Subject: [PATCH 1/2] 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 2/2] 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.
