- need stdlib.h for random()
- need return even after assert()
- cppcheck mentioned a few args that could be passed by reference

Conflicts:

Was not NetBSD-specific, but the symptom only appeared to show there; you cannot reliably do 2 tcp async_send's without waiting for the completion in between.

Fixed it by writing output to a temporary buffer that includes the TCP length data (we might want to consider allowing MessageRenderer to append to a buffer, btw)

They need to be put to the test file, if they are not default values of
parameters.

It seems g++ doesn't like to pass objects defined inside a function as a
template parameter somewhere. Taken out of the function.

* A variable name
* Clarification of man pages

Handled conflict.
Also removed spaces on a blank line.

Also manually fixed some conflicts.

Also sort these.
