Get the python scripting interface working on Windows.

This patch fixes a number of issues with embedded Python on
Windows.  In particular:

1) The script that builds the python modules was normalizing the
   case of python filenames during copies.  The module name is
   the filename, and is case-sensitive, so this was breaking code.

2) Changes the build to not attempt to link against python27.lib
   (e.g. the release library) when linking against msvcrt debug
   library.  Doing a debug build of LLDB with embedded python
   support now requires you to provide your own self-compiled
   debug version of python.

3) Don't import termios when initializing the interpreter.  This
   is part of a larger effort to remove the dependency on termios
   since it is not available on Windows.  This particular instance
   was unnecessary and unused.
