Added support for trailers in HTTP responses.
Example:
ngx_table_elt_t *h;
h = ngx_list_push(&r->headers_out.trailers);
if (h == NULL) {
return NGX_ERROR;
}
ngx_str_set(&h->key, "Fun");
ngx_str_set(&h->value, "with trailers");
h->hash = ngx_hash_key_lc(h->key.data, h->key.len);
The code above adds "Fun: with trailers" trailer to the response.
Modules that want to emit trailers must set r->expect_trailers = 1
in header filter, otherwise they might not be emitted for HTTP/1.1
responses that aren't already chunked.
This change also adds $sent_trailer_* variables.
