* Strings with length from 2**31-1 to 2**32-2 always caused MemoryError,
it doesn't matter how much memory is available.
* Strings with length exactly 2**32-1 caused OSError.
* Strings longer than 2**32-1 characters were truncated due to integer overflow bug.
* Strings containing the null character were truncated at the first null character.
Now strings longer than 2**31-1 characters caused OverflowError and the null character is allowed.
We no longer add a root to device paths such as `//./PhysicalDrive0`,
`//?/BootPartition` and `//./c:` while normalizing. We also avoid adding a
root to incomplete UNC share paths, like `//`, `//a` and `//a/`.

This brings the Python implementation of `ntpath.normpath()` in line with the C implementation added in 99fcf15

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.
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.
Ensure isabs() is always True for \\?\ prefixed paths
Avoid unnecessary usage of readlink() to avoid resolving broken links incorrectly
Ensure shutil tests run in test directory
* Fix case-sensitive comparison
test_nt_helpers assumed that two versions of a Windows path could be compared case-sensitively. This is not the case, and the difference can be triggered (apparently) by running the test on a path somewhere below a Junction.
* splitunc() no more return illegal result for paths with redundant slashes.
* splitunc() now correctly processes the 'İ' character
(U+0130, LATIN CAPITAL LETTER I WITH DOT ABOVE).
* Deprecation warnings now emitted for every use of splitunc().
* Added tests for splitunc().
