Carter Kozak 272ea1fa83 Fixed NPE PoolingAsyncClientConnectionManager
PoolingAsyncClientConnectionManager.validateAfterInactivity causes
an NPE when PoolEntries are initially created with no Connection.

Added logic to avoid checking the connection on every pool
checkout similar to the blocking pool.

Added an connection.isOpen check to http1.x connections leased
from the pool, although I'm unsure if it's at all effective.
