Modified Files:
        src/bin/sh: trap.c

Log Message:
Don't hard ignore signals that were ignored by our environment, because
when we try to set a trap on them it will not work. Also while I am here:
1. don't change the action status if the signal system call failed.
2. don't try to sigignore it if signal failed.
3. clear the signal mask in case our parent blocked it for us.
