We were keeping nsDocShell::mHistoryId and nsDocShell::mOSHE as keys. They weren't quite good because: 1. While loading an iframe, they were being registered twice with the same ids(for about:blank and the real URL) sometimes. 2. It wasn't possible to access to the parent mHistoryId and mOSHE from a child processes if the parent is in a different process. That may not be the case for now, but it will be after fission. So we had to find other IDs to: 1. Determine the Tab of the frames. 2. Determine the URLs of the frames. For the first use case, we were using nsDocShell::mHistoryId for that purpose but that was wrong. The closest thing that we can get to a tab ID is BrowsingContext ID because they don't change after a navigation. But iframes have different BrowsingContext's, so we still need to create a tree to construct a tab content. That can be either in the front-end or capture time. For the second use case, we were using a key pair of mHistoryId and mOSHE. We now chose to keep inner window IDs for that purpose. Inner window IDs are unique for each navigation loads because inner window correspond to each JS window global objects. That's why we can use that without any problem. But one problem is that we cannot handle `history.pushState` and `history.replaceState` changes with that change since window global objects won't change during those. But that was the best thing we can do after fission. So this will be a small sacrifice for us to keep that functionality working after fission. In that patch we also remove the registration/unregistration calls. We are going to add those calls in the next patch.
