[hail] CLD conversion to TCP lands in git

I just pushed the CLD protocol change (UDP -> TCP) to hail.git[1].  See 
the original post[2] for more details.  It seems pretty solid from my 
beating on it, but it's still raw code.

The focus will be on hammering out the kinks in this switch over the 
next 7-10 days, so expect some breakage and churn during that time.

In particular, while tabled /should/ work, as the API has only seen 
minor changes, it will need a good stress test before I regain 
confidence in it.  There was also an unrelated-to-CLD API change in 
libhail that requires a small tabled tweak[3], that will be attended-to 
this week.
