oob_gc: reimplement to fix breakage and add tests

This was broken since v3.3.1[1] and v1.1.6[2] since nginx relies on
a closed socket (and not Content-Length/Transfer-Encoding) to
detect a response completion.  We have to close the client
socket before invoking GC to ensure the client sees the response
in a timely manner.
