Обсуждение: txid cleanup

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.

Yes, at least in CVS HEAD.

Applied with some further editorialization.

Aha, I had missed that.

Thanks for confirmation.
