/*
** This routine takes a user-entered UUID which might be in mixed
** case and might only be a prefix of the full UUID and converts it
** into the full-length UUID in canonical form.
**
** If the input is not a UUID or a UUID prefix, then try to resolve
** the name as a tag. If multiple tags match, pick the latest.
** If the input name matches "tag:*" then always resolve as a tag.
**
** If the input is not a tag, then try to match it as an ISO-8601 date
** string YYYY-MM-DD HH:MM:SS and pick the nearest check-in to that date.
** If the input is of the form "date:*" then always resolve the name as
** a date. The forms "utc:*" and "local:" are deprecated.
**
** Return 0 on success. Return 1 if the name cannot be resolved.
** Return 2 name is ambiguous.
