Fix bug #81068: Fix possible use-after-free in realpath_cache_clean()

If ZTS is enabled, this can cause cwd_globals_ctor() to be called
multiple times, each with a freshly allocated virtual_cwd_globals
instance. At shutdown time however, cwd_globals_dtor() will call
realpath_cache_clean(), which then possibly cleans up the same
realpath_cache instance more than once. Using AddressSanitzer, this
shows up as a heap use-after-free.

To avoid this, add a helper function to do the actual work on one
instance of a realpath_cache, and call it both from cwd_globals_dtor()
and realpath_cache_clean(). The former uses the virtual_cwd_globals
parameter passed in via the destructor, the latter uses the CWDG()
macro.

Fix #80960: opendir() warning wrong info when failed on Windows

Firstly, we must not forget to set appropriate error codes for "manual"
checks in `virtual_file_ex()`.

Secondly, we must not call `php_error_docref2()` for warnings regarding
unary functions; thus, we introduce `php_win32_docref1_from_error()`.

Closes GH-6872.

While that is basically correct, some reparse points may point to
inaccessible system folders (e.g. `IO_REPARSE_TAG_DEDUP` points to
"\System Volume Information"). Since we don't know details about
arbitrary reparse points, and are mainly interested in nested symlinks,
we take a step back, and only resolve `IO_REPARSE_TAG_SYMLINK` for now.

Close GH-6354.

Fix #79806: realpath() erroneously resolves link to link

`zend_llist_add_element()` and `zend_llist_prepend_element()` now
explicitly expect a *const* pointer.

We use the macro `ZEND_VOIDP()` instead of a `(void*)` cast to suppress
C4090; this should prevent accidential removal of the cast by
clarifying the intention, and makes it easier to remove the casts if
the issue[1] will be resolved sometime.

Fix #78220: Can't access OneDrive folder

As of Windows 1903, when the OneDrive on-demand feature is enabled, the
OneDrive folder is reported as reparse point by `FindFirstFile()`, but
trying to get information about the reparse point using
`DeviceIoControl()` fails with `ERROR_NOT_A_REPARSE_POINT`. We work
around this problem by falling back to `GetFileInformationByHandle()`
if that happens, but only if the reparse point is reported as cloud
reparse point, and only if PHP is running on Windows 1903 or later.

The patch has been developed in collaboration with ab@php.net.

We should keep an eye on the somewhat quirky OneDrive behavior, since
it might change again in a future Windows release.

Remove local variables

This patch removes the so called local variables defined per
file basis for certain editors to properly show tab width, and
similar settings. These are mainly used by Vim and Emacs editors
yet with recent changes the once working definitions don't work
anymore in Vim without custom plugins or additional configuration.
Neither are these settings synced across the PHP code base.

A simpler and better approach is EditorConfig and fixing code
using some code style fixing tools in the future instead.

This patch also removes the so called modelines for Vim. Modelines
allow Vim editor specifically to set some editor configuration such as
syntax highlighting, indentation style and tab width to be set in the
first line or the last 5 lines per file basis. Since the php test
files have syntax highlighting already set in most editors properly and
EditorConfig takes care of the indentation settings, this patch removes
these as well for the Vim 6.0 and newer versions.

With the removal of local variables for certain editors such as
Emacs and Vim, the footer is also probably not needed anymore when
creating extensions using ext_skel.php script.

Additionally, Vim modelines for setting php syntax and some editor
settings has been removed from some *.phpt files. All these are
mostly not relevant for phpt files neither work properly in the
middle of the file.

Fixed bug #77317 __DIR__, __FILE__, realpath() reveal physical path for subst virtual drive

Keep compatibility with 7.2 and below which better comply with
realpath(3). This might have been fixable another way, say by checking
of QueryDosDevice or alike, sadly that comes with a huge performance
impact. The new internal realpath API is kept available so is
usable when bind or network mount or other OS specific realpath
variants are needed. If not used by default, a userspace function for
this specific case might be considered to be offered in next minor.
