Summary: The initial implementation used an ASan like Chunk class that was deriving from a Header class. Due to potential races, we ended up working with local copies of the Header and never using the parent class fields. ScudoChunk was never constructed but cast, and we were using `this` as the pointer needed for our computations. This was meh. So we refactored ScudoChunk to be now a series of static functions within the namespace `__scudo::Chunk` that take a "user" pointer as first parameter (former `this`). A compiled binary doesn't really change, but the code is more sensible. Clang tends to inline all those small function (in -O2), but GCC left a few not inlined, so we add the `INLINE` keyword to all. Since we don't have `ScudoChunk` pointers anymore, a few variables were renamed here and there to introduce a clearer distinction between a user pointer (usually `Ptr`) and a backend pointer (`BackendPtr`).
