46cb506f8f wayland: use the inhibit shortcuts dialog
Plug the new MetaInhbitShortcutsDialog to the relevant Wayland protocol
implementation.

Also, remember the last user choice for a given surface to avoid asking
continuously the same question.

dd12f569d9 wayland: add inhibit shortcut mechanism
Add a mechanism to MetaWaylandSurface that inhibits compositor's own
shortcuts when the surface has input focus, so that clients can receive
all key events regardless of the compositor own shortcuts.

This will help with implementing "fake" active grabs in Wayland and
XWayland clients.

495c89401a Implement support for the wp_pointer_constraints protocol
The wp_pointer_constraints protocol is a protocol which enables clients
to manipulate the behavior of the pointer cursor associated with a seat.

Currently available constraints are locking the pointer to a static
position, and confining the pointer to a given region.

Currently locking is fully implemented, and confining is implemented for
rectangular confinement regions.

What else is lacking is less troublesome semantics for enabling the lock
or confinement; currently the only requirement implemented is that the
window that appears focused is the one that may aquire the lock.

This means that a pointer could be 'stolen' by creating a new window that
receives active focus, or when using focus-follows-mouse, a pointer
passes a window that has requested a lock. This semantics can be changed
and the protocol itself allows any semantics as seems fit.

50099c4c10 wayland: use glib function for fetching timestamp
The code currently implements a function, get_time, that
fetches a timestamp.  That duplicates code already in glib,
and the glib implementation is better, anyway, since it doesn't
skew backward when the system clock is changed.

This commit changes the code to use g_get_monotonic_time and
drop the get_time function.

49ea6486e2 wayland: bind wayland socket after xwayland is initialized
During xwayland initialization we run main loop and dispatch wayland
events, so that xwayland can initialize. If some client during this
phase connects and creates surface, mutter crashes because
it is not initialized yet. If we bind wayland socket after xwayland
is initialized and main loop is not running anymore, no client can
connect to mutter during initialization and that is what we want.

614d6bd0f8 Nested X11: use KeymapNotify events to fix key state on FocusIn
If the user Alt-Tabs out of the window, we will be left thinking
the Alt key is still pressed since we don't see a release for it.

Solve this and other related issues for the nested X11 compositor
by selecting for KeymapStateMask which causes a KeymapNotify event
to be sent after each FocusIn, and when we get these events, update
the internal XKB state and send any necessary modifiers events to
clients.

57359da9b4 wayland: Kill the buffer destroy error
Previously, a sequence like this would crash a client:

  => surface.attach(buffer)
  => buffer.destroy()

The correct behavior is to wait until we release the buffer before
destroying it.

  => surface.attach(buffer)
  => surface.attach(buffer2)
  <= buffer.release()
  => buffer.destroy()

The protocol upstream says that "the surface contents are undefined"
in a case like this. Personally, I think that this is broken behavior
and no client should ever do it, so I explicitly killed any client
that tried to do this.

But unfortunately, as we're all well aware, XWayland does this.
Rather than wait for XWayland to be fixed, let's just allow this.

Technically, since we always copy SHM buffers into GL textures, we
could release the buffer as soon as the Cogl texture is made.

Since we do this copy, the semantics we apply are that the texture is
"frozen" in time until another newer buffer is attached. For simple
clients that simply abort on exit and don't wait for the buffer event
anyhow, this has the added bonus that we'll get nice destroy animations.

b3364cad3e wayland: Update keyboard state unconditionally
In particular we need to know about all key events to keep the xkb
state reliable even if the event is then consumed by a global shortcut
or grab and never reaches any wayland client.

We also need to keep track of all pressed keys at all times so that we
can send an updated set or pressed keys to the focused client when a
grab ends.

776a86a65f wayland: heavily refactor pointer grabs
Grabs are now slice allocated structures that are handled by

with the interface and a backpointer to the MetaWaylandPointer.
The grab interface has been changed to pass full clutter events,
which allowed to remove the confusion between grab->focus and
pointer->focus. Invidual grabs are now required to keep their
focus, and choose whoever gets the events.

We can be launched by gnome-session now, which implies gdb must be
attached from outside, and the Ctrl-C problem is gone.

227fb56103 Set DISPLAY and WAYLAND_DISPLAY for dbus activated services and for autostarted apps
Call the appropriate method on gnome-session so that autostarted
and bus activated apps see the X server and wayland socket.

73ee491281 wayland: fix interface versioning
Add MIN(...) with the interface version actually implemented
to all resource constructor, so that we never risk seeing requests
we don't implement (and consequently segfault)

450afbaf51 wayland: reimplement keyboard state handling properly
We can't rely on clutter's xkb_state, because that's updated
when events are pulled from the kernel, not when we see them.
Instead, use the new clutter API to get the full modifier state
from the event (which, as a side effect, also works when clutter
is using the X11 backend for running nested).

for wl_surface, so generalize the book-keeping structures.

cbe5b6b3bc meta-wayland: intersect the damage region with the window size before applying
According to the wayland documentation, damage outside the
window size is ignored.
This happened with xwayland+wlshm (causing a GL error when calling
TexSubImage2D), probably due to not resizing the buffer
until we receive the corresponding X event.
Might also be an off-by-one in xwayland, as the window size did
not actually change.

Note: we might want to take the configure_notify path instead,
and keep the GL/clutter size consistent with wayland rather than
X, because in the end that's what matters for events and composition.

b1206ceb66 wayland: Ensure that opaque / input regions are set at commit time
The protocol specification says that opaque / input regions should be
considered pending state and should only be actually swapped out when
the surface is committed, so it can be set atomically.

ad4053ab84 wayland: fix pointer focus for destroyed surfaces
We had an assertion in meta_wayland_surface_free() that after
a repick() we would not choose the freed surface, but that didn't
consider surfaces destroyed while holding the implicit pointer
grab (ie, because the user clicked on the X button). In that case,
we need to bypass the grab infrastructure and explicitly unfocus
the dead surface.
