[ Upstream commit fa4320cefb8537a70cc28c55d311a1f569697cd3 ] Like other filesystem does, we introduce a new file f2fs.h in path of include/uapi/linux/, and move f2fs-specified ioctl interface definitions to that file, after then, in order to use those definitions, userspace developer only need to include the new header file rather than copy & paste definitions from fs/f2fs/f2fs.h.
