- Fix default_value initialization of custom node tree interface:
This was crashing when adding a custom interface socket to a tree.
The node_socket_set_typeinfo function was called too early, creating a
default float socket, which then doesn't match the socket type after
changing to the custom type.
The node_socket_set_typeinfo only allocates and initializes
default_value when it isn't already set. That is because the function is
used either when creating new sockets or to initialize typeinfo after
loading files. So default_value has to be either null or has to be
matching the current type already.
- Fix RNA flag for string return value of the valid_socket_type callback:
String return values of registerable RNA functions need a
PROP_THICK_WRAP flag since they don't have a fixed buffer to write into.
