- separate file_system_util into vfs functions (-> vfs/vfs_util) and file_system (avoids ugly fs_util namespace prefix) - get rid of non-portable O_BINARY_NP etc. flags - use standard O_WRONLY etc. flags instead of LIO_WRITE; but avoid the need for specifying O_CREAT|O_TRUNC - only open files for aio when O_DIRECT is specified (which 0ad does not) - avoids wasting time and security issues - return file descriptor directly instead of via output param - waio: safer FCB mechanism that avoids mixing descriptors between lowio and aio This was SVN commit r9550.
