    DEVFS - add vfs ops fhtovp, vptofh and vget
    
    * Add fhtovp and vptofh vfs ops in devfs_vfsops.c, which also fix
      an issue with coredumps. The issue was that, whenever a core
      dump should be generated of an image with a /dev/* node open,
      vptofh would return EOPNOTSUPP and hence the generated core
      would be 0 bytes.
    
    * Add helper function for fhtovp, devfs_inode_to_vnode and
      family to devfs_core.c
    
    * Also add vget vfs op, using the same mechanism as fhtovp.
