Used sed to replace base::MakeUnique, and remove ptr_util.h includes.
Then grepped for base::WrapUnique and manually re-added necessary
ptr_util.h includes.

> <sync_files> | xargs sed -i 's/base::MakeUnique/std::make_unique/g'
> <sync_files> | xargs grep WrapUnique | cut -d":" -f1 | uniq
> <sync_files> | xargs sed -i 'd/#include "base\/memory\/ptr_util.h"'
