Update redis vocabulary to use the modern protocol

The existing Redis vocabulary was using a very old and outdated version of the
Redis protocol that couldn't even write values to a modern Redis install.  This
patch updates the library and tests to use the newer protocol, which should
also work on Redis servers all the way back to Redis 1.2.

Windows runs ctrl-c in its own thread and doesn't by itself interrupt
blocking system calls when it is pressed. Therefore you have to manually
send an interrupt signal to the stuck thread.
