Introduce layer library in genfs. This set of files abstracts most of the functionality of nullfs. The latter is now just a mount & unmount routine, and a few tables. umapfs borrow most of this infrastructure. Both fs's are now nfs-exportable. All layered fs's share a common format to private mount & private vnode structs (which a particular fs can extend). Also add genfs_noerr_rele(), a vnode op which will vrele/vput operand vnodes appropriately.

Add a set of generic file system operations that most file systems use. Also, fix some time stamp bogosities.

Add support for fcntl(2) to generate VOP_FCNTL calls. Any fcntl call with F_FSCTL set and F_SETFL calls generate calls to a new fileop fo_fcntl. Add genfs_fcntl() and soo_fcntl() which return 0 for F_SETFL and EOPNOTSUPP otherwise. Have all leaf filesystems use genfs_fcntl(). Reviewed by: thorpej Tested by: wrstuden
