Refactor make_default_config() to always sanity-check the configuration to
ensure that it fits within the framebuffer. Previously, this was only done
for the default linear configuration.
In recent versions of the QXL driver, it may set "suggested X|Y" connector
properties. These properties are used to indicate the position at which
multiple displays should be aligned. If all outputs have a suggested position,
the displays are arranged according to these positions, otherwise we fall back
to the default configuration.
At the moment, we trust that the driver has chosen sane values for the
suggested position.
When the output device has hotplug_mode_update (e.g. the qxl driver used in
vms), the displays can be dynamically resized, so the current display
configuration does not often match a stored configuration. When a new
monitor is added, make_default_config() tries to create a new display
configuration by choosing a stored configuration with N-1 monitors, and then
adding a new monitor to the end of the layout. Because the stored config
doesn't match the current outputs, apply_configuration() will routinely
fail, leaving the additional display unconfigured. In this case, it's more
useful to just fall back to creating a new default configuration from
scratch so that all outputs get configured to their preferred mode.
Move logic for creating different types of configurations into separate
functions. This keeps things a bit cleaner and allows us to add alternate
configuration types more easily.
When a laptop's lid is closed we try to build and apply a temporary
configuration that disables the laptop's display if we have other
outputs.
This isn't enough though, we must also check if at least one of these
other outputs is enabled otherwise we'll try to resize the screen to
0x0 which (rightfully) hits an assertion.

It turns out that this was wrong because MetaWindow->monitor points to
the old monitor infos and they are needed to position windows in the
new configuration which happens in a monitors-changed handler.
This reverts commit e1704acda4.
The code in MetaMonitorConfig was really complex and was trying to do
way too much, using multiple different variables to determine where
things were stored, and trying to do fancy tricks to transfer
ownership.
Add a refcounting system to help simplify this, and clean up the logic.
Simply along the way, this fixes multiple bugs in the monitor config
logic, most notably bug #734889, which was my original goal to fix.
The X server sends several RRScreenChangeNotify events in a burst when
something happens which, currently, causes us to rebuild our view of
the world as many times and notify the upper layers about it which
causes a lot of bogus repeated work like rebuilding background actors.
We can avoid this extra work by looking at the timestamp in the
XRRScreenResources struct which is updated when an X client (including
us!) last changed something and comparing it with the previous
timestamp.

meta_monitor_config_match_current() only matches the number of outputs
and if the output connector, vendor, product and serial match.
In the X backend, this means that we can't use it to bypass doing any
work because it won't detect cases where we actually want to update
ourselves like e.g. an output being turned off either by us or by
another X client (e.g. xrandr).
In the native backend, unlike the xrandr backend, we only get called
on real hotplug events and thus should always trigger the common
hotplug code to (possibly) apply a new mode so the check is pointless
anyway.
https://bugzilla.gnome.org/show_bug.cgi?id=738630
In randr events, configTimestamp can be considered the hotplug time,
i.e. whenever the server notices hardware changes, this value will be
updated.
Having that in mind, we can re-work the logic to make it clearer.
There are no semantic changes.
The code here was a bit messy with the addition of
hotplug_mode_update, and the comments were a bit confusing and
inaccurate. Clean it up and comment it a bit better to make the flow and
intention more clear.
We need to tell clutter's evdev backend about the desktop's key repeat
settings so that our own key bindings event processing and
gnome-shell's chrome widgets get their fake key events for continuous
key press as they expect.
Note that the wayland frontend filters out these events and thus
wayland clients do not see them as specced.

The X server applies a default keymap to hotplugged keyboard
devices. To enforce our current settings we must re-upload the keymap
when a new keyboard shows up.
Note that setting the VCK keymap causes the server to propagate it
to all slave keyboard devices.

We overrode the property for PowerSaveMode, which meant that gdbus's
auto-generated PropertiesChanged code wasn't being run.
This really confused gnome-rr and gnome-settings-daemon's power plugin
about the current DPMS state of the display, since they used their
cached PowerSaveMode properties, and never saw a PropertiesChanged being
emitted.
If a display was on, they set it to off, and then set it back on, the
setting back on would never fire, since they thought the display was
already off.
To fix this, remove our custom property override and just respond to
notifications on the object.
Namely, this fixes the DPMS management when receiving notifications so
that it now properly times out.
Use the new DRM capabilities to figure out the correct cursor size, and
make sure that matches instead of hardcoding 64x64. This fixes incorrect
rendering on some newer AMD cards that support 256x256 cursors.

We'll need this in the wayland frontend to send a modifiers event to
clients.
Note that on X11 this isn't needed because key events include the
group index encoded in modifier state. If we ever want to make the
wayland frontend work with the X11 backend we'll handle it then.

Setting the scaling factor immediately after calling clutter_init()
avoids creating the stage at one size, then later resizing it to
a different size.

In the case of a nested Wayland compositor inside an X session,
Clutter is managing the toplevel window size, so don't call
XResizeWindow on it - this will confuse Clutter and get the size
and the hints out of sync on the toplevel window.
https://bugzilla.gnome.org/show_bug.cgi?id=736279
If we add device 2, then add device 254, then remove device 254, then
the max device ID will be 253. Scan through all the devices again on
removal to calculate a new max device ID.
Rather than have the DBus code control this, move this into
MetaBackend. This also lets us destroy idle monitors when appropriate,
rather than leaking them forever.
We indeed call this function if we're not an X11 compositor, but in this
case we're simply calling it to say that we have no cursor overlay. Make
sure not to assert fail in this case.
