Delegates the Immediate Alert Level control to the caller(client).
Immediate Alert Service is shared between Path Loss and Find Me.
Three signal level states are defined: "good", "regular" and "weak".
Meaning that at least two thresholds are necessary to implement a
proper state transition. "unknown" will be returned if the link is not
active. For Path Loss, the logic to trigger the writting operation of
the Immediate Alert Level characteristic needs to be implemented in
the client. SignalLevel can be only one of the inputs to define when
and which value to write in the characteristic.
Currently, use of RequestSession and SetProperty adapter method
calls sets global_mode to on. Switching adapter off via plug-in
interface in this scenario releases all sessions, that, in turn,
restores adapter's state to global_mode, which is on.
Result is the adapter is switched off and immediately switched on.
This patch fixes such inconsistency by overwriting global_mode to
mode off when request comes from plug-in.
Without this patch, when dropping RFCOMM channel to sap server, the
component's channel cleanup process doesn't release assigned GIOChannel
resources since conn->io is set to NULL before calling sap_conn_remove
(which would normally do the g_io_channel_unref).
As these files are auto-generated they need to be marked as BUILT_SOURCES
so that we don't run into a build race later on. lib/bluetooth is removed
by clean-local so this doesn't need to be in CLEAN_FILES
Local initiated disconnection will be triggered when the last GAttrib
reference is dropped. For remote initiated disconnection it is necessary
to track the socket HUP registering disconnection GAttrib callback.
In the ATT callbacks registration function, the connection callback should
not be called in the same main loop iteraction to avoid accessing not
initialized data in the profiles during probing.
Connection should not be dropped if there is at least one ATT connection
callback registered. After discovering primary services over the LE link,
GAttrib ref needs to be held to allow notifying an active connection
while registering connection callbacks(inside plugins probing).
In the Generic Attribute API, when DiscoverCharacteristics is called
ATT connection should be requested if the link is not up. A query
list is required to control when the link can be disconnected since
the discover finishes after receiving all caracteristic declarations.
In the Generic Attribute API, the ATT connection should be requested
on demand. In the case of watchers, the connection doesn't need to be
stay up if there isn't watcher registered.
Generic attribute API should not actively manage L2CAP connections.
GAttrib instance is notified through registered callbacks. SetProperty
or DiscoverCharacteristic now returns NotConnected error if the link
is down.
Get rid of local structure to store all GATT primary services of a
given device. "primary" struct has been renamed to "gatt_service"
to avoid misinterpretation or confusion with "att_primary".
This sometimes cause bluetoothd to burn cpu when an adapter is removed
from the system.
Since the watch is not really bond to any adapter, in fact it is added on
plugin .init, its removal is now moved to plugin .exit.

If the device is disconnected and the first ATT connection callback is
registered, the first connection attempt can be triggered instead of
waiting the timer.
This initial approach uses a hardcoded timer(45s). Passive scanning
or any other mechanism to avoid unnecessary connection attempt is not
supported at the moment. For LE, device discovery needs to be executed
to update the kernel advertising cache to allow re-connections.
Function intends to be used by profiles to inform that a connection
is required and the callback that needs to be called when the it is
established. New header is required to avoid non GATT based profiles
including GAttrib header.
