Re: [libvirt PATCH 6/6] ci: Enable address and undefined behavior sanitizers

meson supports the following sanitizers: "address" (e.g. out-of-bounds memory access, use-after-free, etc.), "thread" (data races), "undefined" (e.g. signed integer overflow), and "memory" (use of uninitialized memory). Note that not all sanitizers are supported by all compilers, and that more sanitizers exist. Not all sanitizers can be enabled at the same time, but "address" and "undefined" can. Both thread and memory sanitizers require an instrumented build of all dependencies, including libc. gcc and clang use different implementations of these sanitizers and have proven to find different issues. Create CI jobs for both.
