CPU cycle ticks. This allows the user to have CPUs of different
frequencies, and also allows frequencies and latencies that are
not evenly divisible by the CPU frequency. For now, the CPU
frequency is still set to the global frequency, but soon, we'll
hopefully make the global frequency fixed at something like 1THz
and set all other frequencies independently.

The cycles counter is based on the current cpu cycle.
cpu/base_cpu.cc:
frequency isn't the cpu parameter anymore, cycleTime is.

kern/linux/linux_system.cc:
update for changes in the way bandwidths are passed from
python to C++ to accomidate the new way that ticks works.
For now, we must get the boot cpu's frequency as a parameter
since allowing the system to have a pointer to the boot cpu would
cause a cycle.
kern/tru64/tru64_system.cc:
For now, we must get the boot cpu's frequency as a parameter
since allowing the system to have a pointer to the boot cpu would

python/m5/config.py:
Fix support for cycle_time relative latencies and frequencies.
Add support for getting a NetworkBandwidth or a MemoryBandwidth.
python/m5/objects/BaseCPU.mpy:
All CPUs now have a cycle_time. The default is the global frequency,
but it is now possible to set the global frequency to some large value
(like 1THz) and set each CPU frequency independently.
python/m5/objects/BaseCache.mpy:
python/m5/objects/Ide.mpy:
Make this a Latency parameter
python/m5/objects/BaseSystem.mpy:
We need to pass the boot CPU's frequency to the system
python/m5/objects/Ethernet.mpy:
Update parameter types to use latency and bandwidth types
python/m5/objects/Platform.mpy:
this frequency isn't needed. We get it from the clock interrupt.
python/m5/objects/Tsunami.mpy:
The clock generator should hold the frequency
sim/eventq.hh:
Need to remove this assertion because the writeback event
queue is different from the CPU's event queue which can cause
this assertion to fail.
sim/process.cc:
Fix comment.
sim/system.hh:
Struct member to hold the boot CPU's frequency.
sim/universe.cc:
remove unneeded variable.

No multiple requests to the same block outstanding from the same tester
Using false sharing, each tester only access a single byte within the block based on which tester it is

cpu/memtest/memtest.cc:
Modified to work with do_events:
No multiple requests to the same block outstanding at the same time from the same tester
Using false sharing, each tester does only 1 byte access using it's id as the blk offset
Allow for cycles before signaling deadlock, with do events it can take time to complete (NACK/blocked bus)
cpu/memtest/memtest.hh:
Updated to keep an id with each tester (used for address generation)
Updated to keep a list of outstanding address to prevent multiple outstanding per tester

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.

Don't use value() since it doesn't work with binning. If you
