Add support for revision -> build lookup in buildbot.py and layout test result parsing

Ojan: With this added code it is now trivial to convert existing results.html files from the buildbot into the results.json files which the layout test dashboard supports.

We need to abstract out the calls to urllib2.urlopen.  We keep using the same idiom to surround them.  We could include the 404 handling and caching as optional parameters.

+ _fetch_layout_test_results

I'd prefer if all control paths had explicit returns.

+ _parse_twisted_file_row

This twisted stuff should be in a separate file.  It's not specific to buildbot.

- _longest_builder_name

Why did we get rid of this function?  It seemed helpful to document what that complex line is doing.

Ludite! :)  I think it's actually more readable to not add the "return None" since that's implied in python.

Agreed.  The functions started out as specific to this task, but I realized they could be made general.  i'm not sure where we'd put any other "twisted" stuff, but I named them so that they would be easy to recognize as general.

I had to copy the code.  I realized it was a realatively simple one-liner and didn't have any good place to put that funciton, so I just inlined it in both places.

I think I'm just gonna land as is, but I'm happy to make further changes upon further discussion with you.
