Seem to have fixed dirbuf allocation.

Browse Source 
Dirbuf allocation was broken, fixed it.
Added more comments on reading directories.

Issues: fs0 ought to check buf address for sys_readdir(). Currently
test0 is passing an area on its stack and fs0 is writing the data to its own
address space (i.e. an area on its own stack.)
