... in filenames. Replace the existing Unicode conversion functions with UTF conversion functions from js that he relicensed MIT for us. Put the UTF conversion functions in a private but shared code location so that they can be accessed throughout the kernel. Right now we only provide functions to convert between UTF-8 and UTF-16. At some point we should also add functions to convert between UTF-8 and UTF-32 and UTF-16 and UTF-32 but these aren't needed by exfat. Remove the old Unicode conversion functions from exfat as they assumed UCS-2 characters and don't work with UTF-16 used by exfat. Rename most variables with the term length with code unit where code units are intended. The term length, when used, means length in bytes while code units represent either a full 2-byte UTF-16 character or half a 4-byte surrogate pair.
