The str.rpartition() function is related to str.split() and is used for
splitting strings. It was introduced in Python 2.5 and therefore cannot
be used in tracetool as Python 2.4 compatibility is required.
Replace the code using str.rsplit().

In Python 2.5 keyword arguments were added to __import__(). Avoid using
them to achieve Python 2.4 compatibility.

The tracetool script is written in shell and has hit several portability
problems due to shell quirks or external tools across host platforms.
Additionally the amount of string processing and lack of real data
structures makes it tough to implement code generator backends for
tracers that are more complex.
This patch replaces the shell version of tracetool with a Python
version. The new tracetool design is:
scripts/tracetool.py - top-level script
scripts/tracetool/backend/ - tracer backends live here (simple, ust)
scripts/tracetool/format/ - output formats live here (.c, .h)
There is common code for trace-events definition parsing so that
backends can focus on generating code rather than parsing input.
Support for all existing backends (nop, stderr, simple, ust,
and dtrace) is added back in follow-up patches.
