lib-dcrypt: Don't finalize encryption on o_stream_flush()

For example the default o_stream_uncork() implementation enforces flushing
and it's probably better not to change that. In general there's really no
reason to perform the finalization at flush when the stream can't be written
to anymore (whereas lib-compression ostreams allow writes after flushes).

lib-http: client: Fixed hang occurring when nested ioloops are used in response callbacks.

To prevent missing disconnect events, i_stream_read() is called once a change in ioloop is detected.
However, if something was actually read into the stream, the input handler was never called.
So, a response could linger in the stream buffer, without being handled, thereby causing the connection to hang indefinitely.
An additional input event could end the hang, but sometimes this doesn't happen before the request times out.

This problem was seen in test-http-payload once in about 10 invocations.
Obox uses nested ioloops, to this applies there.
