Add parameter to iter_content to disable content decoding

[domoritz]

I wanted to use requests to transfer a file chunk by chunk. However, before I transferred the body, I copied a header from the original response to the new response. Since request decodes gzip and deflate, the header was wrong and my content couldn't be interpreted by the browser.

This patch adds an option to iter_content. to disable decoding of gzip or deflate content.

iter_content() is supposed to always decode thus adding parameter changing this is not the right thing to do and I guess it won't be accepted. I thing there was some discussion about adding similar method for raw data but the idea was rejected. You could find this discussion in closed issues and voice your concern there. Isn't raw what you need?

Okay, thanks for the input. I have a solution for myself but thought that other people might be interested in this as well. I'll close the issue then.

What's your solution?

1st: Copy the code from iter_content but without the call that deflates or unzips.
2nd (hack): Set the content-encoding to "" before calling iter_content.

Interesting. See #844 for a related issue (related to byte encodings of Unicode codepoints, rather than gzip).
