Since version 7 clients must use MAP_PRIVATE to map the keymap fd so we
can use memfd_create in os_ro_anonymous_file_get_ref using
RO_ANONYMOUS_FILE_MAPMODE_PRIVATE, for older version we use
RO_ANONYMOUS_FILE_MAPMODE_SHARED to be compatibile with MAP_SHARED.

New in version 6 are touch shape, touch orientation and axis source
wheel tilt. Weston doesn't support any of them yet but simply not
sending the new events and new enum value is sufficient to claim to
support this version.
Also bump the Wayland requirement to 1.17 to ensure both version 6 and 7
definitions are in the XML.
The reason for bumping to v6 without implementing the new features is
that we must support v7 to make use of struct ro_anonymous_file
introduced in the previous commit.

The ro_anonymous_file is an abstraction around anonymous read-only files.
os_ro_anonymous_file_create creates such a file with the contents passed
in data. Subsequent calls to os_ro_anonymous_file_get_fd return a fd
that's ready to be send over the socket.
When mapmode is RO_ANONYMOUS_FILE_MAPMODE_PRIVATE the fd is only
guaranteed to be mmap-able readonly with MAP_PRIVATE but does not
require duplicating the file for each resource when memfd_create is
available. RO_ANONYMOUS_FILE_MAPMODE_SHARED may be used when the client
must be able to map the file with MAP_SHARED but it also means that the
file has to be duplicated even when memfd_create is available.

Now that all cases of unresolved symbols have been either fixed or worked
around pending for a proper fix, we can switch the project to disallow
unresolved symbols during build. This will help catch programming mistakes
earlier.

change. If you have an existing build directory, you must issue
meson configure -Db_lundef=true

surface-screenshot-test.c uses file_create_dated() provided by libshared, so it
needs to link libshared.

This takes everything that was in 'weston' the executable a turns it into
library. A new trivial 'weston' executable is written.
Creating the library will allow future improvements:
- we can link weston plugins against the library, meaning that they no longer
need unresolved symbols to be allowed during linking
- tests do not have to fork() and exec() 'weston', they can just link to the
library and call wet_main() after setting things up; this will help with
using a debugger
install_rpath is set so that we can install the library into weston's module
directory, away from the normal libraries in a system. This is one library we
do not intend for others to use.
The library has no stable ABI and is not versioned.

We have two kinds of libweston users: internal and external. Weston, the
frontend, counts as an external user, and should not have access to libweston
private headers. The shell plugins are external users as well, because we
intend people to be able to write them. Renderers, backends, and some plugins
are internal users who will need access to private headers.
Create two different Meson dependency objects, one for each kind.
This makes it less likely to accidentally use a private header.
Screen-share is a Weston plugin and therefore counts as an external user, but
it needs the backend API to deliver input. Until we are comfortable exposing
public API for that purpose, let it use internal headers.

This (so-far) Linux-only API lets users create file descriptors purely
in memory, without any backing file on the filesystem and the race
condition which could ensue when unlink()ing it.
It also allows seals to be placed on the file, ensuring to every other
process that we won’t be allowed to shrink the contents, potentially
causing a SIGBUS when they try reading it.
This patch is best viewed with the -w option of git log -p.

An object based on 'weston_timeline_subscription' will be created for
each subscription created. It contains the next object ID and list of
'weston_timeline_subscription_object'.
It will automatically be cleaned by the logging framework when the
subscription gets destroyed, or use the object destroy signal to trigger
the destruction of the timeline subscription (@pq), when the object
itself is being destroyed.
This class will hanged-off the subscription, such that we can
retrieve it when going over all the subscriptions.
An object based on 'weston_timeline_subscription_object' will help
maintain the state of the objects seen and will be created when a new
object will be emitted for a particular 'weston_timeline_subscription'.

weston_compositor_build_view_list can reconstruct the view_list without a view which was
previously in it. The existing pointers in view->link are left unchanged, which could
lead to corruption or access to released memory in wl_list_remove, depending of the
