10.3.1.2. [Minor] Incorrect data fragmentation of discovery messages for DomainParticipant built-in topic

Connext Micro incorrectly fragmented DomainParticipant discovery messages if the Maximum Transmission Unit (MTU) was set to a value lower than the DomainParticipant built-in data. Fragmentation of the DomainParticipant built-in topic is not supported. The system now ensures that the creation of a DomainParticipant will fail if the minimum MTU across all transports used for discovery is less than the size of the DomainParticipant discovery message.
