oohttp: add header ordering support

[fedosgad]

I have forked oohttp (this is a great library btw, thanks a lot for it!) to add support for features absent in stdlib's http client, such as header ordering (including HTTP2 headers and pseudoheaders), manipulating HTTP2 settings and HTTP2 SERVER PUSH. My intent is to make mimicking "normal" web browsers (Chrome/FF/you name it) simplier and more accurate.

Code is available at github.com/fedosgad/oohttp. Currently, I've finished header ordering (ported from fhttp).

Changes were made in (I hope) maintainable way, similar to what oohttp itself has done (see PATCHING.md). I would like to contribute those changes back to oohttp. What do you think about it?

[bassosimone]

Absolutely! I'll add to my sprint to take a look at your changes, thank you!

[fedosgad]

That's great! Feel free to ping me if there are any questions.

I am very much interested in seeing this get rolled in. @bassosimone would it be helpful for me to put together a PR, or is this something you've already started on?

[bassosimone]

@nathanejohnson it seems there is already an open PR: ooni/oohttp#46

Unfortunately we are going to be discontinuing our oohttp golang std lib http fork, as it's too expensive for us to maintain.

As a result I am closing this issue.

Sad to hear this but thanks for the early warning!
Do you mind sharing what libraries you will use instead of oohttp?
