Colin Vidal 4096f27130 add support for multiple EDE ... Extended DNS error mechanism (EDE) enables to have several EDE raised during a DNS resolution (typically, a DNSSEC query will do multiple fetches which each of them can have an error). Add support to up to 3 EDE errors in an DNS response. If duplicates occur (two EDEs with the same code, the extra text is not compared), only the first one will be part of the DNS answer. Because the maximum number of EDE is statically fixed, `ns_client_t` object own a static vector of `DNS_DE_MAX_ERRORS` (instead of a linked list, for instance). The array can be fully filled (all slots point to an allocated `dns_ednsopt_t` object) or partially filled (or empty). In such case, the first NULL slot means there is no more EDE objects.		2025-01-22 21:07:44 +01:00
