Summary

Ref T9640. In libphutil, switches to the PHP 7.1 async_signals mechanism when it is available.

Test Plan

With the next change, ran daemons with bin/phd start and bin/phd debug, then ^C'd them.

  • Before patch: long hang.
  • After patch: They responded to the signals normally and exited promptly.
