strlist: can be unique or not, add printf functions
Make it a selectable option at allocation time if a strlist should contain only unique strings or not. If not, we omit the hash table and strlist_find() will not do anything. Add printf()-style functions to a strlist. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
