This patch is adding an outfile parameter to the TarmacTracer
This has 3 options:
1) stdoutput = dump to standard output (default behaviour)
2) stderror = dump to standard error
3) file = dump to a file. As there is one tracer per CPU,
this means every CPU will dump its trace to a different file,
named after the tracer name (e.g. cpu0.tracer, cpu1.tracer)
It is still possible to redirect to a file with option 1 and 2
thanks to common bash redirection. What the third option is
really buying us is the capability to dump CPU traces on
separate files, and to separate the trace output from the debug-flag
output

This patch introduces the TarmacTracer: an instruction tracer which
allows to dump a gem5 execution trace in Tarmac format [1]. The new
tracer is supporting either Tarmac and TarmacV8 format specifications.
Not every traceable information has been implemented:
Implemented Trace Type:
Instruction Trace
Register Trace
Processor Memory Access Trace
Unimplemented Trace Type:
Program Flow Trace
Event Trace
Memory Bus Trace

A new InstTracer (TarmacParser) has been implemented. This tracer is
parsing a pre-existing Tarmac trace file [1] while gem5 is running; it
is comparing execution data together with trace data and it is dumping
differences.
This allows to use Tarmac format as a glue between heterogeneous
simuators speaking the same Tarmac language.
Kudos to Giacomo Gabrielli for writing the original tracer.
