Fix infinite loop in workaround for aiohttp issue 4630
If a response ends with '0\r\n' or '0\r\n\r', ClientResponse._read loops forever trying to read 4 more bytes.
In addition, bump that read to 1 KiB for better worst-case performance.

Don't close raw data tempfiles until the response gets GC'd
Closing the raw data tempfiles immediately on connection reuse caused any response reading to fail with an I/O error if another request started on the same connection in the meantime. Delaying the closing until the response object falls out of scope and gets GC'd ensures that as long as there is a reference to that object, it can be read from, at the expense of a possibly larger memory overhead.

Stop deduping small responses
For small responses, the additional headers for the revisit outweigh the payload truncation savings. The chosen limit of 100 bytes is completely arbitrary and not backed by any real-world data.
