introduce convert-trace tool

Browse Source 
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.
