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

webrick/httprequest: limit request headers size
We use the same 112 KB limit started (AFAIK) by Mongrel, Thin,
and Puma to prevent malicious users from using up all the memory
with a single request. This also limits the damage done by
excessive ranges in multipart Range: requests.
Due to the way we rely on IO#gets and the desire to keep
the code simple, the actual maximum header may be 4093 bytes
larger than 112 KB, but we're splitting hairs at that point.
* lib/webrick/httprequest.rb: define MAX_HEADER_LENGTH
(read_header): raise when headers exceed max length

webrick/httpservlet/cgihandler: reduce memory use
WEBrick::HTTPRequest#body can be passed a block to process the
body in chunks. Use this feature to avoid building a giant
string in memory.
* lib/webrick/httpservlet/cgihandler.rb (do_GET):
avoid reading entire request body into memory
(do_POST is aliased to do_GET, so it handles bodies)

webrick/httprequest: use InputBufferSize for chunked requests
While WEBrick::HTTPRequest#body provides a Proc interface

the server to use an excessively large chunk size.

read and block.call to :InputBufferSize in config.

webrick: add test for Digest auth-int
No changes to the actual code, this is a new test for
a feature for which no tests existed. I don't understand
the Digest authentication code well at all, but this is

webrick/httpauth/digestauth: stream req.body
WARNING! WARNING! WARNING! LIKELY BROKEN CHANGE
Pass a proc to WEBrick::HTTPRequest#body to avoid reading a
potentially large request body into memory during
authentication.
WARNING! this will break apps completely which want to do
something with the body besides calculating the MD5 digest
of it.
Also, keep in mind that probably nobody uses "auth-int".
Servers such as Apache, lighttpd, nginx don't seem to
support it; nor does curl when using POST/PUT bodies;
and we didn't have tests for it until now...

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.

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.
