[RFC] MERGE: chunked-encoding patch for 3.0

The Gentoo project have back-ported the chunked-encoding changes from
3.1 to 3.0.

Votes please on whether it should be merged into 3.0 officially or left
as a patch?

I've held off so far due to 3.0 being under freeze and 3.1 already
available for those who need it. Also the amount of work needed to do
this counted against.

Alin brings up a good point though about other peoples views of
stability being stricter despite their need of this being no less.

With the work now being done I'm minded to apply if others agree.

I've held off since 30 is stable
