[OE-core] should all class files be inherited by *something*?

I believe it's for supporting the scons build system. scons isn't hugely 
popular though so I guess it's not surprising that nothing in OE-Core uses it.

I think oelint.bbclass is a really out-of-date recipe lint checking tool. I 
wonder if anyone has used it lately. There could be value in bringing it up-
to-date though.

It's worth noting that we may have a number of classes that are supposed to be 
generally useful in OE-Core that aren't used within OE-Core itself. This is a 
good idea because it reduces the proliferation of different versions of such 
classes in multiple layers.

Cheers,
Paul
