Expected behavior

**Env

Describe the bug

/usr/share/icinga2/include/command-plugins.conf provides the http CheckCommand. Since version 2.3.0 there is a new option in check_http which allows for checking the correctness of a certificate and hostname match: --verify-host. Please add this to the built in template library.

Description of the problem

During the work of #3393 and #3381 we found the regex related test cases (https://github.com/syslog-ng/syslog-ng/blob/master/lib/filter/tests/test_filters_regexp.c) insufficient.

Proposed solution

• Overview the current test cases. (i.e. Peter's founding in #3393, where we blindly accepted the reported length.)
• Introduce new test cases for dupnames. (#3381)

I would like to be able to search multiple indices. I suggest the search function is extended so that the index parameter can be an array.
