24b08d1a36 Move event handling to a new file
display.c is getting a bit crowded. Move most of the handling
out to another file, events.c.

The long-term goal is to have generic event handling here, with
backend-specific handling for the types of windows and such.

76dc0ca681 wayland: Exempt CLICKING grab ops when syncing wayland input focus
If we have a CLICKING grab op we still need to send events to xwayland
so that we get them back for gtk+ to process thus we can't steer
wayland input focus away from it.

1b29113150 wayland: Set/unset wayland focus on mutter grab/ungrab operations
This ensures that we send the proper leave and enter events to wayland
clients.

Particularly, this solves a bug in SSD xwayland windows where clicking
and dragging on the title bar to move the window only works on the odd
turn (unless the pointer moves away from the title bar between
tries). This happens because xwayland gets a button press but doesn't
see the release so when it gets the next button press it discards it
because its pointer button tracking logic says that the button is
already pressed. Sending the proper wayland pointer leave event fixes
it since wayland clients must forget about button state at that point.

46af3ef9f6 keybindings: Keep keybindings in an hash table instead of an array
This allows us to look for a match with an O(1) search instead of O(n)
which is nice, particularly when running as a wayland compositor in
which case we have to do this search for every key press event (as
opposed to only when our passive grab triggers in the X compositor
case).

We actually need two hash tables. On one we keep all the keybindings
themselves which allows us to add external grabs without constantly
re-allocating the array we were using previously.

The other hash table is an index of the keybindings in the first table
by their keycodes and mask which is how we actually match the key
press events. This second table thus needs to be rebuilt when the
keymap changes since keycodes have to be resolved then but since we're
only keeping pointers to the first table it's a fast operation.

5c99eae8a9 display: clean up event handling
The only events we handle as XIEvents are FocusIn/Out, Enter and
Leave.  Motion, ButtonPress/Release, KeyPress/Release are handled
through clutter instead.
Among other things, this means we don't need to fake motion compression

9c1b972ca1 Fix problems with focus tracking
When a client spontaneously focuses their window, perhaps in response
to WM_TAKE_FOCUS we'll get a FocusOut/FocusIn pair with same serial.
Updating display->focus_serial in response to FocusOut then was causing
us to ignore FocusIn and think that the focus was not on any window.

We need to distinguish this spontaneous case from the case where we
set the focus ourselves - when we set the focus ourselves, we're careful
to combine the SetFocus with a property change so that we know definitively
what focus events we have already accounted for.

e86c53230f display: Move the pointer event handling code to work in terms of Clutter events
There is now a meta_display_handle_event alongside the
meta_display_handle_xevent function which handles events in terms of
Clutter events instead of X events. A Clutter event filter is
registered so that all Clutter events will pass through this function.
The pointer event handling code from the X event version has been moved
into this new function and has been modified to use the details from
the Clutter event instead of the X event. This is a step towards
moving all of the event handling code over to use Clutter events.

876f81db12 compositor: fix focusing the stage window
We can't use the X11 stage window, if clutter is not using the X11
backend (and even if it was, it would be bogus when the xwayland
server is not the one clutter is talking to). Instead, we introduce
the concept of "focus type", which we use to differentiate the
various meanings of None in the focus_xwindow field.

268ebb1b18 wayland: Add basic input support
This copies the basic input support from the Clayland demo compositor.
It adds a basic wl_seat implementation which can convert Clutter mouse
events to Wayland events. For this to work all of the wayland surface
actors need to be made reactive.

The wayland keyboard input focus surface is updated whenever Mutter
sees a FocusIn event so that it will stay in synch with whatever
surface Mutter wants as the focus. Wayland surfaces don't get this
event so for now it will just give them focus whenever they are
clicked as a hack to test the code.

7a4c808e43 display: clean up focus_window vs expected_focus_window
Mutter previously defined display->focus_window as the window that the
server says is focused, but kept display->expected_focus_window to
indicate the window that we have requested to be focused. But it turns
out that "expected_focus_window" was almost always what we wanted.

Make MetaDisplay do a better job of tracking focus-related requests
and events, and change display->focus_window to be our best guess of
the "currently" focused window (ie, the window that will be focused at
the time when the server processes the next request we send it).

592374bc62 Fix freezing of windows with keyboard resizing
During resizing we froze window updates when configuring the
window, and unfroze the window updates when processing the
next resize. This wasn't absolutely reliable, because we might
not have a next resize. Instead tie window freezing more
directly to the current sync request value - a window is
frozen until it catches up with the last value we sent it
in _NET_WM_SYNC_REQUEST.

Testing with unresponsive clients showed that there was a bug
where window->disable_sync once set, would not actually disable
sync, but it *would* disable noticing that the client was
unresponsive for the next resize. Fix that by checking for
->disable_sync before sending _NET_WM_SYNC_REQUEST.

2cafb8be2d window: fix meta_window_is_remote across hostname changes
meta_window_is_remote compares a cached copy of the system hostname
with the hostname of the client window
(as presented by the WM_CLIENT_MACHINE property).

Of course, the system hostname can change at any time, so caching
it is wrong. Also, the WM_CLIENT_MACHINE property won't necessarily
change when the system hostname changes, so comparing it with the
new system hostname is wrong, too.

This commit makes the code call gethostname() at the time
WM_CLIENT_MACHINE is set, check whether it's remote then, and cache
that value, rather than comparing potentially out of sync hostnames
later.

57c31a56f4 barrier: Add support for new barrier features in XInput 2.3
XInput 2.3 adds support for "barrier events", which let us know when
a pointer barrier has been hit, and when the pointer has stopped
hitting the barrier, and lets us "release" the barrier, temporarily
letting the pointer pass through the barrier. These features can be
combined to allow for certain pointer gestures, such as "pushing"
against the bottom of the screen, or stopping the pointer on monitor
edges while dragging slowly for increased edge precision.

This commit should allow graceful fallback if servers with
XInput 2.3 aren't supported.

Moving focus immediately on crossing events as we currently do

c84da3ce1b Move the installed includes to a subdir
If mutter is going to be a "real" library, then it should install its
includes so that users can do

    #include <display.h>

So rename the includedir accordingly, move src/include to src/meta,
and fix up all internal references.

There were a handful of header files in src/include that were not
installed; this appears to have been part of a plan to keep core/,
ui/, and compositor/ from looking at each others' private includes,

1c3f7c4088 Allow breaking out from maximization during a mouse resize
A maximized window can't be resized from the screen edges (preserves
Fitts law goodness for the application), but it's still possible
to start a resize drag with alt-middle-button. Currently we just
don't let the user resize the window, while showing drag feedback;
it's more useful to let the user "break" out from the resize.

This provides a fast way to get a window partially aligned with
the screen edges - maximize, then alt-drag it out from one edge.

Behavior choices in this patch:

 - You can drag out a window out of maximization in both directions -
   smaller and larger. This can be potentilaly useful in multihead.

 - Dragging a window in only one direction unmaximizes the window
   fully, rather than leaving it in a horizontally/vertically
   maximized state. This is done because the horizontally/vertically
   maximzed states don't have clear visual representation and can
   be confusing to the user.

 - If you drag back to the maximized state after breaking out,
   maximization is restored, but you can't maximize a window by
   dragging to the full size if it didn't start out that way.

A new internal function meta_window_unmaximize_with_gravity() is
added for implementing this; it's a hybrid of
meta_window_unmaximize() and meta_window_resize_with_gravity().

2a823ef3e4 Fix crash when struts change during grab operation
Since meta_workspace_invalidate_work_area() frees the edges
workspace->screen_edges and workspace->monitor_edges, we must clean up
our cached edge resistance data when the invalidate_work_area() is
called on the active workspace, or when the workspace changes.

Make the computation of the edge resistance data lazy so that it
will be recomputed the next time we try to access it.
meta_display_compute_resistance_and_snapping_edges() is made
private to edge-resistance.c

Invaliding the data when active workspace changes also will improve
correctness for edge resistance when the current workspace changes
during a grab operation. (Even with this fix we still don't try to
handle window positions changing during a grab operation; that can't
cause a crash since, unlike screen and monitor edges, the window edges
are freshly allocated, it will just cause slight oddness in that
corner case.)

Root cause tracked down due to much effort by Jon Nettleton.
