octoclock: Avoid usage of uninitialized memory
The Octoclock host code would send uninitialized memory over the
network, which would be flagged by tools such as Valgrind. This patch
creates a factory function for OctoClock packets that initializes the
memory to zero, defaults the proto version to the OctoClock default, and
can provide a random sequence number if none is given.
