      Bug#28563 Test suite "jp" fails completely
    - The main goal of this fix is to make the "jp" suite runnable in general
      and to make it more robust for use in pushbuild under build team conditions.
    - It was decided to fix the remaining heavy issues within the
      architecture of this test later
      (-> WL 4327 Redesign the 'jp' testsuite for build team testing conditions)
      Only the test jp_trim_sjis got some significant improvements of its
      architecture (Just as proof of concept for the other tests).
    - Tests suffering from
         Bug 36597 Testsuite "jp": Suspicious results for some tests
                   (unexpected result sets)
      were disabled
    - *.opt files were used to avoid differences on OS (Windows) because of
      case sensitive tablenames within the tests
