rust_binder: report netlink transactions

Browse source

The Android Binder driver supports a netlink API that reports
transaction *failures* to a userspace daemon. This allows devices to
monitor processes with many failed transactions so that it can e.g. kill
misbehaving apps.

One very important thing that this monitors is when many oneway messages
are sent to a frozen process, so there is special handling to ensure
this scenario is surfaced over netlink.
