There was a rare possibility that the E_AGAIN/E_INTERRUPT handling
could cause an infinite loop (100% CPU Usage), for example when a TLS
handshake is interrupted at a certain stage.
- After gnutls_record_recv is called, and E_AGAIN/E_INTERRUPT error
occurs, we need to do additional read/write direction handling
with gnutls_record_get_direction.
- After the second call of gnutls_record_recv (Expand buffer)
we needed to also check the eror codes for E_AGAIN/E_INTERRUPT
to do propper errorhandling.
- Add extra debug output based on ossl driver.
- Potential fix for 100% CPU Loop Receiveloop after gtlsRecordRecv
in doRetry call.

when tcpflood detected a certificate error, it reported an
error message but did not abort. This could make errors undetectable
during CI runs.
also fix tests which did not properly provide CA cert (which than
caused the error).
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.

This is required to support parallel test runs.
Among others, make thise files dynamic:
* test-spool
* rsyslog.input
* rsyslog.out*.log
* tmp.in
Also:
* convert presort test statement to function
* cleanup imfile truncation test
* cleanup imfile-growing-file-id test
some cruft was left due to copy and paste error
* serialize mysql tests
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.
