    Modified shell getsplits command to match against obscured extents (#5983)
    
    This commit modifies the shell getsplits command to optionally
    accept 1 or more arguments to the `-v` option. When supplied, the
    getsplits command will only print information for the splits where
    the value in the first column (the obfuscated extent information)
    matches one of the supplied arguments. Example invocation:
    
      getsplits -t <table> -v <extent1> <extent2> ...
    
    Closes #5970
