More Assertions

[gheskett]

This is about as close as we're gonna get to test cases. Also good for helping out inexperienced hackers to diagnose crashes in common cases such as bad warp nodes.

There should be three types of assertions used:

• Static assertions (i.e. compile time)
• Debug assertions (run only if using debug features)
• Release assertions (run always).

Pinning this issue because this is an effort that should be considered by everybody starting immediately. There's no hard completion case here, but more assertions should in theory mean a more stable repo.

Most runtime assertions should only be active with non-release builds. There may be some situations where they should run in all cases, but this can come with a performance downside if they're placed in the wrong spots.
