Running AWS SDK with ruby -d flag generates many warnings

[SpencerBrown]

Try running any app with the -d flag, you'll get a lot of messages. Suggestion is to review these and change code to eliminate them where possible. It makes it hard to debug an application with floods of messages like these.

Here's a sample:

I'll take a look at some of these.

I fixed quite a few of them last week and I just pushed another commit cleaning up more.

I finished the updates. The SDK no longer generates any of its own warnings when running the unit and integration tests. These changes should be part of the next release.
