#2781: Add python exception info extractor

Comment(by sohail-boost-trac@…):

 For me, it would be most useful if I could register an exception handling
 callback which allows me to throw my own exception when an error occurs in
 Python. This way, Python code can be called from C++ code just as if it is
 C++ code. Otherwise, we need to have boilerplate try/catch.

 For example, I'd like to write:
 void my_from_python_exception_handler()
   throw MyException(pyerror_exctract<My::String>()); // don't hardcode
 above extract to std::string

 void somewhere_else_in_the_app()

 Hope that helps.
