Instead of returning the number of bytes written, which are platform specific, return `true` on success and `false` on failure, so no platform specific code is required when checking the result.
Use `bytes_be_to_uint` and `uint_to_bytes_be` instead.
As casting between `int` and `unsigned` preserves the bit representation of the value, it's not necessary to apply additional tricks to convert between `char` arrays and `int`.
Using `str_format` without format arguments is equivalent to `str_copy`, but using the latter is more efficient and readable.
As `str_format` also returns the result `str_utf8_fix_truncation`, i.e. the potentially truncated string length, the return value is also added to `str_copy` so existing invocations don't need to be adjusted.
6299: Show error message when downloaded map cannot be saved r=def- a=Robyt3
Check if deleting the old map file or renaming the temporary downloaded map fails. If so, show an error message which indicates that the user should delete the map file manually.
Sometimes downloaded map files seem to end up with wrong permissions, ownership or with read-only flag set, which makes the client unable to delete them.

This function removes the registry keys that are created with `shell_register_protocol` and `shell_register_extension`.
According to the Microsoft documentation, only the keys for the program IDs should be deleted.
The keys that associate the file extensions with the program IDs should be kept, as Windows will automatically ignore the value if the program ID does not exist.
See: https://learn.microsoft.com/en-us/windows/win32/shell/fa-file-types#deleting-registry-information-during-uninstallation
The `shell_update` function notifies the system when the shell needs to be updated due to a changed protocol or file association.
An output parameter is added to the `shell_register_protocol` and `shell_register_extension` functions, to determine whether the shell needs to be updated after calling the functions.
We only check whether the application path and program association were changed, instead of checking whether any key or value was changed, as this reduces the amount of necessary checks and we assume that the other values are not externally changed.
Because updating the shell is a potentially expensive operation, this should only be done when necessary and only once after registering all protocols and extensions.
This function register a file extension on Windows by creating the necessary registry keys and values.
The file extension is only registered for the current user in the registry key `HKEY_CURRENT_USER\SOFTWARE\Classes`, so admin privileges are not required.
Windows does not allow changing the default file extension handler programatically. When the user opens a file for which a new file extension handler exists, a dialog is shown that allows the user to change the default handler.
This function registers a protocol handler on Windows by creating the necessary registry keys and values.
The handler is only registered for the current user in the registry key `HKEY_CURRENT_USER\SOFTWARE\Classes`, so admin privileges are not required.

The functions `str_utf8_skeleton_begin` and `str_utf8_skeleton_next` and the `struct SKELETON` are only used internally, so they don't need to be exported.
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.
- `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`.
