    sys/vfs/hammer: Add lo_to_pfs()/pfs_to_lo() macros
    
    These macros hide 16 bits shift and cast to int/uint32_t
    that are necessary on localization to/from PFS id conversion.
    
    Some code are better without details being hidden by macros,
    but this seems to be more readable with x_to_y macros that
    hide bunch of >>16, <<16, and casts.
