Manuel Pégourié-Gonnard 568f1e7cb3 Merge branch 'iotssl-515-max-pathlen' into development 
* iotssl-515-max-pathlen:
  Add Changelog entries for this branch
  Fix a style issue
  Fix whitespace at EOL issues
  Use symbolic constants in test data
  Fixed pathlen contraint enforcement.
  Additional corner cases for testing pathlen constrains. Just in case.
  Added test case for pathlen constrains in intermediate certificates
