Merge branch 'tc/bundle-uri-empty-fix' into next

The client-side parser of server-advertised bundle-URI list has been updated to drain the remaining response in order to avoid protocol desynchronization when the server sends a misconfigured list. Also, the server-side has been taught to omit empty configuration values instead of sending invalid key-value lines. * tc/bundle-uri-empty-fix: bundle-uri: stop sending invalid bundle configuration bundle-uri: drain remaining response on invalid bundle-uri lines
