code cleanup/bugfix uninitialized values

- edgebisect bmesh operator used uninialized beauty field.
- BLI_join_dirfile could read from before the string bounds when passed an empty dir string.
- pransform could use an uninitialized projected coordinate (unlikely but possible)
- RNA_property_path_from_ID_check would compare against an uninitialized pointer when the path wasn't found.

also have bmesh walker use BM_edge_other_vert() utility function.
