This macro has some advantages over the standard library one: - It prints the place where the macro was triggered - It "references" the condition even in Release to avoid warnings - In release, if possible, it gives compiler hints It is basically is stripped down version of the ASSERT macros I wrote for the Daemon engine in src/common/Assert.h This commit also removes the stray "backend" namespaces for common/ code.
