957513242c xrandr: use "hotplug_mode_update" property
Use the "hotplug_mode_update" connector property indicating that the
screen settings should be updated: get a new preferred mode on hotplug
events to handle dynamic guest resizing (where you resize the host
window and the guest resizes with it).

65db8efbe8 MonitorManager: add a KMS backend
Using the new Cogl API to actually modeset (because we can't
use the DRM API directly without controlling buffer swap), we
can finally have a KMS monitor backend, which means full display
configuration when running on bare metal.

9f64f2cf4f Rename META_POWER_SAVE_UNKNOWN to UNSUPPORTED
It conveys more clearly what this value means.

590cf4e832 MonitorXrandr: check the event timestamps before reconfiguring
If, checking the event timestamps, we see that a new configuration
was explicitly requested by an another XRandR client, don't proceed to
apply the intended configuration again, even if looking at the
EDIDs it appears that the outputs changed.
This works around some buggy Xorg drivers (qxl, vbox) that generate
a new serial number everytime the user resizes the host window.

9bd366f2a6 MonitorXrandr: skip CRTC reconfigurations that have no effect
If we're attempting to reconfigure the CRTCs to the same parameter,
skip the X call, as in some drivers a modeset can take time and
cause flicker.

5de346bfef MonitorXrandr: Fix segv when accessing possible_clones
This code requires a double pass and the segv happens later
when trying to iterate over the array.

2af20b77b6 MonitorXrandr: fix reading the current DPMS level
Add missing break statements, to avoid falling always through
to the invalid case.

909a6607c5 MonitorXrandr: try harder to get decent product/serial IDs
If the EDID does not include free-form product name and serial
number, use the numeric IDs instead, like gnome-desktop did.

015c05fbf6 MonitorXrandr: fix setting gamma ramps
The value passed to XRRCrtcSetGamma must be allocated with
XRRAllocGamma (because it relies on the locations of green and blue),
otherwise garbage is sent on the wire.

3112794d83 MonitorXrandr: update the internal data structures after applying
We were relying on the XRandR events from the X server to update
the configuration, but we were calling meta_monitor_config_update_current()
immediately after, so the MonitorConfig would be updated with the
old configuration (and we would save that to disk!)

3528b067d0 MonitorXrandr: follow the right order in applying the new configuration
First disable CRTCs that should be off in the new configuration,
then resize the framebuffer, then enable the new CRTCs.
If we don't do that, and we're making the screen smaller, X complains
with a BadMatch.

Otherwise X11 will trim the new configuration and disable outputs
outside the screen.

69467842ab MonitorXrandr: implement correct EDID parsing
To provide valid values for the vendor, product and serial fields
we need to read the EDID and parse it.
Parser kindly provided by gnome-desktop.

57077435ed MonitorManager: add EDID properties to the output DBus description
Add "edid-file", if we have one (in the KMS case, where we can point
people to the right sysfs file), or "edid" with inline data.
These are needed by colord to build the default ICC profile for
uncalibrated displays.

46de0ed462 MonitorManager: split the XRandR parts in a subclass
Instead of keeping a forest of if backend else ..., use a subclass
and virtual functions to discriminate between XRandR and the
dummy backend (which lives in the parent class togheter with the
common code)
