Luca Boccassi bdc676f687 Problem: REP leaves label msgs for dead REQ in pipe
Solution: roll back the pipe if writing messages other than the
first fails in router::xsend. Roll it back also when the pipe is
terminating.
Also add test case that reproduces the memory leak when ran with
valgrind.
Fixes #2567
