LineArt: General code cleanups.

- Use uintxx_t for all 8/16/64 bit integer types.
- Removed prepend_edge_direct thingy which is no longer needed in current edge iterator model.
- Minor code path adjustments like only copies view vector when necessary etc.
- Correctly handle ies==NULL in edge cutting function.
- White spaces and comments etc.
