This patch makes the MallocSizeOf stuff in Stylo work more like the HeapSizeOf stuff already in Servo, except better. In particular, it adds deriving support for MallocSizeOf, which will make it easier to improve coverage. The patch does the following. - Combines servo/components/style/stylesheets/memory.rs and the heapsize crate into a new crate, malloc_size_of. - Forks the heapsize_derive crate, calling it malloc_size_of, so that MallocSizeOf can be derived. - Both the new crates have MIT/Apache licenses, like heapsize, in case they are incorporated into heapsize in the future. - Renames the methods within MallocSizeOf and the related traits so they are more concise. - Removes MallocSizeOfWithGuard. - Adds `derive(MallocSizeOf)` to a lot of types, in some cases replacing an equivalent or almost-equivalent hand-written implementation. - Adds stuff so that Rc/Arc can be handled properly.
