Add odb::connection class
This abstract class represents a connection to the database. One can
use it to start a transaction or to execute a native statement out
of a transaction.
Before we had concrete connection classes in the database runtime
libraries (e.g., odb::mysql::connection). Now these classes derive
from odb::connection.
