Robert Müller 6501ae9b9d Add checks for remaining WideCharToMultiByte usages in system
Converting wide-char (UTF-16) to multi-byte (UTF-8) takes 1-2 wide-chars from the input and transforms them to 1-4 bytes, so having `char` and `WCHAR` buffers with equal static lengths means that this function can fail due to insufficient buffer sizes when the user has folder or files with very long names (many unicode codepoints).
Therefore checks are added that allow only the error `ERROR_INSUFFICIENT_BUFFER` when `WideCharToMultiByte` fails, which is expected on very long paths, as these would also lead to further errors later in the code. The respective functions will now fail with a return and ignore files that have too long names.
This could only completely be fixed using dynamically sized buffers for all paths, which seems like too much work and overhead.
Other errors are not expected and hence caught by the assertions, as those would indicate programming errors like wrong arguments being passed.

Robert Müller 6c30fb6f5a Remove duplicate buffer from fs_listdir functions
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.

Robert Müller 8bde109acb Use dynamic size for formatted Windows system messages
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.

Robert Müller a1c1a8f972 Add assertions for all MultiByteToWideChar usages in system
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.

Robert Müller c4cf26ea81 Replace atol usages with str_toint, as type is int anyway
As `atol` does not provide any way to detect errors and can cause undefined behavior on errors, i.e. when the result cannot be represented as a `long`.

The `atol` function was only used in `priv_net_extract` for parsing the port, which is an `int` and not a `long`, so the existing `str_toint` is used instead.

Merge #5942
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.

Robert Müller c68841a733 Ensure Windows DDE conversations are finished in open_link
Use `ShellExecuteExW` instead of `ShellExecuteW` to pass the additional flag `SEE_MASK_NOASYNC`. This should ensure that DDE (Dynamic data exchange) conversations are finished before the function returns, as it would otherwise be necessary to manually pump messages on the calling thread. DDE conversations may be initiated when shell extensions are loaded via `ShellExecute`. Failing to answer the DDE messages will block the calling UI thread and may cause a dead-lock.

The flag `SEE_MASK_FLAG_NO_UI` is used to prevent native error message popups when the link/file cannot be opened.

Additionally, the `ShellExecute` verb is changed from `"open"` to `NULL`, which will cause the default shell handler to be used instead, as the `"open"` verb may not be available for all targets. Though for most targets it will be the default verb anyway.

Robert Müller 1697231916 Handle non-default Windows directory in os_version_str
- 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).

Robert Müller 61f763ff2c Use GetCurrentDirectoryW instead of _wgetcwd
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.

Robert Müller ec55212c52 Fix symlink handling of fs_listdir
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.

Robert Müller c7fb013607 Add io_read_all, io_read_all_str and mem_has_null:
- `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.

heinrich5991 b3a3604c36 Remove namespace tw
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.

Not sure if this is preferred

We could also try switching to std::mutex
