V5:
Fixes according to Johan comments
V4:
Added device name caching in device list
Changes according to Johan comments
V3:
Removed adapter bonding state
Added device list in order to track bonding state per device.
Fix for incoming legacy paring. We act here same as Bluedroid.
V2:
Bonding state added.
V1:
With those patches it is possible to bond from remote device and in addition
you will see the name of remote device on Android pairing request pop up.
Lukasz Rymanowski (4):
android: Update bond state on incoming bonding
android: Cache device name on device list.
android: Update bond state on auth and connect failed
android: Change TODO with explaining comment

All patches have been applied. Thanks.
I did need to do some (minor) coding style tweaks for 2/4 though.

1.8.4
Before sending any ssp request or pin code request up to HAL library we
need to send bond state change with bonding state. Otherwise incoming
bonding is not correctly handled by Bluetooth.apk.
In this patch also device list has been added in order to e.g track
bonding state.
Note: For incoming paring (security mode 3) there is a need to send
HAL_EVE_REMOTE_DEVICE_PROPS before HAL_EV_PIN_REQUEST.
It is because Android will crash due to bug in pinRequestCallback
function in java. Android checks if device is already in HashMap and if
not then creates device, but forget to use that one, but instead do
operations on NULL. By sending HAL_BOND_STATE_BONDING event it works
better but we have race issue. It is because new device is added to
HashMap not in callback context but later after BONDING msg will be
received by BondStateMachine. If it happens before pin_request_cb hits
java then we are fine, otherwise not. So for that reason we send
HAL_EV_REMOTE_DEVICE_PROPS so in the java handler class new device will
be added to HashMap in the callback context.
In ssp case we don't have this problem as we send device found once acl
is created.
