remove @access and unnecessary $name
Merge pull request #1408 from dereuromark/master-cleanup

remove @access and unnecessary $name
Introduce the `strip` argument to Router.

This allows callers to request that the basepath *not* be stripped off
when normalizing string URL's. This is important in AuthComponent when
handling redirect URL's as the redirect location could point to
a controller that shares a name with the base path.

Refs #3897
Refs #3916
Update AuthComponent to not strip when normalizing URLs.

Revert most of the changes done to fix #3897 originally and try
a different strategy of solving the base path issues and not breaking
apps running in a subdirectory.

Fixes #3916
Revert previous changes.

Adding this parameter was a mistake. Remove it.
Rebalance where URL normalization happens in AuthComponent.

Make URL's not include the base path when storing them in the session.
This makes future redirection simpler. When URL's are an array use
Router::url() on them.

Fixes #3916
