Delete some deprecated declarations (tailscale#18)

These are not referenced anywhere whether in our own source code
or in any publicly available source code.

The other deprecated declarations will also be deleted once
known usages have been cleaned up.

The hujson package has no compatibility guarantees,
so deletion is permissible.
