IPC Pingpong!

This example is to illustrate the usage of RIOTs IPC messaging system.

The application starts a second thread (in addition to the main thread) and sends messages between these two threads. The main thread call thread_send_receive() in an endless loop. The second thread receives the message, prints 2nd: got msg from x to stdout and sends a reply message with an incrementing number back to the main thread.

The correct output should look like this:

kernel_init(): This is RIOT! (Version: xxx)
kernel_init(): jumping into first task...
Hello world!
second_thread starting.
2nd: got msg from 1
Got msg with content 2
2nd: got msg from 1
