Poll inner connection until EOF after gzip decoder is complete

[Andrey36652]

Fix for #2381

[Andrey36652]

Should I expand the fix on all other decompression methods?

[seanmonstar]

If they all have the same characteristic, namely that they know they ended before reading EOF, then they probably all suffer from the same thing.

[Andrey36652]

Should I add tests for all other decompression methods?

[seanmonstar]

You can. If so, I'd do with a for loop, or some pattern to reduce the duplicate parts.

[Andrey36652]

Can reqwest deal with such cases (multiple compression algorithms)?

// Multiple, in the order in which they were applied
Content-Encoding: deflate, gzip

[seanmonstar]

I don't think it can, but not a single person has filed saying they needed it. So I suspect that is more of a theoretical part of the spec, and not something that servers ever actually do.

So I wouldn't bother supporting it for now, it'd make things complicated and we don't seem to need it.

[Andrey36652]

I don't know why it fails style check, cargo fmt -- --check locallly shows no errors.

[seanmonstar]

Some code doesn't get formatted automatically because of conditional #[cfg] flags leaving some files out. You can run cargo fmt -- $(find . -name '*.rs' -print) to get all of them.

Excellent, excellent, excellent work. Thanks so much for cleaning this up! <3
