* Fix cannot create Windows directory in root
Fixes#20306, a regression bug with `createDir` caused by
`23e0160af283bb0bb573a86145e6c1c792780d49`.
The issue is that, if the path consists only of a drive and a single
directory (e.g. "Y:\nimcache2" in the original issue), then no
directories will be created. This works fine if there are multiple
directories (e.g. "Y:\nimcache2\test").
In the case of "Y:\nimcache2", `omitNext` in `createDir` is `false` on
the last condition in `createDir`. This means that the "nimcache2"
directory will not be created, and no exception will be raised.
Fixed by refactoring to use `parentDirs` iterator instead of iterating
over the string characters. Motivation is reduced code complexity.
Will not test the specific "C:\test" `createDir` case, since there is no
standard Windows drive with write permissions in the root. Creating a
custom drive-mapping to Windows Temp is a non-option. That could mess
up some users running the test.
Added `parentDirs` tests since they are lacking on for POSIX paths.
* Fix `createDir("")` causing error
The change to `createDir` caused `createDir("")` to raise an error,
where it previously didn't. Fixed so `createDir("")` does not fail, and
added test case.
* Add improved Windows UNC path support in std/os
Original issue: `std/os.createDir` tries to create every component of
the given path as a directory. The problem is that `createDir`
interprets every backslash/slash as a path separator. For a UNC path
this is incorrect. E.g. one UNC form is `\\Server\Volume\Path`. It's an
error to create the `\\Server` directory, as well as creating
`\\Server\Volume`.
Add `ntpath.nim` module with `splitDrive` proc. This implements UNC path
parsing as implemented in the Python `ntpath.py` module. The following
UNC forms are supported:
* `\\Server\Volume\Path`
* `\\?\Volume\Path`
* `\\?\UNC\Server\Volume\Path`
Improves support for UNC paths in various procs in `std/os`:
---
* pathnorm.addNormalizePath
* Issue: This had incomplete support for UNC paths
* The UNC prefix (first 2 characters of a UNC path) was assumed to
be exactly `\\`, but it can be `//` and `\/`, etc. as well
* Also, the UNC prefix must be normalized to the `dirSep` argument
of `addNormalizePath`
* Resolution: Changed to account for different UNC prefixes, and
normalizing the prefixes according to `dirSep`
* Affected procs that get tests: `relativePath`, `joinPath`
* Issue: The server/volume part of UNC paths can be stripped when
normalizing `..` path components
* This error should be negligable, so ignoring this
* splitPath
* Now make sure the UNC drive is not split; return the UNC drive as
`head` if the UNC drive is the only component of the path
* Consequently fixes `extractFilename`, `lastPathPart`
* parentDir / `/../`
* Strip away drive before working on the path, prepending the drive
after all work is done - prevents stripping UNC components
* Return empty string if drive component is the only component; this
is the behavior for POSIX paths as well
* Alternative implementation: Just call something like
`pathnorm.normalizePath(path & "/..")` for the whole proc - maybe
too big of a change
* tailDir
* If drive is present in path, just split that from path and return
path
* parentDirs iterator
* Uses `parentDir` for going backwards
* When going forwards, first `splitDrive`, yield the drive field, and
then iterate over path field as normal
* splitFile
* Make sure path parsing stops at end of drive component
* createDir
* Fixed by skipping drive part before creating directories
* Alternative implementation: use `parentDirs` iterator instead of
iterating over characters
* Consequence is that it will try to create the root directory
* isRootDir
* Changed to treat UNC drive alone as root (e.g. "//?/c:" is root)
* This change prevents the empty string being yielded by the
`parentDirs` iterator with `fromRoot = false`
* Internal `sameRoot`
* The "root" refers to the drive, so `splitDrive` can be used here
This adds UNC path support to all procs that could use it in std/os. I
don't think any more work has to be done to support UNC paths. For the
future, I believe the path handling code can be refactored due to
duplicate code. There are multiple ways of manipulating paths, such as
manually searching string for path separator and also having a path
normalizer (pathnorm.nim). If all path manipulation used `pathnorm.nim`,
and path component splitting used `parentDirs` iterator, then a lot of
code could be removed.
Tests
---
Added test file for `pathnorm.nim` and `ntpath.nim`.
`pathnorm.normalizePath` has no tests, so I'm adding a few unit tests.
`ntpath.nim` contains tests copied from Python's test suite.
Added integration tests to `tos.nim` that tests UNC paths.
Removed incorrect `relativePath` runnableExamples from being tested on Windows:
---
`relativePath("/Users///me/bar//z.nim", "//Users/", '/') == "me/bar/z.nim"`
This is incorrect on Windows because the `/` and `//` are not the same
root. `/` (or `\`) is expanded to the drive in the current working
directory (e.g. `C:\`). `//` (or `\\`), however, are the first two
characters of a UNC path. The following holds true for normal Windows
installations:
* `dirExists("/Users") != dirExists("//Users")`
* `dirExists("\\Users") != dirExists("\\\\Users")`
Fixes#19103
Questions:
---
* Should the `splitDrive` proc be in `os.nim` instead with copyright
notice above the proc?
* Is it fine to put most of the new tests into the `runnableExamples`
section of the procs in std/os?

* Move runnableExamples tests in os.nim to tos.nim
* tests/topt_no_cursor: Change from using splitFile to splitDrive
`splitFile` can no longer be used in the test, because it generates
different ARC code on Windows and Linux. This replaces `splitFile` with
`splitDrive`, because it generates same ARC code on Windows and Linux,
and returns a tuple. I assume the test wants a proc that returns a
tuple.

- Added optional `options` argument to `copyFile`, `copyFileToDir`, and

symlinks point to).
- `copyDir` and `copyDirWithPermissions` copy symlinks as symlinks (instead of
skipping them as it was before).
- `moveFile` and `moveDir` move symlinks as symlinks (instead of skipping them
sometimes as it was before).
- Added optional `followSymlinks` argument to `setFilePermissions`.
