Subject: [PATCH] HTTP: removed unused r->port_start and r->port_end.

Neither r->port_start nor r->port_end were ever used.

The r->port_end is set by the parser, though it was never used by
the following code (and was never usable, since not copied by the
ngx_http_alloc_large_header_buffer() without r->port_start set).
