    usr.sbin/makefs/hammer2: Introduce XOP fifo realloc
    
    Since makefs HAMMER2 used a serialized single threaded xops,
    it was not possible to have more than HAMMER2_XOPFIFO fifo entries.
    
    Change this to realloc XOP fifo whenever it hits current limit.
    This is also what Free|Net|OpenBSD HAMMER2 currently do until they
    support multi-threaded xops.
    
    This makes possible to support VOP_READDIR, and that makes possible
    to support recursive read for "-o R" option.
