Handle the following situations in a URL (e.g. in SRC_URI):
* Trailing semicolon in a URL - this is now ignored.
* Parameter specified with no value (no equals sign). This still
produces an error, but at least it is MalformedUrl with a proper
message rather than "ValueError: need more than 1 value to unpack".
