Subject: [PATCH] transport: provide a getter for the proxy options

As with the callbacks, third-party implementations of smart subtransports cannot
reach into the opaque struct and thus cannot know what options the user set.

Add a getter for these options to copy the proxy options into something external
implementors can use.
