Aaron Schulz c1e1512698 rdbms: improve LoadBalancer connection pool reuse (ii) ... Make DBConnRef enforce the DB domain selected during its lifetime and allow more nested and successive use of the same connection handle via DBConnRef. This can avoid extra connections in some cases where getConnection()/getConnectionRef() is used. Also: * Reduce the number of connection pools arrays from six to two * Merge getLocalConnection()/getForeignConnection() into one method * Expand various related code comments Since LoadBalancer::getReadOnlyReason() no longer user the local domain but rather DOMAIN_ANY, it should not result in "USE" errors if the local domain does not have a database on the server. This version of the patch removes the unused reuseConnectionInternal() method (the method was previously added back to the patch by mistake).
