Bluetooth Socket API relies on having preregistered bluez sdp records for HSAG, HFAG, OPP & PBAP
that are mapped to rc chan 10, 11,12 & 19. Today HSAG and HFAG is routed to BRCM AG and are not
using BT socket API so for now we will need to support OPP and PBAP to enable 3rd party developer
apps running on BRCM Android.
To do this we will check the UUID for the requested service and mimic the SDP records of bluez
upon reception. See functions add_opush() and add_pbap() in sdptool.c for actual records
