bpo-43972: Set content-length to 0 for http.server.SimpleHTTPRequestHandler 301s (GH-25705)

* Set content-length for simple http server 301s

When http.server.SimpleHTTPRequestHandler sends a 301 (Moved
Permanently) due to a missing file, it does not set a Content-Length
of 0. Unfortunately, certain clients can be left waiting for the
connection to be closed in this circumstance, even though no body
will be sent. At time of writing, both curl and Firefox demonstrate
this behavior.

* Test Content-Length on simple http server redirect

When serving a redirect, the SimpleHTTPRequestHandler will now send
`Content-Length: 0`. Several tests for http.server already cover
various behaviors and checks including redirection. This change only
adds one check for the expected Content-Length on the simplest case
for a redirect.

* Add news entry for SimpleHTTPRequestHandler fix

* Clarify the specific kind of 301

bpo-40297: Fix test_socket.CANTest.testSendFrame (GH-19548)

The address tuple for CAN_RAW no longer returns the address family
after the introduction of CAN ISO-TP support in a30f6d45ac3. However,
updating test_socket.CANTest.testSendFrame was missed as part of the
change, so the test incorrectly attempts to index past the last tuple
item to retrieve the address family.

This removes the now-redundant check for equality against socket.AF_CAN,
as the tuple will not contain the address family.

anything under ``/System`` was assumed to be in an SDK which causes problems

bpo-43284: Update platform.win32_ver to use _syscmd_ver instead of sys.getwindowsversion() (GH-25500)

The sys module uses the kernel32.dll version number, which can vary from the "actual" Windows version.
Since the best option for getting the version is WMI (which is expensive), we switch back to launching cmd.exe (which is also expensive, but a lot less code on our part).
sys.getwindowsversion() is not updated to avoid launching executables from that module.
