Subject: [PATCH 0/2] Additional CondVar methods needed by Rust Binder

This patchset contains some CondVar methods that Rust Binder needs.

The CondVar type implements a condition variable, and tries to mirror
the API of the CondVar type provided by the Rust standard library [2].
It is implemented using a `wait_queue_head`.

Please see the Rust Binder RFC for usage examples [1].

Users of rust: sync: add `CondVar::notify_sync`:
	[PATCH RFC 04/20] rust_binder: add work lists
	[PATCH RFC 07/20] rust_binder: add epoll support
	[PATCH RFC 08/20] rust_binder: add non-oneway transactions

Users of rust: sync: add `CondVar::wait_timeout`:
	[PATCH RFC 15/20] rust_binder: add process freezing
