Rename the HttpBody export to Body

[seanmonstar]

When the concrete Body struct is removed, we can export the http_body::Body trait as just Body.

What would be the advantage in case of import both trait and struct?

[seanmonstar]

The struct will be removed, as detailed in #2345.

I am just starting up with Hyper so would like to work on this task (if that's ok). By renaming and exporting the http_body::Body trait as just Body, I assume you are talking about updating the following:

https://github.com/hyperium/hyper/blob/84f6ae78d62f0ca3b85f86ea92887dc46ed9717e/src/body/mod.rs#L19-L23

But since the concrete Body type is already exported as Body, wouldn't that cause a conflict? Should I get rid of the concrete type export?

[seanmonstar]

Yes, we'd need to finish removing parts of Body, and renaming that. Then this one would be straightforward.

[RajivTS]

Is there a separate task that I can work on to remove parts of Body?

[seanmonstar]

@RajivTS The top comment in #2345 includes a list of tasks, and I tried to put them in order of unblocking the next one. Some are linked to specific issues, we can make more of them issues too.

[seanmonstar]

This is no longer blocked, since Body was renamed to Recv as a stop-gap (#2963).

@seanmonstar Created PR to address this, would appreciate a review to understand if I missed something.
