James Hartig 6d336eccb1 Added LastStmtSent and use it to retry on errors if statement was not sent 
Previously, a failed connection could be put back in a pool and when the
next query was attempted it would fail immediately trying to prepare the
query or reset the deadline. It wasn't clear if the Query or Exec call
could safely be retried since there was no way to know where it failed.

You can now call LastQuerySent and if it returns false then you're
guaranteed that the last call to Query(Ex)/Exec(Ex) didn't get far enough
to attempt to send the query. The call can be retried with a new
connection.

This is used in the stdlib to return a ErrBadConn if a network error
occurred and the statement was not attempted.

Fixes #427

stdlib: fix race with Driver.configs in Open 
The Driver.configs map is protected by configMutex in
registerDriverConfig and unregisterDriverConfig, but not in Open. This
results in a race if Open is called while another goroutine is
registering/unregistering a DriverConfig.

Jackson Owens 14f1f2aa01 stdlib: allow nested database/sql/driver.Drivers 
database/sql/driver.Driver implementations can be nested, with each
layer adding additional functionality. If pgx/stdlib.Driver is wrapped
in another driver.Driver implementation, AcquireConn will error,
detecting that the *sql.DB's driver is not (directly) pgx.Driver.

It looks like it should be possible to support the current functionality
without requiring that the top-level Driver be pgx/stdlib.Driver, but
it requires using a global map of fakeTxConns instead of a per-Driver
map of fakeTxConns.

Is this reasonable?

Terin Stock 1a99c0e5c4 fix(stdlib): lock openFromConnPoolCount while using 
Locks the `openFromConnPoolCount` counter while formatting the driver
name and incrementing to avoid a data race of multiple goroutines
modifying the counter and registering the same name. `sql.Register`
panics if a driver name has already been registered.

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.
