MEDIUM: filters: Replace filter_http_headers callback by an analyzer
This new analyzer will be called for each HTTP request/response, before the
parsing of the body. It is identified by AN_FLT_HTTP_HDRS.
Special care was taken about the following condition :
* the frontend is a TCP proxy
* filters are defined in the frontend section
* the selected backend is a HTTP proxy
So, this patch explicitly add AN_FLT_HTTP_HDRS analyzer on the request and the
response channels when the backend is a HTTP proxy and when there are filters
attatched on the stream.
This patch simplifies http_request_forward_body and http_response_forward_body
functions.
