[Karmic] Bluetooth input fixes

[Brian Rogers]

For Karmic's kernel, I recommend the following cherry-picks from upstream:

364f63519d94442ed373ac7da79033c8282df46a
9eba32b86d17ef87131fa0bce43c614904ab5781
edad63886993d18ab800c49f6587a93432ef8b35

They ensure Bluetooth input devices such as keyboards and mice are 
removed completely and in proper order when they disconnect, so that HAL 
sees the removal and relays the info to X. Without this, disconnected 
Bluetooth devices are left in X, and duplicates appear on each 
reconnection until the input device limit is hit. Then no newly 
connected input devices will work.
