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.

* use ctx manager for memoryview()
* update doc
* remove outdated doc
* remove last CopyFileEx remnants
* OSX - use fcopyfile(3) instead of copyfile(3)
...as an extra safety measure: in case src/dst are "exotic" files (non
regular or living on a network fs etc.) we better fail on open() instead
of copyfile(3) as we're not quite sure what's gonna happen in that
case.
* update doc
Imporoved the documentation and tests for make_archive() and unpack_archive().
Improved error handling when corresponding compress module is not available.
Brake circular dependency between shutil and tarfile modules.

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).

Patch by Greg Ward.
Initial patch by Kelsey Hightower. Approved by Raymond. A test was
non-trivial to write without calling the private function directly, so
we moved that for later.
Also add an explicit test for safe implementation usage on supported platforms.
As a side effect, this commit adds a module-level attribute 'rmtree_is_safe'
which offers introspection whether the current rmtree implementation is safe
against symlink attacks.
Many functions now support "dir_fd" and "follow_symlinks" parameters;
some also support accepting an open file descriptor in place of of a path
string. Added os.support_* collections as LBYL helpers. Removed many
functions only previously seen in 3.3 alpha releases (often starting with
"f" or "l", or ending with "at"). Originally suggested by Serhiy Storchaka;
implemented by Larry Hastings.
Removed futimens as it is now redundant.
Changed shutil.copystat to use st_atime_ns and st_mtime_ns from os.stat
and ns= parameter to utime--it once again preserves exact metadata on Linux!
and the source is a symlink, shutil.move() now recreates a symlink on the
destination instead of copying the file contents.
Patch by Jonathan Niehof and Hynek Schlawack.
