* Add assertions to check for OpenPGM calls with invalid parameters.

* Assertion to check that pgm_getaddrinfo is actually returning something.
 * Missing pgm_connect call.
 * Typo on TOS causing immediate abort.
 * Placeholder calls for timeouts whilst continuing spin loop functionality.
 * OpenPGM v5 now supports reference counting so remove init checks.
 * Duplicate UDP unicast port setting, requires one unicast and one multicast.
 * Incorrectly set socket rcvbuf size with sndbuf.
 * Replace std::lexicographical_compare of TSI's with long word integer comparisons.
 * pgm_socket_t::receive returns -1 on no data.
