Link one file to another file
Creates a new link (directory entry) at newpath for the existing file at oldpath. In the
case of a relative oldpath, the path is interpreted relative to the directory associated
with file descriptor olddirfd instead of the current working directory and similiarly for
newpath and file descriptor newdirfd. In case flag is LinkatFlags::SymlinkFollow and
oldpath names a symoblic link, a new link for the target of the symbolic link is created.
If either olddirfd or newdirfd is None, AT_FDCWD is used respectively where oldpath
and/or newpath is then interpreted relative to the current working directory of the calling
process. If either oldpath or newpath is absolute, then dirfd is ignored.
