Updated to pybench 2.0.

Browse source 
See svn.python.org/external/pybench-2.0 for the original import of that
version.

Note that platform.py was not copied over from pybench-2.0 since
it is already part of Python 2.5.

It is usually a good idea to run pybench.py multiple times to see
whether the environment, timers and benchmark run-times are suitable
for doing benchmark tests.
You can use the comparison feature of pybench.py ('pybench.py -c
<file>') to check how well the system behaves in comparison to a
reference run.
If the differences are well below 10% for each test, then you have a
system that is good for doing benchmark testings. Of you get random
differences of more than 10% or significant differences between the
values for minimum and average time, then you likely have some
background processes running which cause the readings to become
inconsistent. Examples include: web-browsers, email clients, RSS
readers, music players, backup programs, etc.
If you are only interested in a few tests of the whole suite, you can
use the filtering option, e.g. 'pybench.py -t string' will only
run/show the tests that have 'string' in their name.

Version History
---------------
2.0: rewrote parts of pybench which resulted in more repeatable
timings:
- made timer a parameter
- changed the platform default timer to use high-resolution
timers rather than process timers (which have a much lower
resolution)
- added option to select timer
- added process time timer (using systimes.py)
- changed to use min() as timing estimator (average
is still taken as well to provide an idea of the difference)
- garbage collection is turned off per default
- sys check interval is set to the highest possible value
- calibration is now a separate step and done using
a different strategy that allows measuring the test
overhead more accurately
- modified the tests to each give a run-time of between
100-200ms using warp 10
- changed default warp factor to 10 (from 20)
- compared results with timeit.py and confirmed measurements
- bumped all test versions to 2.0
- updated platform.py to the latest version
- changed the output format a bit to make it look
nicer
- refactored the APIs somewhat
1.3+: Steve Holden added the NewInstances test and the filtering
option during the NeedForSpeed sprint; this also triggered a long
discussion on how to improve benchmark timing and finally
resulted in the release of 2.0
1.3: initial checkin into the Python SVN repository
