	Now containers run with "docker run -it" support control characters like ^C and ^Z. This required refactoring our signal handling a bit. Signals delivered to the "runsc boot" process are turned into loader.Signal calls with the appropriate delivery mode. Previously they were always sent directly to PID 1.

2018-09-07	Continue handling signals after disabling forwarding	Michael Pratt
	Before destroying the Kernel, we disable signal forwarding, relinquishing control to the Go runtime. External signals that arrive after disabling forwarding but before the sandbox exits thus may use runtime.raise (i.e., tkill(2)) and violate the syscall filters. Adjust forwardSignals to handle signals received after disabling forwarding the same way they are handled before starting forwarding. i.e., by implementing the standard Go runtime behavior using tgkill(2) instead of tkill(2). This also makes the stop callback block until forwarding actually stops. This isn't required to avoid tkill(2) but is a saner interface.

2018-08-27	Add command-line parameter to trigger panic on signal	Fabricio Voznika
	This is to troubleshoot problems with a hung process that is not responding to 'runsc debug --stack' command. PiperOrigin-RevId: 210483513 Change-Id: I4377b210b4e51bc8a281ad34fd94f3df13d9187d

	We have been unnecessarily creating too many savable types implicitly. PiperOrigin-RevId: 206334201 Change-Id: Idc5a3a14bfb7ee125c4f2bb2b1c53164e46f29a8
2018-06-21	Drop return from SendExternalSignal	Michael Pratt
	SendExternalSignal is no longer called before CreateProcess, so it can enforce this simplified precondition. StartForwarding, and after Kernel.Start. PiperOrigin-RevId: 201591170 Change-Id: Ib7022ef7895612d7d82a00942ab59fa433c4d6e9
2018-06-21	Forward SIGUSR2 to the sandbox too	Fabricio Voznika
	SIGUSR2 was being masked out to be used as a way to dump sentry stacks. This could cause compatibility problems in cases anyone uses SIGUSR2 to communicate with the container init process. PiperOrigin-RevId: 201575374 Change-Id: I312246e828f38ad059139bb45b8addc2ed055d74
