[PATCH 14/14] bsd-user/signal: Create a dummy signal queueing function

[Warner Losh]

Create dummy signal queueing function so we can start to integrate other
architectures (at the cost of signals remaining broken) to tame the
dependency graph a bit and to bring in signals in a more controlled
fashion.
