pa_bool_t and dbus_bool_t cannot be used interchangably since their size
might (and do) vary. This caused a crash on some systems which was
reported and root caused by: Aidan Thornton <makosoft@googlemail.com>.

Allow module-bluetooth-device to listens to HandsfreeGateway state
changes using DBUS signals. When an handsfree connects, module-bluetooth-device
is loaded and goes to playing state. When the handsfree disconnect audio,
the card profile is set to "off". If the headset connects audio again after
that, the card profile should switch to "hfgw" again to match state of audio
connection.
This patch will add the necessary quirks so that pulseaudio can register
an endpoint on the /MediaEndpoint/HFPHS path. This endpoint is to be
used for HFP Handsfree profile.
We used to support older DBus versions but 1.3.0 is two years old
now and by requiring it we cut down of deviated code paths at
runtime and thus have less support issues.

This pulls a2dp-codecs.h from BlueZ which contains the capabilities
structures for SBC and MPEG. We currently have these manually added to
ipc.h, so pulling this header makes our files identical to upstream.
It's perfectly normal for BlueZ to disable some endpoint types, so printing a
log message at error level isn't a good idea.
For facilitating an informative message in case some endpoint type is disabled,
the send_and_add_to_pending() function interface is also changed to be more
generic (the pa_bluetooth_device pointer is replaced with a void pointer).
NREC stands for Noise Reduction and Echo Cancelation, it can be changed
at any point by the headset.
When set to "1" indicates that those algorithms shall be enabled by
default and "0" means the headset probably have them active so they
should be disabled in PA side.
Acquire now return input and output MTU of the file descriptor so it is
no longer necessary to get those after acquiring the fd, which less round
trips and faster response time when switching profiles.
Create the 'Handsfree Gateway' profile for bluetooth cards and add
filters for 'org.bluez.HandsfreeGateway' to the discover module so
module-bluetooth-device is loaded with the correct profile when a
Handsfree Gateway connects to bluetoothd (in this case bluetoothd
is acting as the headset).
When an GetProperties() reply arrives after we already deleted the
device structure for it make sure we don't accidentaly touch the
invalidated object.
