    sbin/hammer2/cmd_debug.c: Refactor unreadable cmd_show()
    
    0b7381572b131c74051832dc251604e7f77b5a54 added multi-volumes
    support to cmd_show() (entry point of freemap,show,volhdr directives)
    with minimum modification using goto, but the code has been not
    so readable since then. Rewrite this entry point function.
    
    The output is same except that "Volume %d header %d..."
    by default (= when not showing volhdr or bref for all volumes)
    appears before printing each volhdr or bref, rather than all
    at once in the beginning.
