error.c (rb_bug_for_fatal_signal): renamed from rb_bug_context

Browse source 
Just refactoring.

The name "rb_bug_context" is completely unclear for me.
(Can you see that "context" means "machine register context"?)
The context is available only when a fatal signal (sigbus, sigsegv, or
sigill) is received; in fact, the function is used only for fatal
signals.  So, I think the name should be changed.
