  During review and verification of the patch created by Sarosh Arif:
"test_distributor: prevent memory leakages from the pool" I found out
that running distributor unit tests multiple times in a row causes fails.
So I investigated all the issues I found.

There are few synchronization issues that might cause deadlocks
or corrupted data. They are fixed with this set of patches for both tests
and librte_distributor library.

* assign NULL to freed mbufs in distributor test
* fix handshake check on legacy single distributor
* add patch 7 passing NULL to legacy API calls if no bufs are returned
* add patch 8 fixing API documentation

Lukasz Wojciechowski (8):
  app/test: fix deadlock in distributor test
  app/test: synchronize statistics between lcores
  app/test: fix freeing mbufs in distributor tests
  app/test: collect return mbufs in distributor test
  distributor: fix missing handshake synchronization
  distributor: fix handshake deadlock
  distributor: do not use oldpkt when not needed
  distributor: align API documentation with code
