make s3 aiori that uses the official s3 c api

[glennklockwood]

It looks like both our S3 backends use libraries that are no longer being maintained. Fortunately, AWS now has an "official" C API: https://github.com/awslabs/aws-c-s3

For sustainability, we should probably migrate to that and retire out the other two flavors of S3 support at some point.

Sounds great, indeed! Will work on it in time.

[JulianKunkel]

The library dependencies are an absolute atrocity.

[glennklockwood]

That's too bad. Should we close this or leave it on the backlog?

[JulianKunkel]

I actually started to work on it: aws-s3-branch
At least the script to compile the dependencies somehow works.
The status of the branch is:

1. Script to compile the s3 depencency
2. Integration of the new module into the compilation cycle
3. Tested initialization - found a bug in AWS-S3 which is resolved

I would be, of course, happy if someone had time to proceed - I will try to do it in Q1, as S3 is very important to me.

I am currently very interested in this feature, and may pick up the work on it myself if nobody else is pursuing it. @JulianKunkel , I assume your branch is the place to start?

[JulianKunkel]

@matthewcurry that sounds great, I didn't have the need to proceed in Q1.
