RNA: C API

* RNA_blender.h is now generated along with the other files. It is not
  used anywhere yet, and still located quite hidden next to the other
  rna_*_gen.c files. Read only access for now.
* Inherited properties are not copied from the base anymore but
  iterated over. Patch by Vekoon, thanks!
* Array get/set callbacks now do the whole array instead of getting an
  index. This is needed for some layers for example so python can set
  the array as a whole, otherwise the check that one layer has to be
  enabled at all times gets in the way. Also nicer for the C API.
* Also some changes to returning pointers to make the API cleaner, got
  rid of the type() callback and instead let get() return PointerRNA
  with the type included.

The C API looks like this currently:
