Spike: Can I unite to_* and stabilize_*?

[jonthegeek]

If I can make stabilize_* fast for defaults, I don't need multiple functions. In any case, I think I want everything to be named stabilize_. Maybe if I need more args I use stabilize__more?

The speed hit appears to be negligible, and it's actually considerably faster to check NULLs, which might prove useful. Fastest is with a single shared function that does NOT use S3. Might be possible to make it even faster by moving the S3 stuff inside the length check; putting the length check up front appears to be on of our biggest gains.
