Add a "test-tool bundle-uri parse" which parses the format defined in the newly specified "bundle-uri" command. As note in the "bundle-uri" section in protocol-v2.txt we haven't specified any key-values yet, just URI lines, but we need to make sure our client doesn't die if this optional data is provided by the server. Let's add a bundle_uri_parse_line() to do that, in subsequent commits the actual client code in {connect,transport}.c will make use of it.
