As an idea for a feature, it could be good to have an fadvise variant
taking a file handle or file descriptor. A handle is good to be sure of
advising about the intended thing in case of any file renaming.
I'd suggest different function names, maybe fadvise_fh() and
fadvise_fd(). The latter might be nearly your existing xs func.
I know some modules like to take file name and file handle in one
function by testing for ref-ness, but it's usually bad to enquire into
the nature of an arg since that can go wrong on overloads such as
Path::Class or a number class. (The supposed convenience of a single
func becomes the inconvenience of not transparent to overloads ...)
