Barney Gale 7e31d6dea2 gh-88569: add ntpath.isreserved() (#95486) 
Add `ntpath.isreserved()`, which identifies reserved pathnames such as "NUL", "AUX" and "CON".

Deprecate `pathlib.PurePath.is_reserved()`.

Barney Gale e4ff131e01 GH-44626, GH-105476: Fix ntpath.isabs() handling of part-absolute paths (#113829) 
On Windows, `os.path.isabs()` now returns `False` when given a path that
starts with exactly one (back)slash. This is more compatible with other
functions in `os.path`, and with Microsoft's own documentation.

Also adjust `pathlib.PureWindowsPath.is_absolute()` to call
`ntpath.isabs()`, which corrects its handling of partial UNC/device paths
like `//foo`.

박문식 d33aa18f15 gh-82367: Use FindFirstFile Win32 API in ntpath.realpath() (GH-110298) 
* Use `FindFirstFile` Win32 API to fix a bug where `ntpath.realpath()`
breaks out of traversing a series of paths where a (handled)
`ERROR_ACCESS_DENIED` or `ERROR_SHARING_VIOLATION` occurs.
* Update docs to reflect that `ntpath.realpath()` eliminates MS-DOS
style names.

Steve Dower 99fcf15052 bpo-45582: Port getpath[p].c to Python (GH-29041) 
The getpath.py file is frozen at build time and executed as code over a namespace. It is never imported, nor is it meant to be importable or reusable. However, it should be easier to read, modify, and patch than the previous code.

This commit attempts to preserve every previously tested quirk, but these may be changed in the future to better align platforms.

Barney Gale 3f3d82b848 bpo-39899: os.path.expanduser(): don't guess other Windows users' home directories if the basename of the current user's home directory doesn't match their username. (GH-18841) 
This makes `ntpath.expanduser()` match `pathlib.Path.expanduser()` in this regard, and is more in line with `posixpath.expanduser()`'s cautious approach.

Also remove the near-duplicate implementation of `expanduser()` in pathlib, and by doing so fix a bug where KeyError could be raised when expanding another user's home directory.

instead of raising ValueError or its subclasses UnicodeEncodeError
and UnicodeDecodeError for paths that contain characters or bytes
unrepresentative at the OS level.
