RNA

Implementation of RNA side of foreach_get/foreach_set,
Campbell will do python code.

Three functions for efficiently setting some property for all
items in a collection. RNA_property_collection_raw_array gives
access to the properties as an array with length, stride, and
type specified, if this is possible, i.e. not when it uses a
ListBase, or if a manual get/set function is implemented.

Two other functions take a C array pointer and get/set it
using the a collection + property name, using efficient array
access if possible, and otherwise using slower RNA iterator.

RNA_property_collection_raw_get
RNA_property_collection_raw_set

The number of type conversion required here got a bit out of
hand, it could be more efficient still if checking for more
cases, but function is already long enough.
