updatecaches: introduce a set of constants to control which are updated
Passing around a set of constant to select what need warming will be cleaner
and more flexible. We did not changed the API yet, as this changes is already
large enough. In the rest of the rest we will change more code to actually use
this constants (or more realistically pre-defined set of constant directly)
