style: Detabify indentation of the C code maintained by the core.

This just detabifies to get rid of the mixed tab/space indentation.

Applying consistent indentation and dealing with other tabs are another issue.

Done with `expand -i`.

* vutil.* left alone, it's part of version.
* Left regen managed files alone for now.
