With the number of accessed memory addresses and the duration of the
trace, we can deduce the size of the rectangular memory fault space.
This will be used in testing.
This change makes all C++-based tools in tools/ abort when they
encounter an unknown commandline parameter (both option or
non-option). This has already caused some confusion, as in some cases
unexpected behaviour can be the result. For example, "prune-trace -t
mytrace.tc -d database" up to now ignored the "-t" parameter, took
"mytrace.tc" as the first non-option parameter (and ignored it); as no
option parameter may follow the non-option parameters, all other
options were ignored as well.

The input (taken on stdin) is a gem5.opt --debug-flags=MemoryAccess
trace (--format gem5), or a dump-trace output (--format dump) for easy
trace synthesis (for testing purposes).
gem5 format: Currently imports physical, not virtual memory addresses.
dump format: Currently ignores extended trace information.

The new parameter -s/--stats shows trace statistics such as number of
instructions, number of memory reads/writes, and duration in simulator
time.

TODO: Showing timing or extended trace information should be configurable
with a commandline switch later.
