There is no reason for it to be public now, it is no longer possible to build an
event
without using the helpers.
This also allows us to delay setting the time until after the nil exporter
check, for
a significant time saving in the no exporter case.

This separates the concerns of tag collections that have to be iterated
and tag collections that need lookup by key.
Also make it so that events just carry a plain slice of tags.
We pass a TagMap down through the exporters and allow it to be
extended on the way.
We no longer need the event.Query method (or the event type)
We now exclusivley use Key as the identity, and no longer have a
common core implementation but just implement it directly in each
type.
This removes some confusion that was causing the same key through
different paths to end up with a different identity.

This allows us to hide the implementation details of how tags are stored on a
context from the normal interface, to allow us to explore more efficient
mechanisms.
The current storage is not intended as the most efficient choice, this cl is
about isolating the API so we can experiment with benchmarks in the future.

This is now the only package that is exposed to normal use, and should
be the only thing to appear in libraries.
