allowing application to set transaction as PA unsafe

Browse Source 
* Removed transaction::p_unsafe_ member
* Changed transaction::pa_unsafe(bool) to modify flags member directly
* Modified transaction.cpp to use transaction.pa_unsafe(bool) rather than
  directly changing transaction's flag
* added method mark_transaction_pa_unsafe() for client_state,
  application will use this
