    Refactor common code in the tokenize test

commit 7f12f9a3f6aeb2452acedced5a54c66c4a19382b
Author: Przemyslaw Pawelczyk <przemyslaw@pawelczyk.it>

    Fix tokenize function and test.
    
    Previous implementation was error-prone, because allowed returning empty
    tokens (mimiced strsep()), which is fine if there is a NULL semantic.
    Unfortunately SystemTap doesn't provide it in scripts and has only blank
    string (""), therefore testing against it was misleading.
    The solution is to return only non-empty tokens (mimic strtok()).
    
    * tapset/string.stp: Fix tokenize.
    * testsuite/systemtap.string/tokenize.stp: Improve and add case with
      more than one delimiter in the delim string.
    * testsuite/systemtap.string/tokenize.exp: Ditto.
    * stapfuncs.3stap.in: Update tokenize description.
    * doc/langref.tex: Ditto.
