Filters are tested in order that last registered filter is tested first. First 
match stop further tests.

Currently one would have to unregister filters before calling grub_file_open()
and reregister them afterwards. However this can mix up filters order. Not 
a best option.

I was thinking about something like:
grub_file_open("name", NO_XFILTER|NO_YFILTER);
grub_file_open("name",NO_ALL);
to allow selectable filters or fopen() style maybe.

And a priority based filter registration if there is a need for that.
