Unable to iterate over chunks as sent by server.

[ahane]

Long story short

I am talking to a HTTP server that uses transfer-encoding: chunked to stream records, whith each chunk representing one record.
aiohttp currently offers no API for iterating over the chunks exactly as sent by the server.

Expected behaviour

I would expect the response.content.iter_chunked(n) method to default to the chunking already defined by the server if n=None or a special flag is passed.

See the similar method in the Requests library that shows the desired behaviour.

Actual behaviour

n=None returns an empty bytestring, while n=-1 doesn't return at all.

There is no method to recover the chunking of the server.

you can use readany, it returns data available in buffer. but right now it is not possible.
would you like to provide PR?

[ahane]

yes ;) readany does join all chunks in the buffer into one bytestring though
