Currently, the user principal path and the home set path are both hardcoded to "/", for both CalDAV and CardDAV. This poses a challenge if one wishes to run a CardDAV and CalDAV server in the same server. This commit introduces the concept of a UserPrincipalBackend. This backend must provide the path of the current user's principal URL from the given request context. The CalDAV and CardDAV backends are extended to also function as UserPrincipalBackend. In addition, they are required to supply the path of the respective home set (`calendar-home-set` and `addressbook-home-set`). The CardDAV and CalDAV servers act accordingly. The individual servers will continue to work as before (including the option of keeping everything at "/"). If one wishes to run CardDAV and CalDAV in parallel, the new `webdav.ServeUserPrincipal()` can be used as a convenience function to serve a common user principal URL for both servers. The input for this function can be easily computed by the application by getting the home set paths from the backends and using `caldav.NewCalendarHomeSet()` and `carddav.NewAddressbookHomeSet()` to create the home sets. Note that the storage backend will have to know about these paths as well. For any non-trivial use case, a storage backend should probably have access to the same UserPrincipalBackend. That is, however, an implementation detail and doesn't have to be reflected in the interfaces.
