Create a wrapper module called module-bluetooth-discover to avoid
breaking backward-compatibility of default.pa. This wrapper may
eventually be dropped altoghether with BlueZ 4 support.
For quite some time now the device driver module doesn't work well
without the discovery module, so for the BlueZ 5 support we'll prevent
the device driver module to be loaded if the discovery module is not
loaded.
Create the thread function, the render and push functions for A2DP, the
process message function for communication between the I/O thread and
the main thread, and other helper functions related to them.
Get the remote device information stored in pa_bluetooth_discovery. This
also creates the mandatory parameter 'path' for module-bluez5-device,
which is used to inform the object path of the remote device in BlueZ on
the module load.
bluetoothd always send the GetManagedObjects() reply messages with the
objects array argument following an in-depth order starting from the
root. That means parents will always be known at the time their children
objects are parsed, if clients parse the objects in the same order they
appear in the array, as we do in PulseAudio.
This commit tries to protect PulseAudio in the case bluetoothd changes
that behavior for some reason. It hasn't been tested, since this
situation never occurs.
Create the pa_bluetooth_transport structure to store information about
the bluetooth transport and utility functions to manipulate this
structure. The acquire() and release() operations are function pointers
in the pa_bluetooth_transport structure to make possible for different
transport backends to provide different implementations of these
operations. Thre is also a userdata field for the transport backend
provide data for the acquire/release functions.
This commit also creates a new function
pa_bluetooth_device_any_transport_connected() to check if there is any
audio connection between the host and a remote device.
pa_bluetooth_discovery is the struct that holds information about known
Bluetooth audio devices and other information about the Bluetooth stack.
This commit also creates bluez5-util.[ch], which will hold a lot of
utility functions to help with the BlueZ 5 support.
module-bluetooth-proximity has not worked for quite a while, since it
uses pre-BlueZ4 APIs. Nobody complained since then, which is a good
indication that it doesn't have much users. Even the original commit
message refers to it more as a toy than as something of great use: "add
new fun module that automatically mutes your audio devices when you
leave with your bluetooth phone, and unmutes when you come back"
Removing it we completely remove the dependency on libbluetooth.
