add PERL_USE_3ARG_SIGHANDLER macro
There are a bunch of places in core that do
#if defined(HAS_SIGACTION) && defined(SA_SIGINFO)
to decide whether the C signal handler function should be declared with,
and called with, 1 arg or 3 args.
This commit just adds
#if defined(HAS_SIGACTION) && defined(SA_SIGINFO)
# define PERL_USE_3ARG_SIGHANDLER
#endif
Then uses the new macro in all other places rather than checking
HAS_SIGACTION and SA_SIGINFO. Thus there is no functional change; it just
makes the code more readable.
However, it turns out that all is not well with core's use of 1-arg
versus 3-arg, and the few commits will fix this.
