This control extension is enabled by default and works with existing
do_search handlers .

Matching rules objectIdentifierMatch and objectIdentifierFirstComponentMatch
now behave correctly when comparing a numeric OID and the corresponding short
descriptive name or two different short descriptive name belonging to the
same OID.

DN handling now fully conforms to RFC4514 and has a high test coverage.
Still lacks a lot of documentation.

While "src/" seems to be the recommended way, too many (linter/testing/...)
tools have problems with it.
