Simplify interfaces between ChannelMessageHandler and PeerManager,
by switching all ChannelMessageHandler errors to HandleError sent
internally instead of being return. With further refactors in Router
and PeerChannelEncryptor, errors management on the PeerManager-side
won't be splitted between try_potential_handleerror and HandleError
processing.

Inside ChannelManager, we now log MsgHandleErrInternal and send
ErrorAction to PeerManager.

On a high-level, it should allow client using API to be more flexible
by polling events instead of waiting function call returns.

We also update handle_error macro to take channel_state_lock from
caller which should avoid some deadlock potential for some edges
cases.

Filter out IgnoreError in handle_error macro, update test in
consequence.
