The values of @header are expected to be all strings;
WEBrick::HTTPResponse::[]=(key, val) explicitly converts the second
argument to a string and assigns it to @header hash.
However, there were some points in WEBrick internal code that assigns
non-String to @header. This change fixes the issues.
The values are checked by `header_value =~ /\r\n/` in check_header.
The type confusion caused conflict with removal of `Object#=~`
[Feature #15231].

Use the new Proc response body feature to generate a multipart
range response dynamically. We use a flat array to minimize
object overhead as much as possible; as many ranges may fit
into an HTTP request header.
* lib/webrick/httpservlet/filehandler.rb (multipart_body): new method
(make_partial_content): use multipart_body

Content-Length is ignored by WEBrick::HTTPResponse even if we
calculate it, so instead we chunk responses to HTTP/1.1 clients
and terminate HTTP/1.0 connections.

This is also compatible with range responses generated
by Rack::File (tested with rack 2.0.3).
* lib/webrick/httpresponse.rb (send_body_io): use Content-Range

This makes future code audits easier. None of these changes
fix realistic remote code execution vulnerabilities because
we stat(2) before attempting Kernel#open.
