Fix #179368 by keeping the current range hint on ShortReadvErrors.

* response.py:
(RangeFile._checked_read): Avoid huge buffering when huge seeks
are required.

* _urllib2_wrappers.py:
(Response.finish): Check for end-of-file or we'll loop if the
server lied about Content-Length.

* __init__.py:
(HttpTransportBase._readv): When a ShortReadvError occurs, try
again, staying in multiple range mode and degrades only if the
error occurs again for the same offset.

* test_http_response.py:
(TestRangeFileMultipleRanges): Add a test to exercise the buffer
overflow protection code.

* test_http.py:
(TestMultipleRangeWithoutContentLengthServer): Emulate lighttpd
behavior regarding bug #179368.
