Add (un)linkToDeath to generated interfaces.
(un)linkToDeath is now a part of IBase, and can be
called on any generated HIDL interface. The implementation
is a no-op, except in proxy objects, which are by
definition a different process than the interface they point
to.
Since clients are not aware of the transport implementation, we must
wrap the transport-independent callback in a transport-specific
callback object. In case of binder, that object is a
hidl_binder_death_recipient.
The binder proxy object contains a list of registered death
recipients, as well as a mutex to protect access to the list.
The list is required to allow us to map back transport-independent
callbacks to transport-dependent callbacks in unlinkToDeath().
