showerror/showbug now ignore errors based on callsite, not error message

Also they can ignore up to 10 different errors instead of only the last one.

This is accomplished using wrapper functions written in C which pass the
function return address as an argument, something that can't be done in FB.

I implemented this so that errors like "illegal readblock call 5 0" can be
ignored; previously only identical messages could be matched
