my_uuid2str() has an off-by-one that results in the hyphens ending up two nibbles to the right of where they should be in the UUID.

How to repeat:
select uuid();

compare uuid() to that generated by 5.0 or 5.1 mysqld, or in fact any UUID. try to decode with random uuid tool.

Suggested fix:
void my_uuid2str(const uchar *guid, char *s)
  if(i == 3 || i == 5 || i == 7 || i == 9)
