upstream: Replace all calls to signal(2) with a wrapper around
sigaction(2). This wrapper blocks all other signals during the handler preventing races between handlers, and sets SA_RESTART which should reduce the potential for short read/write operations. OpenBSD-Commit-ID: 5e047663fd77a40d7b07bdabe68529df51fd2519
