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
This is work torward the ability to run the testbench in parallel.
Some small issues in tests have also been detected, which were not
previously seen. They have been fixed. We did not do separate
commits for this as it would clutter the commit log with not
really relevant info.
Also move some cleanup to "make clean" target
To support parallel testbench runs, we need to have dynamic work files.
So deleting work files on each test does not work, especially as we can
no longer assume they are "left-overs" from a failed test - they may
actually (and quite likely) belong to tests that run in parallel.
So the proper solution is to do via "make clean".

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.
This commit greatly refactors imfile internal workings. It changes the
handling of inotify, FEN, and polling modes. Mostly unchanged is the
processing of the way a file is read and state files are kept.
This is about a 50% rewrite of the module.
Polling, inotify, and FEN modes now use greatly unified code. Some
differences still exists and may be changed with further commits. The
internal handling of wildcards and file detection has been completely
re-written from scratch. For example, previously when multi-level
wildcards were used these were not reliably detected. The code also
now provides much of the same functionality in all modes, most importantly
wildcards are now also supported in polling mode.
The refactoring sets ground for further enhancements and smaller
refactorings. This commit provides the same feature set that imfile
had previously and all existing CI tests pass, as do some newly
created tests.
Some specific changes:
- bugfix: module parameter "sortfiles" ignored
This parameter only works in Solaris FEN mode, but is otherwise
ignored. Most importantly it is ignored under Linux.
fixes https://github.com/rsyslog/rsyslog/issues/2528
- bugfix: imfile did not pick up all files when not present
at startup
fixes https://github.com/rsyslog/rsyslog/issues/2241
fixes https://github.com/rsyslog/rsyslog/issues/2230
fixes https://github.com/rsyslog/rsyslog/issues/2354
- bugfix: directories only support "*" wildcard, no others
fixes https://github.com/rsyslog/rsyslog/issues/2303
- bugfix: parameter "sortfiles" did only work in FEN mode
fixes https://github.com/rsyslog/rsyslog/issues/2528
- provides the ability to dynamically add and remove files via
multi-level wildcards
see also https://github.com/rsyslog/rsyslog/issues/1280
- the state file name currently has been changed to inode number
This will further be worked on in upcoming PRs
see also https://github.com/rsyslog/rsyslog/issues/2231
- some enhancements were also done to CI tests, most importantly
they were made more compatibile with BSD
Note that most of the mentioned bug fixes cannot be applied to older
versions, as they fix design issues which are solved by the refactoring.
Thus there are not separate commits for them.
Distro maintainers: you need to decide to apply this patch as whole
or not. Believe me, it is not worth the effort to try to extract
specific patches from this commit. There is a good reason we do
not have multiple commits.

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.
