Loop with String#scan without creating substrings

Create the substrings necessary parts only, instead of cutting the
rest of the buffer.  Also removed a useless, probable typo, regexp.

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...

When you change this to true, you may need to add more tests.

  Literal texts in HTTP ABNF is case-insensitive (RFC2616 2.1),
  and a ample implementation in RFC2617 also ignores the case
  of algorithms. So now this ignores those cases.
  [ruby-dev:43965] [Feature #4936]

* lib/webrick/httpauth/digestauth.rb (initialize):
  Because of above, opera_hack is useless and removed.
