Opens a file for reading. The result is a #GFileInputStream that
can be used to read the contents of the file.
If cancellable is not null, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error gio.types.IOErrorEnum.Cancelled will be returned.
If the file does not exist, the gio.types.IOErrorEnum.NotFound error will be
returned. If the file is a directory, the gio.types.IOErrorEnum.IsDirectory
error will be returned. Other errors are possible too, and depend
on what kind of filesystem the file is on.
