This patch adds a roll_trans parameter to all attribute routines
that may roll a transaction. Calling functions may pass true to
roll transactions as normal, or false to hold them.
This patch is temporary and will be removed later when all code
paths have been made to pass a false value. The temporary boolean
assists us to introduce changes across multiple smaller patches instead
of handling all affected code paths in one large patch.
