I think this is about as far as the cleanup of this file will go at the moment. More can be done when data structure fields become safe, but then cleaning up the code here should follow naturally from those changes.

is that &mut something that c2rust inserts? it's not really needed and also unsound when that pointer is dangling (a dangling pointer would be sound if the slice length were 0). Not a problem in practice here but in general it seems odd to me.

Somewhat (it also looks extra weird since we didn't delete it as we partially cleaned it up/bitdepth deduplicated it). c2rust transpile sometimes has redundant &mut *s, and it also generates that kind of code when it really should generate addr_of_mut! to be sound (see immunant/c2rust#301).
builds on #733
