Since the logic of pointer constraints assumes a valid view throughout, add a
signal to disable constraints when its current view is unmapped by Weston.
The assumption that a previously unmapped view is valid already leads to the
constraints code crashing. This can happen when attaching a NULL buffer to the
surface and commiting, which effectively unmaps the view with the side effect of
clearing the surface's input region, which is then assumed valid inside

If two or more clients were running and the one that was focused when
weston itself lost keyboard focus was killed, weston would crash.
This is because commit 85d55540cb changed the way we handle saved keyboard
focus when we lose focus, and did so in such a way that the saved keyboard
focus listener could be removed from the surface destroy signal list
during the emit of the surface destroy signal. This corrupted the list
and led to a NULL pointer dereference.
Fix this by using a boolean flag to determine whether we should obey the
saved keyboard focus. We can set this safely in cases where
removing the listener would cause a crash.

When setting a cursor surface, use the surface dimensions, instead of the
weston_surface buffer reference, to check if the surface has any
content. A weston_surface without any buffer reference may in fact
have a buffer which was committed in a previous pointer entry, dropped
by weston_surface and now held only internally by the renderer.
Without this fix, when a pointer enters a surface, the cursor image is
not correctly updated if we set a cursor surface with an already
committed buffer from a previous pointer entry, without recommitting the
cursor buffer for the current entry. This can be seen, for example, in
the experimental Wine Wayland driver which handles the cursor in a way
that leads to the following scenario:
Setup: cursor_surface.attach(buffer) & cursor_surface.commit()
On first wl_pointer.enter: pointer.set_cursor(cursor_surface)
compositor/renderer redraws
wl_pointer.leave
On second wl_pointer.enter: pointer.set_cursor(cursor_surface)
When handling the second pointer.set_cursor() request the current code
doesn't find a buffer attached to the cursor_surface (only the renderer
now has a reference to it), so it doesn't update the respective view for
the cursor.

The printf() format specifier "%m" is a glibc extension to print
the string returned by strerror(errno). While supported by other
libraries (e.g. uClibc and musl), it is not widely portable.
In Weston code the format string is often passed to a logging
function that calls other syscalls before the conversion of "%m"
takes place. If one of such syscall modifies the value in errno,
the conversion of "%m" will incorrectly report the error string
corresponding to the new value of errno.
Remove all the occurrences of the specifier "%m" in Weston code
by using directly the string returned by strerror(errno).

The main idea is to make libweston users use the form

Client may map any file descriptor opened for writing with PROT_WRITE
themselves. On linux, even a read-only file descriptor to an unlinked
file can be re-opened with write permission through /proc/self/fd.
The only way to prevent this is to create a memfd which
is subsequently write-sealed. Unfortunately this prevents clients
from mapping with MAP_SHARED, which is already in widespread usage.
To isolate and protect the keymap, whilst allowing MAP_SHARED clients
to continue to work, use a unique file descriptor for each

This implements a new global interface weston_touch_calibration, which
allows one client at a time to perform touchscreen calibration. This
also implements the calibrator window management.
A client asks to calibrate a specific physical touch device (not a
wl_seat which may have several physical touch devices aggregated).
Libweston grabs all touch devices and prevents normal touch event
handling during the calibation sequence.
API is added to enable this new global interface, but it not yet called
by anything. Since the implementation allows clients to grab touch devices
arbitrarily, it is not enabled by default. The compositor should take
measures to prevent unexpected access to the interface.
A client may upload a new calibration to the compositor. There is a
vfunc to allow the compositor to reject/accept it and save it to
persistent storage. The persistent storage could be a udev rule
setting LIBINPUT_CALIBRATION_MATRIX, so that all display server would
load the new calibration automatically.

In addition to the normal touch event processing mode, introduce a new
mode for calibrating a touchscreen input device.
In the calibration mode, normal touch event processing is skipped, and
the raw events are forwarded to the calibrator instead. The calibrator
is not yet implemented, so the calls will be added in a following patch.
To switch between modes, two functions are added, one for entering each
mode. The mode switch happens only when no touches are down on any touch
device, to avoid confusing touch grabs and clients. To realise this, the
state machine has four states: prepare and actual state for both normal
and calibrator modes.
At this point nothing will attempt to change the touch event mode.
The new calibrator mode is necessary, because when calibrating a
touchscreen, the touch events must be routed to the calibration client
directly. The touch coordinates are expected to be wrong, so they cannot
go through the normal focus surface picking. The calibrator code also
cannot use the normal touch grab interface, because it needs to be able
to distinguish between different physical touch input devices, even if
they are part of the same weston_seat. This requirement makes
calibration special enough to warrant the new mode, a sort of "super
grab".

notify_touch_normalized() is an extended form of notify_touch(), adding
normalized touch coordinates which are necessary for calibrating a
touchscreen.
It would be possible to invert the transformation and convert from
global coordinates to normalized device coordinates in input.c without
adding this API, but this way it is more robust against code changes.
Recovering normalized device coordinates is necessary because libinput
calibration matrix must be given in normalized units, and it would be
difficult to compute otherwise. Libinput API does not offer normalized
coordinates directly either, but those can be fetched by pretending the
output resolution is 1x1.
Anticipating touch calibration mode, the old notify_touch() is renamed
into a private process_touch_normal(), and the new
notify_touch_normalized() delegates to it.

Introduce weston_touch_device for libweston core to track individual

the physical devices will be required for implementing touchscreen
calibration. One can only calibrate one device at a time, and we want to
make sure to handle the right one.
Both backends that support touch devices are updated to create
weston_touch_devices. Wayland-backend provides touch devices that cannot
be calibrated, because we have no access to raw touch coordinates from
the device - calibration is the responsibility of the parent display
server. Libinput backend provides touch devices that can be calibrated,
hence implementing the set and get calibration hooks.
Backends need to maintain an output pointer in any case, so we have a
get_output() hook instead of having to maintain an identical field in
weston_touch_device. The same justification applies to
get_calibration_head_name.
