protocol-change: sets event in case of failure

[catenacyber]

Link to redmine ticket: None

Describe changes:

• Sets an event if protocol change fails (ie if there is already protocol change going on)

Another way to do this would be to set a packet's app-layer event, but AppLayerRequestProtocolChange does not have access to the current Packet and its caller FTPParseResponse does not have it neither... So, this PR implements different events for the different app-layer protocols. FTP and PGSQL do not have events yet, and are not part of this...

Are there pcaps to test this scenario? If not can you craft them?
