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.
