A slew of changes based on William Fulton's code review.

- Fixed naming conventions; SwigPyBuiltin is used a lot
- Removed use of std::vector
- builtin.swg isn't included if -builtin isn't specified
- Changed many feature names to use a "python:" prefix
- Eliminated static vars in std_pair.i
- Eliminated C++-style comments (//)
- Enabled autodoc and docstring with -builtin
- Fixed non-ansi generated C code
- Detect and complain if two incompatible swig modules are loaded
- Removed argcargvtest_runme3.py, and fixed argcargvtest_runme.py
  so that 2to3 handles it better
- Removed anonymous namespaces
- Eliminated builtin_init typemaps; consolidated functionality into
  SWIG_Python_NewPointerObj
- Eliminate printf warnings from %U conversion character by switching
  to %S, which works just as well
- Fixed li_std_set_runme.py for python3, which returns set members in
  a different order from python2
