There was a confusion between these: this commit tries to disambiguate them. - Scope can be computed from the address itself. - Scope id is scope dependent: it is currently defined as 1-based local interface index for link-local scoped addresses, and as a site index(?) for (obsolete) site-local addresses. Linux only supports it for link-local addresses. The URL parser properly parses a scope id as an interface index, but stores it in a field named "scope": confusion. The field has been renamed into "scope_id". Curl_if2ip() used the scope id as it was a scope. This caused failures to bind to an interface. Scope is now computed from the addresses and Curl_if2ip() matches them. If redundantly specified in the URL, scope id is check for mismatch with the interface index. This commit should fix SF bug #1451.
