The previous implementation expected to work with a context object that
contained a field `conn` that represented a valid database connection.
However, this required the caller to manage the connection's lifecycle
(close, renew, etc.). Now we expect to receive a context object that
provides a `withConn` procedure or template that accepts a statement
block and provides a `conn` variable to that code block. For example:
createRecord(db: DbContext): Record =
# withConn must be defined for DbContext
db.withConn:
# conn must be injected into the statement block context
conn.exec(sql("INSERT INTO..."))
In addition, this change provides a connection pooling mechanism
(`DbConnPool`) as a default implementation for this hypothetical
DbContext. There is also a new function `initPool` that will create an
DbConnPool instance.
Callers of this library can modify their DbContext objects to extend
DbConnPool or simply be a type alias of DbConnPool.
