This adds vertex creasing support for OpenSubDiv for modeling, rendering, Alembic and USD I/O. For modeling, vertex creasing follows the edge creasing implementation with an operator accessible through the Vertex menu in Edit Mode, and some parameter in the properties panel. The option in the Subsurf and Multires to use edge creasing also affects vertex creasing. The vertex crease data is stored as a CustomData layer, unlike edge creases which for now are stored in `MEdge`, but will in the future also be moved to a `CustomData` layer. See comments for details on the difference in behavior for the `CD_CREASE` layer between egdes and vertices. For Cycles this adds sockets on the Mesh node to hold data about which vertices are creased (one socket for the indices, one for the weigths). Viewport rendering of vertex creasing reuses the same color scheme as for edges and creased vertices are drawn bigger than uncreased vertices. For Alembic and USD, vertex crease support follows the edge crease implementation, they are always read, but only exported if a `Subsurf` modifier is present on the Mesh.
