Whether a mode is interlaced or not is now exported by adding a
'is-interlaced' (b) value to the mode properties variant. Implement the
is_interlaced() vfunc using this information.
The mode format communicated via the new D-Bus API changed to
specifying modes using a per monitor unique mode ID string. The uint
'flags' was also changed to more flexible a{sv} 'properties' structure.
This adapts as much as possible mutter's new display config API to the
current display panel's expectations. In particular we keep the
concept of logical monitors hidden from the panel. They will later be
exposed when we re-design the panel to make full use of the new API.
