[PATCH 0/3] Introduce BUG_ON(cond, msg) MACRO

On reviewing [1] I wondered why there are so many asserts and wondered
if these asserts could have been prevented by a better functionality around
bug reporting in our code.

Introduce a BUG_ON macro, which is superior to assert() by
 * being always there, even when compiled with NDEBUG and
 * providind an additional human readable error message, like BUG()
 
Opinions?

Thanks,
Stefan
