request itself since we don't want to change the
protocol.

This makes it better match the protocol name. Also name the
variables consistently "phosh" instead of the overused "shell".

Phosh private cleanup

See merge request !14

When the panel surface vanishes we need to remember that so we
don't reference it accidentally later.

Also properly distinguish between a client going a way
(phosh_resource_destroy) and the cleaning up the whole global
(phosh_destroy).

Closes #11

We never submitted it upstream.

This fixes surface positioning after rotation, closes #1

linux-dmabuf: add v1 suffix

This prevents some future conflicts with the stable version.

Fixes #1133

Introduce set_hints event for xwayland

xwayland: handle override_redirect flag changes

The override_redirect flag can change on configure notify and
on map notify. This adds an event to know when it changes.

This removes wlr_xwayland_surface_is_unmanaged which was wrongly
using the window type to decide whether the view should be
unmanaged.

A similar patch was proposed to Weston, but has never been
merged upstream [1].

Document WLR_HEADLESS_OUTPUTS

Remove unused types/wlr_tablet_v2.c

tablet-unstable-v2 support

There were a few issues after rebase, that the merge algorithm didn't
throw at my face:

wlr_output did a check on the actual role, not a string anymore, so that
had to go to allow tablet-v2 to set cursor surfaces.
A few L_DEBUG/L_ERRORs were still around
There was a user-after-free in tablet-group free()ing, probably after
insufficient testing from a previous feedback pass

The previous naming was based on the input-device capability names from
libinput.
With code that uses the libinput_tablet_tool and mapping into tablet-v2,
this is confusing, so the name is changed to follow the names used in
the protocol.

Introduce TABLET_MANAGER_VERSION and remove the wlr_tablet_tool_tool.c
