[Buildroot] [PATCH 2/3] package/mdnsd: install libmdnsd to staging/

[Joachim Wiberg]

The mdnsd project has always been both a daemon and a library you can
link to your own application.  With v1.0 a major bug (requiremnt on an
internal header, config.h) has been removed, enabling installation of
.a and .h files to staging.

[Buildroot] [PATCH 3/3] support/testing: mdnsd: new runtime test

[Joachim Wiberg]

Boot an armv5 image running the mdnsd responder alongside the mquery
client, then check that service discovery works: mquery browses for the
bundled _http._tcp service and mdnsd, on the same host, answers over the
loopback of the eth0 multicast group.
