Adds a "-pad" function to the memory_breakdown tool. When run with no arguments, memory_breakdown periodically prints a single line to stdout containing memory data for the host and all currently active domains. When run with '-pad <file>', where <file> contains the data output from a previous run, memory_breakdown inserts extra padding values so that all lines in the output have the same number of columns.
