Provision complete callback is handled in provision failure case.
If link closed received abruptly with reason success, triggered
provision complete callback. Removed session timeout and session
free as they are handled in pb_adv_unreg.
5.3.2 of Mesh Profile Bluetooth specification:
To open a link, the provisioner shall start the link establishment
timer, set to 60 seconds, and then shall start sending Link Open
messages.
On timeout, close indication will be sent. Provisioner cancels the
Link Establishment timer, when the link is open i.e. in pb_adv_tx().
In certain circumstances, reception of PB-ADV messages may trigger
session close. This rearrange ACKs new verified messages before
performing call-back to avoid situations where the session no longer
exists after the message has been handled.
This caused static analysis errors during provisioning, which are now
addressed.
If pb_session is freed in timeout, close indication will not be sent.
pb_session is freed in pb_adv_unreg() and hence removed from tx_timeout.
Added acceptor_free() in acp_prov_close() to ensure pb_session is freed.
For initiator, transaction number starts from 0x00 where as for acceptor
transaction number starts from 0x80. Since transaction number is
pre-incremented and sent in every packet, initialize it with 0xFF for
initiator and 0x7F for acceptor.
Provisioning packets are defined in the specification
as packed big endian structures. Instead of specifying
an octet array, we now use struct matching the spec.
Originally found in prov.c, this file implements the PB-ADV
provisioning transport. It may be used by either the
Acceptor or the Initiator side of the Provisioning procedure,
but only one session may be active at a time.
