Subject: [PATCH 0/4] Add support for new AVRCP ctrl interface

Android Lollipop has new interface for AVRCP controller. It has
one command and two callbacks. Patchset updates support for IPC doc,
hal-msg, HAL part and client part.

I was thinking in something like this:

Opcode 0x82 - Connection State Notification

Notification parameters: State (1 octet)
Remote Address (6 octets)
since: 5.0

Sure, I will add at bottom in both hal-ipc-txt and hal-msg.h.

So where should we keep changes related 5.0?

This should probably be added to the bottom as we did with other new
HAL. Btw, perhaps we should keep a history of API changes e.g. since:
5.0 per opcode so it become easier to identify changes in the future.

Since for the others interface added in 5.0 we did append to the end
this one should also go there, otherwise we will have to reorganize
all the ids.
