Provide sigaction() for Windows.
Commit 9abb2bfc left behind code to block signals inside signal
handlers on Windows, because our signal porting layer didn't have
sigaction(). Provide a minimal implementation that is capable of
blocking signals, to get rid of platform differences. See also related
commit c94ae9d8.
