A bunch of fixes so that site.py works

[isaiah]

This is the all in one PR that includes changes in all previous PRs, if it doesn't make sense, I'll split them into small pieces and create pull requests separately.

With this branch, one can run dist/bin/jython without the -S option.

Hi @isaiah this one is indeed a little too big to review at once. I have already merged two of the smaller pull requests, and I am working on a third. After I get done with all of the other pull requests, I'll see what's left of this one (assuming that there is more to this one than just the sum of the small ones). It might be manageable after that. I'll let you know!

Hi Isaiah, sorry I have neglected looking at these for so long. I just merged the third of the smaller patches. The others have conflicts, and I have time again to evaluate. This patch is a bit too big for me, if you could break it up into smaller ones I'll be able to get through it quicker. I will try to be more on top of these - it is great work!

@fwierzbicki Thanks for reviewing, I would like to see my changes in the main repository so someone else interested can have a better start point, there are simply too much work to do :)

I've fixed PEP-3135 super() without parameter, PEP-380 sub-generators and PEP-3134 exception chaining, the main features that blocked proper execution of the specs, currently it can run and report errors/failure when run a certain spec.

Isalah, I would like to see this in the main repo too :) -- how about this, if you can get the conflicts resolved for this large pull request, I'll do my best to review it this week (probably over the weekend) and try to get it in as it is. I understand that it would be a lot of work to break it up. The fact that it can run Jython without the -S is a great step forward.

@fwierzbicki That sounds great, I'll fix the conflicts. The change set is too big to be reviewed on github, that's probably because I introduced the 3.5.1 stdlib, you can focus on the src folder to get less noise.

Hi Isaiah, I merged the site.py branch, but then ran into some trouble. The grammar didn't work until I did the following:

 //raise_stmt: 'raise' [test ['from' test]]
 raise_stmt
-    ;
-
-raise_stmt
 @init {
     stmt stype = null;
 }

And FilenoUtil is missing an import of ChannelFD, there may be other issues - I can't compile with the ChannelFD issue.
