Jack Christensen 743b98b298 Name PG types as words 
Though this doesn't follow Go naming conventions exactly it makes names more
consistent with PostgreSQL and it is easier to read. For example, TIDOID becomes
TidOid. In addition this is one less breaking change in the move to V3.

Jack Christensen b1fc8109db Remove AF_INET fetching system 
Also remove old encode/decode inet/cidr code. This removed some functionality
from Rows.Values, but that entire system will soon change anyway.

konstantin 7f9373c7c0 Make ConnPool.Acquire() non blocking 
When there was an issue with DB server ConnPool.Acquire() used to block
until it heard back from the server or its OpenTimeout hit. If we had
OpenTimeout set to 3 secs, and there were X go routines trying to aquire a
connection in parallel, the very last go routine would receive timeout
error in X*OpenTimeout seconds because of the blocking nature of the
ConnPool.Acquire().

With this commit ConnPool.Acquire() is not blocking any more, and all
X requests will take about 1*OpenTimeout secs to fail.

John Barker a282d9df90 Cache connection properties in the pool 
This is a quick attempt to improve connection startup time by caching
the properties that are loaded when a connection is ready in the pool,
so that further connections don't incur this cost.

I'm not entirely convinced by the interface here, perhaps these 3 items
could live in their own type and that be passed around for clearer code,
but the idea works well.

Jack Christensen 20d22a67e3 Prevent deadlock on ConnPool.Acquire with Reset 
If no connections are available, and the pool is reset, there will
be no connections at all in the pool. So the pool needs to be able
to create a connection after waiting for a connection to be released.

Jack Christensen 93aa2b2e80 ConnPool.Begin retry logic checks connection IsAlive 
ErrDeadConn is returned when calling an already dead connection. But the initial failure returns the real error. So we check for IsAlive instead of ErrDeadConn.

Added test for ConnPool.Begin retry logic.
