Suren Baghdasaryan 36baf44179 lmkd: Restrict lmkd unsolicited notifications only to subscribed recipients 
lmkd unsolicited notifications can cause lmkd to block if clients are not
consuming them. Fix that by sending notifications to only subscribed
clients. Introduce LMK_SUBSCRIBE command to allow lmkd clients to subscribe
to event notifications. The only asynchronous event currently supported is
LMK_ASYNC_EVENT_KILL.

fail when we run command such as ./lmkd_unit_test
under the device shell.
