Also now permit interactivly running tests without explicitly setting
$srcdir. This now works if we are inside ./tests and fails, as before,
when we are in a different directory.

Support tools (like tcpflood) are also upgraded to support the
necessary dynamic port.s
This is part of the effort to make parallel testing possible.
We move parts of the cleanup to the buildbot cleanup, as we cannot
clean out instances on each test when we run parallel tests.
changes some of the test commands to use bash functions
includes some small bug fixes to tests where bugs were
previously not seen due to different plumbing.
note that a buffer size calculation was done wrong, but this was cosmetic
because our buffers currently all use byte size, so even though the
formula was wrong, the result was correct.
- improved testbench
- bugfix: potential data loss during file stream shutdown
- bugfix: potential problems during file stream shutdown
The shutdown/close sequence was not clean, what potentially (but
unlikely) could lead to some issues. We have not been able to describe
any fatal cases, but there was some bug potential. Sequence has now
been straighted out.
