Erlang RTMP library

[Max Lapshin]

Hi, at least I have extracted RTMP library from erlyvideo, it has
documentation located at  http://erlyvideo.org/rtmp/ and
repository at http://github.com/erlyvideo/erlang-rtmp/

I think, that I've found a good balance between "library is pure
functional and cannot do anything practical" and
"library keeps a lot of state inside and isn't suitable for using in
other projects".

There is a test client in examples, made from this library as a
demonstration, that it can be used not only in erlyvideo project,
but in other, for example in clients.
