The second buffer was previously used when calling `fs_is_dir` explicity, but it has become from obsolete from #4657 by using the flag `FILE_ATTRIBUTE_DIRECTORY` instead.
Extract `windows_format_system_message` and allocate appropriate buffer for the formatted system error messages, so messages of any length can be displayed.
The flag `FORMAT_MESSAGE_ALLOCATE_BUFFER` is used so `FormatMessageW` allocates the buffer which must later be freed with `LocalFree`.
The flag `FORMAT_MESSAGE_MAX_WIDTH_MASK` is also added so the formatted message will not contain any line breaks at the end, which would make log messages less readable.
Reference: https://learn.microsoft.com/en-us/windows/win32/api/winbase/nf-winbase-formatmessagew
Converting multi-byte (UTF-8) to wide-char (UTF-16) take 1-4 bytes from the input and transforms them to 1-2 wide-chars, so having `char` and `WCHAR` buffers with equal lengths should mean that this function can't fail due to insufficient buffer sizes, unless a path that's already too long for Windows is being used internally.
Other errors are also not expected, as those would indicate programming errors like wrong arguments being passed.
The maximum length for paths in the Win32 API is 260 characters. This limitation can be lifted in Windows 10, but it must be done explicitly (opt-in) both in the Windows Registry by the user and in the application's manifest by us.

5942: Support unicode with ExcHndl, use upstream module offsets, handle errors r=def- a=Robyt3
Update Dr. Mingw (ExcHndl) to 0.9.8.
Use the new `ExcHndlSetLogFileNameW` function to set the exception log file name using wide characters, to support paths containing unicode.
It's not necessary to call `ExcHndlInit` explicitly after loading `exchndl.dll`, as the `DllMain` will already initialize the exception handler when the DLL is loaded. Module offsets are supported by upstream ExcHndl now, so we don't need to provide our own version that supplies the module offset to `ExcHndlInit` anymore. Upstream ExcHndl will also resolve the source code lines for addresses automatically, when the executable is build with debug information.
Handle the cases that the exception handling module cannot be loaded and that the `ExcHndlSetLogFileNameW` function cannot be found in the module.
Update `scripts/parse_drmingw.sh`:
- Parse both old and new module offsets.
- Use tabs instead of spaces consistently.
- Reset the ANSI color after printing colored messages.
Closes#5877.

- Parse both old and new module offsets.
- Use tabs instead of spaces consistently.
- Reset the ANSI color after printing colored messages.
- Retrieve version information of `kernel32.dll` without providing a fixed path to the Windows directory, to handle the case that Windows is not installed in the default location `C:\Windows`. This works because `GetFileVersionInfoSizeW` and `GetFileVersionInfoW` use the search sequence defined by `LoadLibrary`, so they will find the DLL without the path explicitly being specified. The version is retrieved from `kernel32.dll` instead of `user32.dll`, as the former is more commonly used for this purpose.
- Use the unicode (wide character) functions consistently instead of the ANSI functions.
- Use the correct format specifier `%hu` for `unsigned short` (i.e. `WORD` in the Windows API).

Update the `str_skip_to_whitespace(_const)` functions according to their documentation, which already stated that `\r` was also considered as whitespace.
This changes `str_comp_filenames` so it sorts filenames case insensitive while also comparing digits characters as numbers.
This makes filename sorting consistent with the behavior in Windows Explorer.
- Change argument and return value to `const char *`, as the string is not modified by this function.
- Use our own `str_isspace` instead of standard library `isspace`.
- Always trim leading whitespace to correctly handle inputs with leading whitespace.
For more consistent usage of the Windows API. `_wgetcwd` seems to be a wrapper around `GetCurrentDirectoryW` anyway, at least in the [Wine API](https://source.winehq.org/ident?_i=_wgetcwd).
Pass the correct size of the wide char buffer instead of passing the size of the output parameter buffer.
Remove a nullptr check. The argument should never be null and we don't check for null arguments anywhere else.
For more consistent usage of the Windows API. `_wchdir` seems to be a wrapper around `SetCurrentDirectoryW` anyway, at least in the [Wine API](https://source.winehq.org/ident?_i=_wchdir).
For more consistent usage of the Windows API. `_wmkdir` seems to be a wrapper around `CreateDirectoryW` anyway, at least in the [Wine API](https://source.winehq.org/ident?_i=_wmkdir).
Previously, the socket addresses were truncated as the `msg_namelen`
field is both input **and** output: After receiving an IPv4 packet, the
socket address field would be too short for an IPv6 address.

On Windows, the check was incorrectly using logical or instead of bitwise or. Checking for the flag `FILE_ATTRIBUTE_REPARSE_POINT` is not necessary, as the `FILE_ATTRIBUTE_DIRECTORY` will correctly be set when the target of a symbolic link is a directory. This otherwise causes symbolic links to files to be incorrectly handled as directories.
On Linux, the minor performance optimization of using `entry->d_type` is reverted and `fs_is_dir` is used instead. This internally uses `stat`, which correctly returns the attributes for the symbolic link targets.
5205: Allow multiple addresses per server in the serverbrowser r=def- a=heinrich5991
Support is incomplete for `leak_ip_address_to_all_servers` (will only
ping the first address of each server) and for the `leak_ip` setting
(which will also only ping the first address of each server).
Fixes#5158.

- `io_read_all` reads all bytes from a file handle into a new buffer. It should only need one allocation per file in cases where the actual file size matches the expected file size. Otherwise it falls back to doubling the buffer size if the actual file size is larger than expected to avoid TOCTOU problems.
- `io_read_all_str` reads all bytes from a file handle into a new buffer and also ensures that the buffer is null-terminated and contains no other null-characters.
- `mem_has_null` is a utility used by `io_read_all_str` to ensure that no null-characters exist in the bytes read from the file.
It didn't have a clear role, it just acted as a distinguisher between
two functions with the same name.
Rename `tw::time_get` to `time_get_nanoseconds` and delete the old
`time_get_nanoseconds`. Move `CCmdlineFix` and the typed
`net_socket_read_wait` function to the global namespace.
This makes the "black console window" less important on Windows (or
anywhere else, for that matter), lets you see logs from other threads in
the f1 console, and removes the distinction between `IConsole::Print`
and `dbg_msg`.

Previously, only Linux used an internal buffer (for optimized
receiving). Now all OSs use an internal buffer so that the call to
`net_udp_recv` behaves the same on all platforms.

- Empty buffers using `io_flush` before calling the OS function for
syncing the file to disk.
- Fix error return of `io_sync` on Windows.
- Don't indiscriminately flush all files on close.
- Add a test that `io_sync` can return without error.
I'm wondering if this helps. Overhead exists, but is not that much (on
my system): 333 ms for initialization instead of 311 ms
If we only want to do this for files written to, then we need to keep
track of how the file was opened.
