Specifically, make sure the 'Object', 'Python' and 'Include' directories
in the build directory take precedence over the source directory if we're
an out-of-tree build.

Fix typeslots.inc so that it gets generated into the build directory.

This change includes replacing the single-line signature documentation
with a more complete multiple-line signature.

Add handling of the 6.2 release line, aka Windows 8 and Windows 2012 Server.

Issue #12947: revert earlier workaround and use a monkey-patch to enable showing doctest directives only in the doctest docs.

misleading error message stating that args[0] did not exist when
either the cwd or executable keyword arguments specified a path that
did not exist.

It now keeps track of if the child got as far as preexec and reports it if
not back to the parent via a special "noexec" error message value in
the error pipe so that the cwd can be blamed for a failed chdir
instead of the exec of the executable being blamed instead.

The executable is also always reported accurately when exec fails.

Unittests enhanced to cover these cases.

Issue #16115: Improve subprocess.Popen() documentation around args, shell, and executable arguments.

Done with great native-speaker help from R. David Murray.

This commit rewrites the docstring for int() to incorporate the documentation
changes made in issue #16036.  It also switches the docstrings for int(),
str(), range(), and slice() to use multi-line signatures.
