webrick: support Proc objects as body responses
* lib/webrick/httpresponse.rb (send_body): call send_body_proc
(send_body_proc): new method
(class ChunkedWrapper): new class
* test/webrick/test_httpresponse.rb (test_send_body_proc): new test
(test_send_body_proc_chunked): ditto
[Feature #855]
webrick: favor .write over << method
This will make the next change to use IO.copy_stream
easier-to-read. When we can drop Ruby 2.4 support in a few
years, this will allow us to use writev(2) with multiple
arguments for headers and chunked responses.
* lib/webrick/cgi.rb (write): new wrapper method
lib/webrick/httpresponse.rb: (send_header): use socket.write
(send_body_io): ditto
(send_body_string): ditto
(send_body_proc): ditto
(_write_data): ditto
(ChunkedWrapper#write): ditto
(_send_file): ditto

webrick/httpresponse: IO.copy_stream for regular files
Remove the redundant _send_file method since its functionality
is unnecessary with IO.copy_stream. IO.copy_stream also allows
the use of sendfile under some OSes to speed up copies to
non-TLS sockets.
Testing with "curl >/dev/null" and "ruby -run -e httpd" to
read a 1G file over Linux loopback reveals a reduction from
around ~0.770 to ~0.490 seconds on the client side.
* lib/webrick/httpresponse.rb (send_body_io): use IO.copy_stream
(_send_file): remove

webrick: use IO.copy_stream for single range response
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
* lib/webrick/httpservlet/filehandler.rb (make_partial_content):
use File object for the single range case
* test/webrick/test_filehandler.rb (get_res_body): use send_body
to test result

test/webrick/test_filehandler.rb: stricter multipart range test
We need to ensure we generate compatibile output in
the face of future changes
* test/webrick/test_filehandler.rb (test_make_partial_content):

webrick: quiet warning for multi-part ranges
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.
* lib/webrick/httpservlet/filehandler.rb (make_partial_content):
quiet warning

webrick/httpresponse: make ChunkedWrapper copy_stream-compatible
The .write method needs to return the number of bytes written
to avoid confusing IO.copy_stream.
* lib/webrick/httpresponse.rb (ChunkedWrapper#write): return bytes written
(ChunkedWrapper#<<): return self

webrick: use IO.copy_stream for multipart response
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
get rid of test error/failure on Windows introduced at r62955
* lib/webrick/httpresponse.rb (send_body_io): use seek if NotImplementedError
is raised in IO.copy_stream with offset.
* lib/webrick/httpservlet/filehandler.rb (multipart_body): ditto.
