[Qemu-devel] [PATCH for-1.5 7/9] build: disable QOM cast debugging for official releases

[Paolo Bonzini <pbonzini@redhat.com>]

QOM cast debugging is useful, but it can have a substantial cost.  We
will add a configure option to toggle it, in the meanwhile let's keep
it disabled in official releases (including -rc).

Replace the old CONFIG_ZERO_MALLOC that had the same rules but has
been unused since we switched to g_malloc/g_free.
