import tmpfs code, originally from netbsd.

heavy lifting by Pedro Martelletto, timestamp fixes by me.

THIS IS NOT ENABLED YET, AND REQUIRES UVM CHANGES AND REVIEW.
Imported, so that working on it can be mostly done in tree with less painful
diff exchanges, and that we have history of further changes.

okay tedu@, deraadt@
