-BUGS
-       Needing to include int random_seed; and int simulate_power_failure = 0; in any main program using yaffsfs.h
-       bug with opening a file with a name of 1,000,000 char long with no errors.
-       bug with unlinking a file with 1,000,000 get the error ENOENT but should be geting ENAMETOOLONG. 
-       
-       FIXED-ENOSPC error in programs test_yaffs_open_ENOTDIR and test_yaffs_open_ENOENT.
-       FIXED-ENOENT been returned by yaffs_read but the handle is good and the yaffs_open function does not return an error.
