healthd: notify listeners using local copy of list, drop lock
Binder currently may service an incoming oneway transaction whenever
an outbound oneway call is made (if there is already a pending
incoming oneway call waiting). The unexpected nested method call
blocks forever on a recursive mutex acquire because healthd is single-
threaded. The binder behavior is considered a bug and may change in
the future. For now, work around this in healthd.
Make a local copy of the listeners list, then drop the lock and
perform the outbound calls on the local copy of the list.
Bug: 38201220
Test: Marlin with modified client calling scheduleUpdate() repeatedly
