Extended attributes can only be set on user-writeable files, but shutil previously
first chmod()ed the destination file to the source's permissions and then tried to
copy xattrs. This will cause failures if attempting to copy read-only files with
xattrs, as occurs with Git clones on Lustre FS.

* bpo-35755: shutil.which() uses os.confstr("CS_PATH") (GH-12858)
shutil.which() and distutils.spawn.find_executable() now use
os.confstr("CS_PATH") if available instead of os.defpath, if the PATH
environment variable is not set.
Don't use os.confstr("CS_PATH") nor os.defpath if the PATH
environment variable is set to an empty string.
Changes:
* find_executable() now starts by checking for the executable in the
current working directly case. Add an explicit
"if not path: return None".
* Add tests for PATH='' (empty string), PATH=':' and for PATHEXT.

* bpo-35755: Remove current directory from posixpath.defpath (GH-11586)

Fix the documentation of copy2, as it does not copy file ownership (user and
group), only mode, mtime, atime and flags.
The original text was confusing to developers as it suggested that this
command is the same as 'cp -p', but according to cp(1), '-p' copies file
ownership as well.
Clarify which metadata is copied by shutil.copystat in its docstring.

Issue #26801: Fix error handling in shutil.get_terminal_size(), catch
AttributeError instead of NameError. Patch written by Emanuel Barry.
test_shutil: skip the functional test using "stty size" command if
os.get_terminal_size() is missing.
An exception handler assumed that that OSError objects always have a
'winerror' attribute. That is not the case, so the exception handler
itself raised AttributeError when run on Linux (and, presumably, any
other non-Windows OS).
