configuration so that we can always have binning on.
base/statistics.cc:
If we're binning, and there is no bin active at the time
we check all stats stuff, create a bin.
base/statistics.hh:
FS_MEASURE doesn't exist anymore
base/stats/text.cc:
don't print out bin names if there is only one bin
sim/process.cc:
don't zero stats. It happens automatically.
Don't activate the context at the time it is registered,
instead activate the first context in a startup callback.
sim/process.hh:
Add startup callback to initialize the first exec context
