binder: Refactor: move FdTrigger to its own file / class.
Also move interruptable*Fully functions to RpcTransport so that we no
longer need pending() and pollSocket().
This also allows us to hide send() / recv(); callers should use
interruptableWriteFully / interruptableReadFully instead, because
those repsect the shutdown trigger.
- Fix one place to use interruptableWriteFully() instead of send() when
sending header.
interruptable*Fully are marked as virtual functions because TLS will
need to poll with events dynamically adjusted. See follow-up CLs for
TLS implementation.
