Once again, rework the signal handling to be even more correct. We no
longer segfault when running test/signal/sigchld.c, which exposed a bit of a rats nest. The problem ended up being a erroneous syscall defination, but in the process of finding that out, I scrubbed things up nicely and adapted things to use the rt_ signals if they are available. This now passes all the signal tests. -Erik
