The only difference, compared to the pre-existing code, is that symlink
creation now triggers fsnotify_create. This was a bug in the debugfs
code, since for example vfs_symlink does call fsnotify_create.

libfs.c has many functions that are useful to implement dentry and inode
operations, but not many at the filesystem level. Start adding file
creation wrappers, the simplest returns an anonymous inode.
There is no functional change intended.

aa_mk_null_file is using simple_pin_fs/simple_release_fs with local
variables as arguments, for what would amount to a simple
vfs_kern_mount/mntput pair if everything was inlined. Just use
the normal filesystem API since the reference counting is not needed
here.

We will augment this family of functions with inode management. To avoid
littering include/linux/fs.h and fs/libfs.c, move them to a separate header,
with a Kconfig symbol to enable them.
