2018-10-04src: name EmbededderGraph edges and use class names for nodesJoyee Cheung
This patch: - Refactors the `MemoryRetainer` API so that the impementer no longer calls `TrackThis()` that sets the size of node on the top of the stack, which may be hard to understand. Instead now they implements `SelfSize()` to provide their self sizes. Also documents the API in the header. - Refactors `MemoryTracker` so it calls `MemoryInfoName()` and `SelfSize()` of `MemoryRetainer` to retrieve info about them, and separate `node_names` and `edge_names` so the edges can be properly named with reference names and the nodes can be named with class names. (Previously the nodes are named with reference names while the edges are all indexed and appear as array elements). - Adds `SET_MEMORY_INFO_NAME()`, `SET_SELF_SIZE()` and `SET_NO_MEMORY_INFO()` convenience macros - Fixes a few `MemoryInfo` calls in some `MemoryRetainers` to track their references properly. - Refactors the heapdump tests to check both node names and edge names, distinguishing between wrapped JS nodes (without prefixes) and embedder wrappers (prefixed with `Node / `).

2018-05-04src: refactor `BaseObject` internal field managementAnna Henningsen
- Instead of storing a pointer whose type refers to the specific subclass of `BaseObject`, just store a `BaseObject*` directly. This means in particular that one can cast to classes along the way of the inheritance chain without issues, and that `BaseObject*` no longer needs to be the first superclass in the case of multiple inheritance. In particular, this renders hack-y solutions to this problem (like ddc19be6de1ba263d9c175b2760696e7b9918b25) obsolete and addresses a `TODO` comment of mine. - Move wrapping/unwrapping methods to the `BaseObject` class. We use these almost exclusively for `BaseObject`s, and I hope that this gives a better idea of how (and for what) these are used in our code. - Perform initialization/deinitialization of the internal field in the `BaseObject*` constructor/destructor. This makes the code a bit more obviously correct, avoids explicit calls for this in subclass constructors, and in particular allows us to avoid crash situations when we previously called `ClearWrap()` during GC. This also means that we enforce that the object passed to the `BaseObject` constructor needs to have an internal field. This is the only reason for the test change. - Change the signature of `MakeWeak()` to not require a pointer argument. Previously, this would always have been the same as `this`, and no other value made sense. Also, the parameter was something that I personally found somewhat confusing when becoming familiar with Node’s code. - Add a `TODO` comment that motivates switching to real inheritance for the JS types we expose from the native side. This patch brings us a lot closer to being able to do that. - Some less significant drive-by cleanup. Since we *effectively* already store the `BaseObject*` pointer anyway since ddc19be6de1ba263d9c175b2760696e7b9918b25, I do not think that this is going to have any impact on diagnostic tooling.
