With the additional commands and timestamps added to the tool, the default
case (-t) has been broken. Now that the allocation timestamps are saved
outside of the txt field, allow us to properly sort the data by number of
times the record has been seen. Furthermore prevent the misuse of the
commandline arguments so only one compare option can be used.

With the introduction of allocation timestamps being included in
page_owner output, each record becomes unique due to the timestamp
nanosecond granularity. Remove the check in add_list that tries to
collate each record during processing as the memcmp() is just additional
overhead at this point.
Also keep the allocation timestamps, but allow collation to occur without
consideration of the allocation timestamp except in the case were
allocation timestamps are requested by the user (the -a option).
