uuid_parse - convert an input UUID string into binary representation
int uuid_parse( char *in, uuid_t uu);
The uuid_parse function converts the UUID string given by in into
the binary representation. The input UUID is a string of the form
1b4e28ba-2fa1-11d2-883f-b9a761bde3fb (in printf(3) format
"%08x-%04x-%04x-%04x-%012x", 36 bytes plus the trailing '\0').
Upon successfully parsing the input string, 0 is returned, and the UUID is
stored in the location pointed to by uu, otherwise -1 is returned.
This library parses UUIDs compatible with OSF DCE 1.1, and hash based UUIDs V3
and V5 compatible with RFC-4122.
