a4d7bb113a Make a new stat type of Value which is a scalar stat that
proxies for a real C/C++ scalar value or scalar functor.
This replaces the scalar() and functor() terms that were
previously used in formulas.  This helps when dumping
statistics because the formulas are not supposed to change.

cpu/base_cpu.cc:
    Add a number of cycles stat to the cpu object that tracks the
    number of cycles that the cpu has executed.  This starts to pave
    the way for cpu cycles being different from event ticks.
cpu/base_cpu.hh:
    provide a functor for calculating all simulated instructions
    of all CPUs and a virtual function for determining that number.
    To deal with the change from functor() to Value::functor()
cpu/simple_cpu/simple_cpu.cc:
    simTicks -> numCycles
    numInsts is now a real Scalar stat, not a Formula
cpu/simple_cpu/simple_cpu.hh:
    numInsts is now a real Scalar stat, not a Formula
    count all instructions
sim/stat_control.cc:
    simInsts, simTicks, hostMemory, and hostSeconds are no
    longer Statistics::Formula but rather Statistics::Value
    add new stat for tick frequency
sim/stats.hh:
    don't need everything to be extern.
test/Makefile:
    Make stuff work a tad bit better
test/stattest.cc:
    test out Statistics::Value

25a358983a Major stats package cleanup
Add support for generic visitors for stats and use them
to implement independent output functions.

Support for mysql output and some initial code for hacking
on mysql output with python

sim/system.hh:
    update for changes in stats package
base/statistics.cc:
    move the python output code to base/stats/puthon.(cc|hh)
    and reimplement it as a visitor.

    move the text output code to base/stats/text.(cc|hh) and
    reimplement it as a visitor.

    move the database stuff into base/stats/statdb.(cc|hh) and
    get rid of the class.  Put everything as globals in the
    Statistics::Database namespace.

    allocate unique ids for all stats.

    directly implement the check routine and get rid of the
    various dumping routines since they're now in separate files.

    make sure that no two stats have the same name

    clean up some loops
base/statistics.hh:
    major changes to the statistics package again

    lots of code was factored out of statistics.hh into several
    separate files in base/stats/ (this will continue)

    There are now two Stat package types Result and Counter that
    are specified to allow the user to keep the counted type
    separate from the result type.  They are currently both doubles
    but that's an experiment.  There is no more per stat ability to
    set the type.  Statistics::Counter is not the same as Counter!

    Implement a visitor for statistics output so that new output
    types can be implemented independently from the stats package
    itself.

    Add a unique id to each stat so that it can be used to keep
    track of stats more simply.  This number can also be used in
    debugging problems with stats.

    Tweak the bucket size stuff a bit to make it work better.

    fixed VectorDist size bug
cpu/memtest/memtest.cc:
    Fix up for changes in stats package
    Don't use value() since it doesn't work with binning.  If you
    want a number as a stat, and to use it in the program itself,
    you really want two separate variables, one that's a stat,
    and one that's not.
cpu/memtest/memtest.hh:
    Fix up for changes in stats package
test/Makefile:
    Try to build stuff now that directories matter
test/stattest.cc:
    test all new output types
    choose which one with command line options
