- Haiku is Unix-like, but it still doesn't use libnotify.
- Haiku comes with its own sets of definitions for certain long variables.
There's still a problem revolving around the variables, but I removed a
duplicate, conflicting definition on the Haiku platform.
- Changed some definition-related logic in detect.h, because the gcc compiler
in Haiku (version 8.3.0) complained about duplicate definitions. I chose to
use 'unknown' rather than an empty string on one occasion.
- Changed size of m_aLastSoundPlayed[CHAT_NUM] in
`src/game/client/components/chat.cpp` due to an undocumented/undiscovered bug
in Haiku.
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`.
