The tests that would have help avoid bug #73948 and all that mess :)

* bzrlib/transport/http/response.py:
(handle_response): Translate a 416 http error code into a bzr
exception.

* bzrlib/transport/http/_urllib2_wrappers.py:
(HTTPDefaultErrorHandler.http_error_default): Translate a 416 http
error code into a bzr exception.

* bzrlib/transport/http/_pycurl.py:
(PyCurlTransport._curl_perform): It could happen that pycrul
itself detect a short read.

* bzrlib/transport/http/__init__.py:
(HttpTransportBase._retry_get): New method, factorizing the retry
logic.
(HttpTransportBase.readv): We can have exception during the
initial GET worth degrading the range requirements (i.e. retrying
the GET request with either single or not ranges).

* bzrlib/tests/test_transport_implementations.py:
(TransportTests.test_readv_short_read): InvalidRange can also be
raised.

* bzrlib/tests/test_http.py:
(TestRangeRequestServer.test_readv_invalid_ranges): Was named
test_readv_short_read, the new name make the intent
clearer. Depending of the code path used (urllib or pycurl), both
exceptions can be raised.

* bzrlib/tests/HttpServer.py:
(TestingHTTPRequestHandler.do_GET): If invalid ranges are
specified, returns a 416 instead of the whole file (both are valid
according to the RFC).
