Add missing DHT_bootstrap to CMakeLists.txt.

- This PR also adds a DEBUG cmake option that enables -DTOX_DEBUG.
- We also remove `-Wall`, because there are too many warnings, and nobody really
  looks at them at the moment. We'll see about fixing them soon. We'll also want
  to enable `-Werror` at some point.
- Finally, this PR enables `-O3` to make sure toxcore still works correctly
  under heavy compiler optimisations.
