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...

Be sure we do not try to open a pipe to read from, since we care
about mtime in all cases.
