In the original conception, a weston_buffer_reference indicated that the
underlying contents of the wl_buffer would or could be accessed, so
wl_buffer.release must not be sent until the last reference was
released, as the compositor may still use it.
This meant that renderers or backends which copied the buffer content -
such as the GL renderer with SHM buffers - could only send a buffer
release event to the client by 'losing' the buffer reference altogether.
The main side effect is that `weston-debug scene-graph` could not show
any information at all about SHM buffers when using the GL renderer, but
it also meant that renderers and backends grew increasingly exotic
structures to cache information about the buffer.
Now that we have an additional buffer-reference mode (still referring to
the weston_buffer/wl_buffer, but not going to access its content), we
can allow the weston_buffer_reference and weston_buffer to live as long
as the buffer itself, even if we do send a release event.
This will enable a bunch of backend and renderer deduplication, as well
as finally making scene-graph more useful.

Add a mode argument to weston_buffer_reference which indicates whether a
buffer's storage may/will be accessed, or whether the underlying storage
will no longer be accessed, e.g. because it has been copied. This will
be used to retain a pointer to the weston_buffer whilst being able to
send a release event to the client.

We currently allow a weston_buffer to outlive the underlying wl_buffer
iff the renderer/backend has cached it. Currently the 'is this buffer
valid?' test relies on looking for the validity of the weston_buffer
itself; shift these tests to looking at the validity of the underlying
resource.

y_inverted meant that the buffer's origin was (0,0), and non-inverted
meant that the buffer's origin was (0,height). In practice, every buffer
was 'inverted' into our natural co-ordinate space that we use
everywhere.
Switch to using an explicit origin enum to make this more clear.

When we first see a buffer attached, we create a weston_buffer for it.
The weston_buffer doesn't contain any useful information in and of

We want to wait for Xwayland to be ready before issuing it blocking
requests, but relying on USR1 is a bit unsafe:
- we can't ascertain the signal originated from Xwayland
- if weston is started as PID1 (e.g. in its own container), then
Xwayland will not send SIGUSR1 and X11 connections will be stuck

When we launch clients they currently stay in the same session as
weston, and share its controlling terminal. This means hitting ctrl-c
in weston's controlling terminal will send SIGINT to the clients as
well. It also means SIGHUP will be propagated to our launched clients
if weston's controlling terminal is closed.
While generally not harmful, this behaviour is not beneficial, and
is present by default and not by design.
Problems arise when launching weston in a debugger, as a ctrl-c sent to
the debugger will be propagated not only to the debugger, but all the child
processes sharing weston's session. This results in weston-desktop-shell
being killed by the ctrl-c that was intended to stop weston for debugging.
If weston-desktop-shell is killed within 30 second of startup, it will
result weston performing a clean shutdown. This clean shutdown can
make debugging a little too surprising.
Ostensibly, clients launched via weston_client_launch will be wayland
clients that terminate cleanly on their own if weston is killed, so
there should be no need for them to remain in weston's session to
catch ctrl-c from its controlling terminal. Nor should they need a
controlling terminal for their general operation.
Use setsid() to move them to their own session, devoid of controlling
terminal, to make using a debugger a little less confusing in some
cases.

signalfd interacts badly with gdb's signal trapping - when hitting
ctrl-c in a debugger attached to weston, weston will receive the
signal. This results in weston exiting cleanly when the intent
was to use gdb to interfere with its operation.
Trapping SIGINT was introduced in commit 50dc6989 which ensured we
would call wl_display_terminate() on SIGINT or SIGTERM to clean
up our socket.
Killing weston with SIGINT is quite common for several developers,
so it's important to preserve this clean shutdown behaviour, so
we can't naively stop trapping SIGINT entirely.
Instead, use the sigaction() function to trap SIGINT, and have
the SIGINT handler send weston SIGUSR2 (SIGUSR1 is already
used by xwayland). SIGUSR2 can be trapped in the proper wayland
way via wl_event_loop_add_signal(). This way we can properly
break our event loop and clean up on SIGINT, but we can also
have gdb intercept SIGINT.
There are other ways around this, but I'm hoping this one allows
people to continue using ctrl-c to stop weston, and doesn't
require additional project specific gdb knowledge.

We've been trapping SIGQUIT for a "clean shutdown" since commit 3cad436a
However, sources such as:
http://www.gnu.org/software/libc/manual/html_node/Termination-Signals.html
indicate we probably shouldn't be trapping it at all, as the intent of
SIGQUIT is to leave a core file and debug artifacts from the run.
We should perform the minimal amount of clean up to ensure the system isn't
left in an unusable state - but these days that's performed by other
software such as logind.
We can safely stop trapping SIGQUIT entirely.

The repaint_data is entirely backend specific. Moreover, it is only used by the
drm backend, while other backends ignore the repaint data.
There will always be only one repaint active, thus, there is no need to pass the
repaint data from the outside.
The repaint_data breaks with the multi-backend series, which calls repaint begin
for all backends to get the repaint_data. The repaint_data of the last backend
will then be passed to all other backend. At the moment, this works, because the
drm backend is the only backend that implements the begin_repaint call.
Another option would be to track the repaint data per backend in the compositor,
but actually, it the backend needs to track state across the calls, it's its own
responsibility.
