Merge pull request #188 from csoler/v0.6-SecuredTunnelService
V0.6 secured tunnel service. Please reports bugs to me (I have tested with valgrind and as many configurations as possible, but the multi-service gathering into GXS tunnels shared for each GXS id pair is not a totally simple thing, so I expect to have missed a few issues).
