That's necessary for generating Visual Studio project files that are in separate empty directories otherwise.

This will enable the script to work under Windows, which doesn't understand hashbangs interpreters.
Also built on top of #2395.

The server_host_override flag's implementation remaining
outstanding means that this only works over insecure
connections for now.

A top-level "grpc" package is added and RPC Framework
is made public.

The source code is moved from src/python to
src/python/src. A setup.py is added at
src/python. The build_python.sh and
run_python.sh scripts are updated to build
and run the Python tests by building a
package and installing it in the developer's
Python 2.7 virtual environment.

It's rather unimpressive at the moment with just
one module.

- Adds a dependency to protobuf-ruby in the gemfile
- Updates math.proto to proto3
- Updates math server and client to use protoc protos
- Updates interop server and client to use protoc protos

Also
- Fixes/Updates the noproto samples

TESTED: math_server and math_client can communicate locally.
