After enable Fission, we're not able to resume media in the different process, because the current way we use can only notify one process and would cause the media on other process can't be resumed.
Therefore, we should use the browsing context to notify the web content which might be on different processes.

Currently when we have an in-process WindowProxy object, we will attempt
to either use the cached mWindowProxy value, or fetch the
nsGlobalWindowOuter object from through the nsDocShell. Unfortunately,
when the BrowsingContext is detached, we will fail to get the
nsGlobalWindowOuter object. This happens to be OK for our test cases, as
the cached mWindowProxy value doesn't have the chance to go away, but
isn't acceptable long-term.
These patches exascerbated that issue by causing the nsDocShell pointer
itself to be cleared when it is destroyed, which caused the Remote
WindowProxy logic to be triggered. To deal with that case, this patch
adds a new mIsInProcess flag to continue to act like the old code-path.
In the future, we will need to also handle ensuring that the
nsGlobalWindowOuter lives for long enough, however that is not being
done in this patch in order to land it sooner rather than later.

This is important to allow creating BrowsingContexts outside of the process
where they are going to be used. This is largely a re-arrangement of existing
code.
There is currently no way to do this type of attaching for browsing contexts in
existing BrowsingContextGroups, which creates some limitations, but happens to
be sufficient for us in the current situation.

Add the origin ContentParent to a CanonicalBrowsingContext's group
when a CanonicalBrowsingContext is created from IPC. With this it is
possible to keep track of all child processes associated with a
BrowsingContextGroup.

This implements the step of choosing a browsing context with
FindWithName, which should be equivalent to calling
nsIDocShellTreeItem.findItemWithName passing null for 'aRequestor' and
'aOriginalRequestor' and false for 'aSkipTabGroup'.

This patch changes the logic such that we use the new direct
BrowsingContext ParamTraits implementation when possible, and avoids
doing manual lookups.

This patch takes the approach of taking a reference, so that we can land
it into the tree more quickly & fix issues we have.
This isn't a final solution by any means, we should also do something
along the lines of the StableState approach, but it should be sufficient
for now.

As the user gesture activation flag is a flag which is used to reflect whether the corresponding document of browsing context has been activated by user or not, we should reset the flag when the top level window changes its document.

Everytime we set the flag on top level BrowsingContext, it would automatically be sync to its corresponding ChromeBrowsingContext.

This patch moves the user gesture activation flag from saving in document to saving in browsing context. The flag would be saved in the top level browsing context and then every time we need to check for that flag, we will request it from top level browsing context.

Add top-level and auxiliary browsing contexts to a group of
BrowsingContexts on creation and store a pointer to that group in all
children of the BrowsingContexts in the group. With this it is
possible to compute the transitive closure of related browsing
contexts.
Since we'll not be using linked lists of BrowsingContexts for neither
groups nor children we can move children to be an array of
BrowsingContexts and adjust to use a the more convenient HashMap for
roots.

This allows getting the set of all window globals for a given browsing context.
This is less useful at the moment as the active window global is not exposed as
such. That will be added as a follow-up.

By replacing nsWebBrowser's implementation of the
nsIBaseWindow.initWindow and nsIBaseWindow.create with a new static
nsWebBrowser::Create method we make it possible to pass arguments
directly when creating an nsWebBrowser, for example the opener
BrowsingContext. As a bonus we can do away with
nsWebBrowser::mInitInfo!

from BrowsingContext there. After that make sure that all
BrowsingContexts created in the parent process is actually
ChromeBrowsingContexts and all BrowsingContexts in the child processes
are BrowsingContexts.
