    umdns: update to the version 2017-03-21
    
    This includes following changes:
    480d7bc Fix sending unicast questions on cache expire
    a0403cd Keep source sockaddr for every cached DNS record
    1478293 Fix code freeing cached non-A(AAA) records too early
    9f1cc22 Fix replying to "QU" questions received on unicast interface
    943bedb Fix reading port of incoming packets
    c725494 Use MCAST_PORT define for port 5353
    ce7e9e9 Use one define for DNS-Based Service Discovery service name
    e1bacef Drop entries cached for interface we're going to delete
    496aeba Fix comment typo in cache_gc_timer
    f89986b Fix refreshing cached A(AAA) records that expire
    
    Previous updates made umdns work as expected on startup but there were
    still many bugs. They were mostly related to runtime - cache management
    and requests + responses. E.g. umdns was never able to send question on
    DNS record expire. It was also ignoring all incoming unicast questions.
    
    Since these issues are quite serious it makes sense to backport this
    update to the stable branch.
