Title: Improved speed of querystring

This is the same as [#3267](https://github.com/joyent/node/pull/3267), I only pushed things a bit further:
* `Array#slice` isn't called anymore, instead, the loop gets shortened.
* Also changed the handling of keys without values. They should now perform better.

I removed the unnecessary switch statement again (the one with a single case), I hope that's okay.
