[Nice] Request for review: MS-TURN TCP transport support

[Jakub Adam]

Hi,

I developed a series of libnice patches that enable TCP connection with MS Lync
media relay servers according to [1], with the initial purpose to enhance A/V
capabilities of Pidgin Sipe plugin[2].

Now I'd like to contribute this code to libnice and kindly ask for its review first.
You can fetch it from [3], the actual patches are in branch ms-turn-tcp.
