fuse: update fuse_kernel.h to version 23
The following changes were made upstream:
- add FUSE_WRITEBACK_CACHE
- add time_gran to fuse_init_out
- add reserved space to fuse_init_out
- add FATTR_CTIME
- add ctime and ctimensec to fuse_setattr_in
- add FUSE_RENAME2 request
- add FUSE_NO_OPEN_SUPPORT flag
Including these changes will make it easier to backport support for
lseek().
Because the fuse_init_out structure changed its size, older versions of
FUSE would fail initializing. When an older version of FUSE is detected,
the fuse_init_out structure is reduced to the previous size. This is
harmless, as the attributes that are not passed, are not used for
earlier versions anyway.
