encoding (not equal to 'utf-8') was specified on the second line.

the first line contains anything except a comment.

* As a consequence, 'python -x' works now again with files with the source
encoding declarations specified on the second file, and can be used again
to make Python batch files on Windows.

Issue #19422: Explicitly disallow non-SOCK_STREAM sockets in the ssl module, rather than silently let them emit clear text data.

In issue 20074 it was pointed out that getpass would fail with a traceback if
stdin was, for example /dev/null, which is a non-unlikely scenario.

Also backported the tests from issue 17484 as modified by issue 18116.

(What I really did was copy getpass.py and test_getpass.py from their
state on tip as of 17bd04fbf3d3).
