Generally we don't change the names of old functions that don't match the
current style guidelines (there's *a lot* of code that predates the style
guidelines, and this would cause a lot of churn).

Nevertheless, it'd be nice to have in-place variants.  I think something
like `SwapByteOrderInPlace()` or `ReplaceByteOrder()` might work with the
naming scheme in the file and minimize code churn.

Anyone else have an opinion on this?  Personally, I prefer Artyom's
proposal (renaming `SwapByteOrder`).
