Nathan Binkert c0a4836077 Major improvements in the graph output code. Mostly adding more
options, making existing options more visible and dealing with
holes in data better.

util/stats/barchart.py:
    - move the options for BarChart to a base class ChartOptions so
    they can be more easily set and copied.
    - add an option to set the chart size (so you can adjust the aspect ratio)
    - don't do the add_subplot thing, use add_axes directly so we can
    affect the size of the figure itself to make room for the legend
    - make the initial array bottom floating point so we don't lose precision
    - add an option to set the limits on the y axis
    - use a figure legend instead of an axes legend so we can put the legend
    outside of the actual chart.  Also add an option to set the fontsize of
    the legend.
    - initial hack at outputting csv files
util/stats/db.py:
    don't print out an error when the run is missing from the database
    just return None, the error will be print elsewhere.
util/stats/output.py:
    - make StatOutput derive from ChartOptions so that it's easier to
    set default chart options.
    - make the various output functions (graph, display, etc.) take the
    name of the data as a parameter instead of making it a parameter to
    __init__.  This allows me to create the StatOutput object with
    generic parameters while still being able to specialize the name
    after the fact
    - add support for graph_group and graph_bars to be applied to multiple
    configuration groups.  This results in a cross product of the groups
    to be generated and used.
    - flush the html file output as we go so that we can load the file
    while graphs are still being generated.
    - make the proxy a parameter to the graph function so the proper system's
    data can be graphed
    - for any groups or bars that are completely missing, remove them from
    the graph.  This way, if we decide not to do a set of runs, there won't
    be holes in the data.
    - output eps and ps by default in addition to the png.
util/stats/profile.py:
    - clean up the data structures that are used to store the function
    profile information and try our best to avoid keeping extra data
    around that isn't used.
    - make get() return None if a job is missing so we know it was
    missing rather than the all zeroes thing.
    - make the function profile categorization stuff total up to 100%
    - Fixup the x-axis and y-axis labels.
    - fix the dot file output stuff.
util/stats/stats.py:
    support the new options stuff for StatOutput

# Graph the chart data.
# Input is a 3d matrix that describes a plot that has multiple
# groups, multiple bars in each group, and multiple values stacked
# in each bar. The underlying bar() function expects a sequence of
# bars in the same stack location and same group location, so the
# organization of the matrix is that the inner most sequence
# represents one of these bar groups, then those are grouped
# together to make one full stack of bars in each group, and then
# the outer most layer describes the groups. Here is an example
# data set and how it gets plotted as a result.
#
# e.g. data = [[[10,11,12], [13,14,15], [16,17,18], [19,20,21]],
# [[22,23,24], [25,26,27], [28,29,30], [31,32,33]]]
#
# will plot like this:
#
# 19 31 20 32 21 33
# 16 28 17 29 18 30
# 13 25 14 26 15 27
# 10 22 11 23 12 24
#
# Because this arrangement is rather conterintuitive, the rearrange
# function takes various matricies and arranges them to fit this
# profile.
#
# This code deals with one of the dimensions in the matrix being
# one wide.
