	gdb/testsuite/gdb.base: corefile.exp 
Added files:
	gdb/testsuite/gdb.base: exitsignal.exp normal.c segv.c 

Log message:
	This patch  adds a new convenience variable called "$_exitsignal", which
	will hold the signal number when the inferior terminates due to the
	uncaught signal.
	
	I've made modifications on infrun.c:handle_inferior_event such that
	$_exitcode gets cleared when the inferior signalled, and vice-versa.
	This assumption was made because the variables are mutually
	exclusive, i.e., when the inferior terminates because of an uncaught
	signal it is not possible for it to return.  I have also made modifications
	such that when a corefile is loaded, $_exitsignal gets set to the uncaught
	signal that "killed" the inferior, and $_exitcode is cleared.
	
	The patch also adds a NEWS entry, documentation bits, and a testcase.  The
	documentation entry explains how to use $_exitsignal and $_exitcode in a
	GDB script, by making use of the new $_isvoid convenience function.
