87eb6ce004 Move conn end free function callback to conn end struct, proto ctx should not keep track of such conn end details, conn end should know which function to be called to free itself, we may have different protos on different ends of the same conn

ca959ca391 Do not call topmost callback functions directly, use them in bufferevent setup only, otherwise can possibly cause double free of ctx
Run preexec and postexec logging and/or stats code when calling interface callback functions directly, they are mostly called in edge cases, but otherwise we would miss related logs and/or stats

e8e8071772 Defer conn free until the exit code of topmost callback functions, for both parent and child connections, this is necessary to handle error conditions correctly and terminate connections gracefully
So introduce term flags in ctx and replace free functions with term functions to raise the term flag, this approach enables us to terminate connection anywhere in the code without causing use after free crashes
