`app.driver.List` on `"/"` is very expensive if registry contains significant amount of images. And the result isn't used anyways.
In most (if not all) storage drivers, `Stat` has a cheaper implementation, so use it instead to achieve the same goal.

Release notes for forwarded header fix patch release

Signed-off-by: Derek McGowan <derek@mcgstyle.net> (github: dmcgowan)

Partially reverts change adding support for X-Forwarded-Port.
Changes the logic to prefer the standard Forwarded header over
X-Forwarded headers. Prefer forwarded "host" over "for" since
"for" represents the client and not the client's request.

Add trim name method helper to create name only references

Add a simple helper to create name only references without having
to first get the name as a string and reparse. This method does
not fail so ignoring or checking error to simply trim reference
is not required.
