libpri: Add control of inband audio progress indication ie to the SETUP_ACKNOWLEDGE message.
Added support to the libpri API to control the inband audio available progress indication ie on the SETUP_ACKNOWLEDGE message. * Added the progress indication ie progressmask value to the struct pri_event_setup_ack so the PRI_EVENT_SETUP_ACK event can indicate when a SETUP_ACKNOWLEDGE comes in with inband audio (ie dialtone). * Added pri_setup_ack() so when the SETUP_ACKNOWLEDGE message is sent it can indicate if inband audio is present (ie dialtone). This patch and a corresponding change in Asterisk work together to allow Asterisk to control the inband audio available progress indication ie on the SETUP_ACKNOWLEDGE message when dialtone is present.
