diff: Fix signal handling.

[Tyson Dowd]

Hi,

This should (hopefully) fix the problems with profiling under Linux.

===================================================================


Estimated hours taken: 0.5

Fix some problems with signal setting.

runtime/mercury_signal.c:
runtime/mercury_signal.h:
	- Use Code * instead of void * for the type of signal handlers.
	- Use sigaction if HAVE_SIGACTION is defined, not HAVE_SIGINFO_T.
	- Use SA_SIGINFO only if it is defined.
