Per Tom comments, attached patch does following:

- Binary I/O support
- Use ActiveSnapshot instead of SerializableSnapshot
- Clarify function purposes
- remove dev targets from Makefile


There should not be any code depending on SerializableSnapshot,
if there is thats a bug that needs fixing.  Fix is easy - use
SERIALIZABLE transaction isolation level.

Also - either Tom or Jan has changed the code to allow
xmin == xmax.  Is such case really valid?  In _recv
code I followed the style, but I was just wondering.
