When registering audio cards for the handsfree and gateway roles we
need a way for our users to differentiate between both to decide which
of them they start using for their purpose.

New subject: [PATCH 2/2 v2] hfp_ag_bluez5: register audio card
To let others (PulseAudio) be notified when a handsfree device is
connected with us and can be used for audio routing we need to
expose this by registering a audio card with the correct type.
For now there is no need to provide a card driver and we just stick
to what the core provides.

The comment in commit 9332299b indicates that a dup() was needed to
properly detect HUP events. Can you double check that this change is
indeed correct?

On HFP 1.6 and 1.7, the audio should not be triggered until SLC is
established. Whats your plan to ensure that PulseAudio does not start
using the audio device until then? FYI, the earlier attempt to add AG
support had src/emulator.c make the ofono_handsfree_card_register() call
at the appropriate time.
