REST API limited to 30 responses

[jacob-keller]

The current implementation of the REST API doesn't handle pagination responses for listing patches, so it is limited to a single reply, which is 30 items by default on most patchwork servers.

Supporting pagination looks like it requires parsing the Link header response and properly iterating through the pages. I don't think urllib supports handling Link headers, but the requests library could be used instead of urllib and that includes built-in support for at least parsing Link headers which would make this easier to implement.
