trace-cmd: Start of a tracecmd swig wrapper for python

Introduce a python ctracecmd module for use in rapidly prototyping
tracing applications. The interface description is provided in
ctracecmd.i, it identifies which functions are available from within
python. A test python script is provided as tracecmd-test.py.

These bindings are expected to change significantly. Eventually I
would like to wrap this automated binding with more pythonic objects,
most likely including Trace and Event objects which merge the
functionality of tracecmd-input, pevent, record, and event structures.
This will make development of python apps much more accessible to many
application developers.

For now, this is mostly a proof of concept and is no where near
complete. It can however open a trace file and read all the events from
it, displaying them by CPU in chronological order.

V2: o Simplified interface file with SWIG ifdefs in the header files
V3: o Move attribute removal to interface file
    o Remove proxy classes and rename module to ctracecmd
    o Use the Makefile with a phony python target instead of swig.sh
