memory model. These changes really should have been part of the
previous changeset.
SConscript:
Move System and PhysicalMemory sources from being full_system_sources
to base_sources, since they are now used in syscall emulation also.
Also add source files for PageTable and ProxyMemory objects.
Actual source files for PhysicalMemory and ProxyMemory are not committed
yet since they still need to be ported from old interface.

System object now exists for both fullsys and syscall emulation, as the
latter needs it so that Process objects can find the shared PhysicalMemory
for initialization.
Changes are incomplete: still need to fix up Process (& EioProcess) memory
initialization and syscall emulation code for new mem interface.

Key thing needed for syscall emulation at this point is
the PhysicalMemory object (for Process initialization).

dev/sinic.cc:
Virtualize sinic
- The io registers are replicated many times in memory, allowing the NIC to
differentiate among several virtual interfaces.
- On the TX side, this allows multiple CPUs to initiate transmits at the same
time without locking in the software. If a partial packet is transmitted,
then the state machine blocks waiting for that virtual interface to complete
its packet. Then the state machine will move on to the next virtual
interface. The commands are kept in fifo order.
- On the RX side, multiple partial transmits can be simultaneously done.
Though a packet does not deallocate its fifo space until all preceeding
packets in the fifo are deallocated. To enable multiple receives, it
is necessary for each virtual nic to keep its own information about its
progress through the state machine.
dev/sinic.hh:
Virtualize sinic
Receive state must be virtualized since we allow the receipt of packets in
parallel.

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:
