From 27500d529f7fb87eef8812278fd1bbca67bcba72 Mon Sep 17 00:00:00 2001

Subject: New sync package.

* Rename syncutil to sync.
* Add aliases to sync types.
* Replace existing usage of standard library sync package.

This will make it easier to swap out synchronization primitives. For example,
this will allow us to use primitives from github.com/sasha-s/go-deadlock to
check for lock ordering violations.

Updates #1472
