in repository gnunet.

commit 5be14856a356b087ad97b479efd9b06172fdfd2f
Author: Andreas Ebner <address@hidden>
AuthorDate: Sat Sep 14 16:58:39 2019 +0200

    Bugfixes, changed test reporting behavior, modified intermediate result 
reporting:
    
    - fixed a memory error when serializing the delegations
    - all tests now handle the returned error code from the gnunet-credential.c 
via "ret" variable
    - intermediate reporting excluded during collect message
    - intermediate reporting now contains the direction (bw/fw)
