I think this completes commit 50feca550eed7828198b7c0fc5f0e5ddc863313d.
Now result should be handled correctly both for systems that
support EAI_NODATA but returns EAI_NONAME (as my Ubuntu 9.x)
and systems that doesn't support EAI_NODATA at all.

We were creating the name resolution context as a child of lp_ctx,
which meant when we gave up on a connection the timer on name
resolution kept running, and when it timed out the callback crashed as
the socket was already removed.

When tracking down complex connection problems its useful knowing what
name lookups failed.

Also including the supporting changes required to pass make test

A number of heimdal functions and constants have changed since we last
imported a tree (for the better, but inconvenient for us).

FreeBSD has explicitly deprecated EAI_NODATA as a return value from
getaddrinfo by removing it from netdb.h.  On systems that don't have
EAI_NODATA, EAI_NONAME should be used instead.
