Some platforms (eg: Trusty) are extremelly memory constrained, which doesn't necessarily work well with some of Scudo's current assumptions. `Vector` by default (and as such `String` and `ScopedString`) maps a page, which is a bit of a waste. This CL changes `Vector` to use a buffer local to the class first, then potentially map more memory if needed (`ScopedString` currently are all stack based so it would be stack data). We also want to allow a platform to prevent any dynamic resizing, so I added a `CanGrow` templated parameter that for now is always `true` but would be set to `false` on Trusty.
