Joshua Peraza 59cdfbb031 linux: support multi client sockets in ExceptionHandlerServer
Multi client socket connections allow multiple clients to request crash
dumps from a handler process using a single, shared socket connection.

This connection mode does not support using a broker process which
requires a dedicated socket connection to ensure handler messages
aren't intercepted by the wrong clients.

The handler uses SIGCONT to indicate to the crasher when a crash dump
is complete (or has failed) and may continue.
