Tells @session that an URI from the given @hostname may be requested
shortly, and so the session can try to prepare by resolving the
domain name in advance, in order to work more quickly once the URI
is actually requested.
If @cancellable is non-%NULL, it can be used to cancel the
resolution. @callback will still be invoked in this case, with a
status of %SOUP_STATUS_CANCELLED.
