.stop() followed directly by .reset() doesn't work. It seems asio has a
"can run" boolean variable, stop sets it to false, reset to true, so if
they are both called from inside the .run() main loop, it does nothing.

Without this it cannot use privileged port (most commonly 53) while changing
the run time user (-u).  Confirmed the fix, and okayed on jabber.

I won't update changelog for this fix because it's a regression after
the previous release.

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

Added an option to tcpSendReturnTest that makes it not send all data, resulting in a timeout

BIND 10 server. Far better suited as a unit test.
