add define for deprecated DNA struct members: DNA_DEPRECATED,

this means use of deprecated struct members gives a warning.

- makesdna.c preprocessor skips this.
- DNA_DEPRECATED_ALLOW is used so readfile.c can do versioning without warnings.
- this exposes some use of deprecated struct members, will deal with this after.
