Hi Ivaylo.

Trivial notes:

The function name change in dbcdc.c from
uuid_uuid_from_string to dcd_uuid_from_string
seems unnecessary.

If you are going to change the name, please
also reindent the multi-line statements to the
open parenthesis as the rest of the file has
that style.

The 2nd and 3rd lines of dcd_uuid_from_string
should be moved 1 left.

here too.

It also appears as if these could set status
to the from_string return value and error-out
when non-zero.
