Description:

Add MS-TURN TCP support

The old TCP support never worked. Older versions of farstream defined
FS_NETWORK_PROTOCOL_TCP but there were even *tests* to ensure that any
attempt to use it would result in FS_ERROR_INVALID_ARGUMENTS.

This adds the three variants of TCP support that are now supported in
farstream 0.2.6 onwards, and bumps the requirement in configure.ac
accordingly.

Olivier says the Google ones should probably be passive. Since they
never worked anyway, I'm not going to lose too much sleep over them.

[dwmw2: reworked to remain compatible with the farstream 0.1 build]
