When sanitizing, delay making writable
...
Before, as soon as we needed to make an edit, we tried to make the blob
writable inplace. That grows code unnecessarily though. We can simply
fail, make writable, then start again. That's indeed what the fallback
was doing anyway.

Cleanup Extension lookups
...
Two things:
1. Allow nested Extension lookups. The offset is always positive, so
it can't loop circularly.
2. Move the check for all Extension subtables having the same lookup
type to the correct place. Before it wasn't really working.

Fail sanitize on major version mismatch
...
We handle major-version differences via get_for_data(), so sanitize
should never see a major version mismatch.
