fixed order of emit(packet) / send(packet)
OSPF bugfix: msg pointer was used after send(msg)
sctp: bugfix: sctpmsg was used after send

chunk->getChunkType() get data from sctpmsg
dhcp server: delete timer from timerlist before process packet, unknown timer throws an error
dhcp server: local variable renamed
dhcp server: optimization: packets stored in timers as controlinfo instead of msgpar -- fingerprint5 changed

omnetpp 5.0 fingerprint calculated with the controlinfo
pingapps: should use emit() before send()
