range_filter_module get duplicated Accept-Ranges response headers

[webber]

Hi, 

Sorry to bother you, I rechange the patch as follow: 

Previously, if an Accept-Ranges header was already present in the first
slice
response, client received two copies of this header. Now, the slice filters
removes the Accept-Ranges header for partital request and if original server

response Accept-Ranges header, has  from the response prior to setting the
r->allow_ranges flag.
