This splits the handling of device changes and modem registration so
they can be uses separately.

New subject: [PATCH v4 2/5] hfp_hf_bluez5: Fix not creating modem during NewConnection
From: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com>
In case the UUIDs are not updated, as they are still being resolved, when
Paired property changes a modem will never be registered.
In order to fix this problem allow modems to be registered directly
during NewConnection.

New subject: [PATCH v4 3/5] hfp_hf_bluez5: Handle ServicesResolved signal
From: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com>
This adds handling for ServicesResolved signal which tells when BlueZ
is done resolving the device services so the code will no longer ignore
devices that got its services resolved after Paired signal.

New subject: [PATCH v4 4/5] doc/handsfree-audio-api: Add Acquire method
From: Luiz Augusto von Dentz <luiz.von.dentz(a)intel.com>
This adds Acquire method which can be used by agents that require
pulling the fd directly instead of waiting a NewConnection.
Note: sounds servers like PulseAudio do auto suspend streams when idle
for a certain amount of time and once anything happens it will resume
the stream, though this all happens in the so called IO thread in a
blocking fashion making it impossible to receive the fd via NewConnetion
causing the stream to fail to resume. There are other forms to work
around but this seems to be most convenient as we do want the auto
suspend feature to work properly but letting the stream to fail to
resume may create unexpected artifacts while the NewConnection is
handled in main thread.
