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.

Merging in multiple steps to avoid getting new tests with non-correct
plumbing.
- some more dynamic file names
- convert more commands to pure bash functions
- cleanup no longer neede files
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.
The rsyslog engine did not guard itself against output modules that do
not properly convey back the tryResume() behaviour. This then leads to
what looks like an endless loop. I consider this to be a bug of the
engine not only because it should be hardened against plugin misbehaviour,
but also because plugins may not be totally able to avoid this situation
(depending on the type of and processing done by the plugin).

Note that this adds the test case, but does not yet provide a solution
(so make check will hang when executed). Fix will be done next.
