add explicit 1-arg and 3-arg sig handler functions
Currently, whether the OS-level signal handler function is declared as
1-arg or 3-arg depends on the configuration. Add explicit versions of
these functions, principally so that POSIX.xs can call which version of
the handler it wants regardless of configuration: see next commit.
