[CRIU] [PATCH 6/8] inotify: Add checkpoint/restore

[Cyrill Gorcunov]

To checkpoint notifiers we need help from kernel side,
thus FS_INOTIFY_GET_MARK ioctl code added.

Other than that

 - the inotify descriptors are collected into global inotify.img file
 - the inotify marks are collected into global inotify-wd.img
 - at restore time they are read and restored with help
   of inotify_init and inotify_add_watch calls
 - file owners are not yet supported, will be addressed in another patch
