The previous method, using zassert.h and hoping nothing includes assert.h (which, on glibc at least, just does "#undef assert" and puts its own definition in...) was fragile - and actually broke undetected. Just provide our own assert.h and control overriding by putting it in a separate directory to add to the include path (or not.) Signed-off-by: David Lamparter <equinox@opensourcerouting.org>
