[RFC next v5 00/11] bluetooth: BlueZ 5 development patches

[mikel.astiz.oss@xxxxxxxxx (Mikel Astiz)]

From: Mikel Astiz <mikel.astiz@xxxxxxxxxxxx>

Sending v5 with the following changes:
- Leaked D-Bus matches removed as pointed out by Jo?o Paulo.
- Several warning messages added as suggested by Tanu.
- Minor code refactoring in pa_bluetooth_transport_release().

Again, the last 5 patches are sent for completeness despite the general consensus not to merge them.

The patchset is very similar to v4 as you can see in the following diff:
