- Duplicate functionality files removed; - Refactoring of file handling functions; - Removed broken impliments. Gears (C + TinyGL): - Removed because it duplicates an existing example on Fasm and uses unsupported wrappers on the KOS API. KosJS: - Removed. The MuJS port is too old and not used anywhere. Support is not profitable. Backy: - Removed useless GCC version. Support is not profitable. DGen-SDL and SQLite3 - Fix after removing broken "dirent.h". Fridge: - Moving the KOS API wrapper to avoid compilation errors. Udis86, uARM and 8086tiny: - Fix after removing redundant "kos_LoadConsole.h". git-svn-id: svn://kolibrios.org@9952 a494cfbc-eb01-0410-851d-a64ba20cac60
