locale-specific number formatting from a string representing a number,
without then converting it to a specific type.  Patch by Cédric Krier.

Issue #22676: Make the pickling of global objects which don't have a __module__ attribute less slow.

Original patch by Tal Einat.

The distutils module still supports it to build extensions.

Replace os.popen() with subprocess.Popen() in the uuid module.

This makes it possible to examine the errors from unittest discovery
without executing the test suite - important when the test suite may
be very large, or when enumerating the test ids from a test suite.

closefd was documented in the open docs but not the matching FileIO
class documented. Further, closefd, part of the core state for the
object was not shown.

In review it was noted that the open docs are a little confusing about
the interaction between closefd and paths, so tweaked them at the same
time.
