Don't build mdnssd



This was enabled for Linux only, but Linux users should use Avahi,
which is present on most modern distributions, and implements mDNS
functionality.

// which is at its most expensive and least useful in cases where we know in advance that the names match
// Note: The dominant use of IdenticalResourceRecord is from ProcessQuery(), handling known-answer lists. In this case
// it's common to have a whole bunch or records with exactly the same name (e.g. "_http._tcp.local") but different RDATA.

// used to waste a lot of CPU time verifying that the names match, only then to find that the RDATA is different.
// We observed mDNSResponder spending 30% of its total CPU time on this single task alone.
// By swapping the checks so that we check the RDATA first, we can quickly detect when it's different
// (99% of the time) and then bail out before we waste time on the expensive SameDomainName() check.
