Refactor http_send_response() into http_prepare_response()
The function http_send_response() did too much. It not only took
the request fields and built them together into a response, it
delegated too little and many functions were "hacked" into it, for
instance shady directory-changes for vhosts and hand-construction
of response structs.

The preparations for a rework were already made in previous commits,
including a tighter focus on the response-struct itself. Instead of
doing everything locally in the http_send_response() function, the
new http_prepare_response() only really takes the request-struct and
builds a response-struct. The response-struct is expanded such that
it's possible to do the data-sending simply with the response-struct
itself and not any other magic parameters that just drop out of the
function.

Another matter are the http_send_status()-calls. Because the
aforementioned function is so central, this refactoring has included
many areas. Instead of calling http_send_status() in every error-case,
which makes little sense now given we first delegate everything through
a response struct, errors are just sent as a return value and caught
centrally (in serve() in main.c), which centralizes the error handling
a bit.

It might look a bit strange now and it might not be clear in which
direction this is going, but subsequent commits will hopefully give
clarity in this regard.
