Add SIGSTOP and SIGTSTP handling to issig

Browse Source 
This change adds SIGSTOP and SIGTSTP handling to the issig function; 
this mirrors its behavior on Solaris. This way, long running kernel 
tasks can be stopped with the appropriate signals. Note that doing 
so with ctrl-z on the command line doesn't return control of the tty 
to the shell, because tty handling is done separately from stopping 
the process. That can be future work, if people feel that it is a 
necessary addition.
