[TASK] Remove static method variables

Static method variables are even more pita than static class
variables, especially if their state is created from db rows
or path information: It is nearly impossible to get rid of
this state at a later point again, even reflection does not
help here.

The patch abandons all 'static $foo' method variables from
the system, using these strategies:

* Remove some entirely which were used as first level cache
  and only cache-away simple non db related code structures.
* Switch some to use cache framework cache_runtime instead
  which can be evicted easily.
* Use class properties in some cases instead.
