Robert Müller 02a7913121 Sort filenames case insensitive with str_comp_filenames, add tests
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.

Robert Müller ce145cfa4e Improve str_trim_words and add tests
- 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.

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.

`time_get_nanoseconds`. Move `CCmdlineFix` and the typed
`net_socket_read_wait` function to the global namespace.

def 790c1cc0aa Switch new players to DDNet config dir, support Teeworlds as fallback
This way new players will get DDNet directory, old ones can switch
directory if they want, or keep using the old one.

If we ever enforce a switch in a future version, this will make it
easier since older DDNet versions will also support the DDNet directory
already.

If we only want to do this for files written to, then we need to keep

4111: Fix filesystem/IO with unicode filenames on windows r=def- a=Robyt3

It was previously not possible to load a map or really any file with a filename containing unicode, e.g. german umlauts.

Now all filenames are converted from multibyte to widechar on windows, and the correct functions and structs (with the `W` suffix) are used consistently.

Some changes are made to synchronize ddnet's implementation with upstream (once https://github.com/teeworlds/teeworlds/pull/2936 has been merged there):
- The unused and not working `IOFLAG_RANDOM` is removed (on upstream ddnet's `IOFLAG_APPEND` is added instead).
- The `fs_listdir_info` function is renamed to `fs_listdir_fileinfo` and now using the parameter object `CFsFileInfo` that contains the filename, modified date and creation date, making it easier to add more properties in the future. `FS_LISTDIR_INFO_CALLBACK` is renamed to `FS_LISTDIR_CALLBACK_FILEINFO`.

heinrich5991 fb27b83d79 Add function to remove directories
Add tests. Unify behavior of `fs_remove` across operating systems to
only remove files, not directories. Previously on Linux, it would also
delete directories.

def d9804f5142 str_format: always return length of written string
Quoting the man page of vsnprintf:

RETURN VALUE
  Upon successful return, these functions  return  the  number  of  characters  printed
  (excluding the null byte used to end output to strings).

  The functions snprintf() and vsnprintf() do not write more than size bytes (including
  the terminating null byte ('\0')).  If the output was truncated due  to  this  limit,
  then  the  return  value  is the number of characters (excluding the terminating null
  byte) which would have been written to the final string  if  enough  space  had  been
  available.  Thus, a return value of size or more means that the output was truncated.
  (See also below under NOTES.)

  If an output error is encountered, a negative value is returned.

[...]

  The glibc implementation of the functions snprintf() and vsnprintf() conforms to  the
  C99  standard,  that  is, behaves as described above, since glibc version 2.1.  Until
  glibc 2.0.6, they would return -1 when the output was truncated.
