    Merge branch 'LGPL-2.1+' - fix stray license claims
    
    Some files copied over wrong license headers, and two docu
    files needed actual "relicensing" by me to match the overall
    project license LGPL-2.1+.
    
    * LGPL-2.1+:
      README.md: correct license button and link to LGPL-2.1+
        Also fix the license button text and link to point to the *same* license.
      EBEAST: package.json.in: correct license field to LGPL-2.1+
      COPYING: add license text of the LGPL-2.1 to match source code license
      BSE: testobject.hh: use LGPL v2.1+ as license
        Keep the header file under the same license as the implementations.
      BSE: bseapi.idl: use LGPL v2.1+ as license
        Keep the API IDL under the same license as the implementations.
      BST: bstapi.idl: use LGPL v2.1+ as license
        The two changes by Stefan Westerfeld merged into this file predate the
        introduction of LGPL-3, and were submitted as part of a LGPL v2.1 file.
      DOCS: docextract.py: relicense as LGPL v2.1+
      DOCS: main.dox: relicense as LGPL v2.1+
