Message:

Rename setjmp/longjmp to context_save/context_restore

Once upon a time, I renamed context_save/context_restore to
setjmp/longjmp with the reasoning that they are almost
the same as setjmp/longjmp. I never got rid of the "almost",
so it ended up being somewhat confusing.
This is just a late correction of the old change.
