RNA: Commit of the API patch by vekoon. This adds Functions to RNA,

which can be defined to call C functions with defined parameters.

* Parameters are RNA properties, with the same types.
* Parameters are stored in a ParameterList, which is like a small
  stack with the values. This is then used to call the C function.
* Includes Python integration.

* Only one test function is part of this commit, ID.rename.
* Integration with the editors/ module is not included in this
  commit, there's some issues to be worked out for that still.
