Subject: [PATCH 1/9] monitor-manager-xrandr: Work around spurious hotplugs on
Xvnc
Xvnc turns its outputs off/on on every mode set which makes us believe
there was an hotplug when there actually wasn't. Work around this by
requiring new randr configuration timestamps to be ahead of the last
set timestamp by at least 100 ms for us to consider them an actual
hotplug.

Subject: [PATCH 2/9] monitor-manager-xrandr: Force an update when resuming
from suspend
The stack below us isn't as reliable as we'd like and in some cases
doesn't generate RRScreenChangeNotify events when e.g. resuming a
laptop on a dock, meaning that we'd miss newly attached outputs.

Subject: [PATCH 4/9] monitor-manager: Consider external layout before default
linear config
In case of no existing configuration, we use a default layout of
aligning attached displays horizontally. This sidesteps any layout
configuration that is done externally, for instance via xorg.conf,
which is not desirable. Instead, base the initial configuration on
the existing layout if it passes some sanity checks before falling
back to the default linear config.

Subject: [PATCH 5/9] monitor-manager: only reuse initial-config if monitor
topology matches startup
Right now we try to apply the current monitor config when a new
monitor is attached. The current config obviously doesn't include the
new monitor, so the new monitor isn't lit up.
The only reason we apply the current config at all is to handle the
startup case: We want to reuse the config set in Xorg when first
logging in.
This commit changes the code to look at the *initial config* instead
of the current config, and only if the new monitor topology matches
the start up topology.

Subject: [PATCH 6/9] monitor-config-manager: Use current mode when deriving
current config
Instead of overriding the existing mode with the preferred mode of the monitor,
use the one already configured. Also use the MetaMonitor API for deriving the
position of the monitor in the screen coordinate space.

Subject: [PATCH 7/9] monitor-manager: Don't try to derive current config on
non-X11
This commit also reworks the initial config state reading some. Appart from
avoiding trying to inherit from backends where it doesn't make sense, it does
the following changes:
* Replace the name "initial" with "inherited", as the initial config in the
context of monitor management is the one used initialization. E.g. if there is
a applicable configuration in monitors.xml, the initial config is taken from
there.
* Don't make "_create_()" functions have side effects. Previously
meta_monitor_config_manager_create_initial() also set state on the config
manager object. Instead, add a meta_monitor_config_manager_ensure_inherited()
and meta_monitor_manager_get_inherited_config() function to make things more
explicit.
* Don't recreate "is-applicable" logic, just use the existing helper.

Subject: [PATCH 9/9] monitor-manager/xrandr: Create dummy screen sized monitor
if no RANDR
When there is no RANDR support enabled in the X server, we wont get
notified of any monitors, resulting in mutter believing we're being
headless. To get at least something working, although with no way
configuration ability, lets pretend the whole screen is just a single
monitor with a single output, crtc and mode.
