Change ptyfs to vcache.
- Use (type, minor) as key.
- Change ptyfs_allocvp to return a referenced vnode and lock where needed.
- Remove unneeded vnode backpointer ptyfs_vnode.
- Keep a single hashlist for pty nodes to make their attributes persistent.

Adapt to reality -- already open BSD style nodes do not appear on
ptyfs mounts (this changed some months ago).
- Add a map of active controlling ptys per mount and no longer abuse
  the vnode lifecycle.
- No longer set "recycle" on VOP_INACTIVE().
- Make ptyfs_used_get() private to ptyfs_subr.c
- Stop copying device attributes from traditional ptys on first allocation.
- Remove unneeded argument "lwp" from ptyfs_allocvp() and ptyfs_free_get().
OK: Christos Zoulas
