eaf94f465c Re-apply color transforms when session is re-activated
When our session is re-activated, we need to re-apply color transforms
as the current gamma ramps might be outdated.

64ad9a61d8 Introduce ColorManager component
This change introduces a new component - ColorManager that is
responsible for color management stuff.

At the moment, it's very naive. It is useful only for updating gamma
ramps. But in the future, it will be extended with more CMS-related
features.

The ColorManager depends on lcms2 library. This is an optional
dependency. If lcms2 is not installed, the color manager won't be built.

This also fixes the issue where colord and nightcolor overwrite each
other's gamma ramps. With this change, the ColorManager will resolve the
conflict between two.
