Organize the usage options alphabetically and improve the description of
some options. Also separate the more complicated cull options from the
single use compare options.

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).

With the removal of free timestamps from page_owner output, we no longer
need to handle this case or the "unreleased" case. Remove all references
to both cases.

When using cull option with 'tg' flag, the fprintf is using pid instead
of tgid. It should use tgid instead.

Rename tools/vm to tools/mm for being more consistent with the code and
documentation directories, and won't be confused with virtual machines.
