response-header-options: consider the response headers for options

Take the response headers into account when determining the options
for the request. Also adds tests for this.

native-fetcher: timeouts

After more testing, it turns out that the timer that is initially set
in Init() remains active throughout the whole lifetime of the fetch.

This reverts the previous change, which isn't correct, and replaces
all TODO's concerning timers with a comment about that we don't need
them.
