Rework the design and implementation of database connection pooling in the Data
Manager Library. Provide a callback mechanism for the calling application to
manage its own connection pool. This should include a mechanism for returning a
"Connection not available" status to the Data Manager so that it will know that
it needs to wait until a connection is available. The Data Manager should
generally use one connection per operation, though if the operation has several
steps it could re-use the same connection in more than one step if it's safe to
do so.
