In a transaction, on a Stmt.Query error, it was possible for a
connection to be added to a db's freelist twice. Should use
the local releaseConn function instead.
Thanks to Gwenael Treguier for the failing test.
Also in this CL: propagate driver errors through releaseConn
into *DB.putConn, which conditionally ignores the freelist
addition if the driver signaled ErrBadConn, introduced in a
previous CL.

-- add driver.Value type and documentation,
convert from interface{} to Value where
appropriate.
-- don't say "subset" anywhere,
-- SubsetValuer -> Valuer
-- SubsetValue -> Value
-- IsParameterSubsetType -> IsValue
-- IsScanSubsetType -> IsScanValue
Fixes#2842

If the database driver supports the Execer interface but returns
ErrSkip, calling Exec on a transaction was returning the error instead
of using the slow path.
