A TopicFunc is an interface to let the pubisher decide whether it needs
to send a message to a subscriber or not. It returns true if the
publisher must send the message and false otherwise.
Users of the pubsub package can create a subscriber with a topic
function by calling `pubsub.SubscribeTopic`.
Message delivery has also been modified to use concurrent channels per
subscriber. That way, topic verification and message delivery is not
o(N+M) anymore, based on the number of subscribers and topic verification
complexity.
Using pubsub topics, the API stops controlling the message delivery,
delegating that function to a topic generated with the filtering
provided by the user. The publisher sends every message to the
subscriber if there is no filter, but the api doesn't have to select
messages to return anymore.

Some users expect that the `docker top $CONT` command displays information from the inside container perspective.
They expect that the `docker top $CONT` command displays same information as the `docker exec $CONT ps -ef` command. But it does not.
That's why the `docker top` man page shall explicitly state that the `docker top $CONT` displays information from the host's point of view.

Improves the current filtering implementation complixity.
Currently, the best case is O(N) and worst case O(N^2) for key-value filtering.
In the new implementation, the best case is O(1) and worst case O(N), again for key-value filtering.

Makes it easier to debug in the future given three different docker run
executions were all outputting the same error string.

Closes#9798
@maintainers please note that this is a change to the UX. We no longer
require the -f flag on `docker tag` to move a tag from an existing image.
However, this does make us more consistent across our commands,
see https://github.com/docker/docker/issues/9798 for the history.
