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
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.
imfile: Initial implementation of solaris FEN API (without wildcards)
FEN API is used to implement simular event based file
monitoring like with inotify.
This commit provides partial functionality. It supports event-driven
processing of files but does not yet provide wildcard functionality.
Wildscards will be provided by a later commit.
This can be committed as-is because the previous code did also
not provide wildcard support, so this is an improvement for
Solaris in any case.

some tests had invalid use of the testbench exit functions (should not
be called on error to preserve error state) and also did do some
invalid variable references.
