This will allow users to specify signals by name.  Needed to make docker run --stop-signal
work as defined by systemd.

man systemd

defines the proper way to shutdown a systemd running as pid 1 in a container as

SIGRTMIN+4

0e50d946a2 Signal to stop a container. 
Allow to set the signal to stop a container in `docker run`:
- Use `--stop-signal` with docker-run to set the default signal the container will use to exit.

e787296c75 Ensure goroutines dump is not truncated 
Calling runtime.Stack requires the buffer to be big enough to fit the
goroutines dump. If it's not big enough the dump will be truncated and
the value returned will be the same size as the buffer.

The code was changed to handle this situation and try again with a
bigger buffer. Each time the dump doesn't fit in the buffer its size is
doubled.

95fcf76cc6 Add SIGUSR1 handler for dumping stack/goroutine traces 
Add handler for SIGUSR1 based on feedback regarding when to dump
goroutine stacks.  This will also dump goroutine stack traces on SIGQUIT
followed by a hard-exit from the daemon.
