After some failures in AMD64 FreeBSD CURRENT Debug 3.x buildbots
regarding tests in test_multiprocessing_spawn and after examining
similar failures in test_socket, some errors in the calculation of
ancillary data buffers were found in multiprocessing.reduction.
CMSG_LEN() can often be used as the buffer size for recvmsg() to
receive a single item of ancillary data, but RFC 3542 requires portable
applications to use CMSG_SPACE() and thus include space for padding,
even when the item will be the last in the buffer.
The failures we experience are due to the usage of CMSG_LEN() instead of
CMSG_SPACE().

Improvements:
1. Include the number of valid data characters in the error message.
2. Mention "number of data characters" rather than "length".

After some failures in AMD64 FreeBSD CURRENT Debug 3.x buildbots
regarding tests in test_socket that are using
testFDPassSeparateMinSpace(), FreeBDS revision 337423 was pointed
out to be the reason the test started to fail.
A close examination of the manpage for cmsg_space(3) reveals that
the number of file descriptors needs to be taken into account when
using CMSG_LEN().
This commit fixes tests in test_socket to use correctly CMSG_LEN, taking
into account the number of FDs.

Use a monotonic clock to compute timeouts in :meth:`Executor.map` and :func:`as_completed`, in order to prevent timeouts from deviating when the system clock is adjusted.
This may not be sufficient on all systems. On POSIX for example, the actual waiting (e.g. in ``sem_timedwait``) is specified to rely on the CLOCK_REALTIME clock.

Currently, the docs state that when doing `Type[X]`, X is only allowed to
be a class, a union of classes, and Any. This pull request amends
that sentence to clarify X may also be a typevar (or a union involving
classes, Any, and TypeVars).

Have macOS 10.9+ installer builds for 3.7.1rc and 3.6.7rc use a development
snapshot of Tk 8.6 (post-8.6.8) to mitigate certain scroller issues seen
with IDLE and tkinter apps.
When dict subclass overrides order (`__iter__()`, `keys()`, and `items()`), `dict(o)`
should use it instead of dict ordering.

The SAX parser no longer processes general external entities by default
to increase security. Before, the parser created network connections
to fetch remote files or loaded local files from the file system for DTD
and entities.

Fix a crash with musl libc (on Alpine Linux) when the script filename
specified on the command line doesn't exist. pymain_open_filename()
now gets the current core configuration from the interpreter state.
Modify the code to make it closer to the master branch:
* Rename _Py_CommandLineDetails to _PyCmdline
* Remove _PyMain.config: replaced with a local variable
'local_config' in pymain_init()
* Reorganize pymain_main(): move code using the "local config"
into pymain_init()
* As soon as possible, switch from the local config to the core
configuration attached to the interpreter.
Use "backslashreplace" instead of "unicode-escape". It is not
implementation depended and escapes only non-encodable characters.
Also simplify the code.

OpenSSL follows the convention that whenever you call a function, it
returns an error indicator value; and if this value is negative, then
you need to go look at the actual error code to see what happened.
Commit c6fd1c1c3a introduced a small mistake in
_ssl__SSLSocket_shutdown_impl: instead of checking whether the error
indicator was negative, it started checking whether the actual error
code was negative, and it turns out that the error codes are never
negative. So the effect was that 'unwrap()' lost the ability to raise
SSL errors.

We cannot simply call locale.getpreferredencoding() here,
as GDB might have been linked against a different version
of Python with a different encoding and coercion policy
with respect to PEP 538 and PEP 540.
Thanks to Victor Stinner for a hint on how to fix this.
