This is largely a search and replace. There's probably some IWYU errors (files
that don't include memory when they should and those that do when they
shouldn't), but fixing those is out-of-scope for this conversion work.

I am not the right reviewer for this; I am not familiar with most of this code
so won't know if something subtle is wrong.  You can try asvitkine@ or someone
else (or he may suggest someone else).
