Message:

Use proper sizes for buffers holding conversions from/to UTF-16 LFN's

FAT uses UTF-16 for encoding long file names. HelenOS needs to convert
these strings into and from its native UTF-8 encoding. The size of the
UTF-8 buffer in bytes needs to be at least 4 times the number of
characters in a LFN.
