Several tweaks to make binning work in any simulation
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 --HG-- extra : convert_revision : bcb23cdb184b0abf7cecd79902f8a59b50f71fe4
