This patch makes `nsDocShell::GetPresShell()` and
`nsDocShell::GetEldestPresShell()` return `mozilla::PresShell*` and
some non-public methods use `mozilla::PresShell*` directly.

Currently TabParent is refcounted, but nsFrameLoader hold a weak pointer. The pointer
should be cleared out when the TabParent is destroyed, but that's a bit of a footgun
and it's not obvious that we always do this correctly.
Because TabParent holds a reference to a nsFrameLoader and the frame element (which
contains a nsFrameLoader), I think this means we need to cycle collect TabParent.
`nsPresContext` should use `mozilla::PresShell` directly instead of
`nsIPresShell`. This patch makes it.
Unfortunately, `nsPresContext` and `nsIFrame` have `PresShell()`. Therefore,
we cannot use `PresShell*` in its methods so that this patch uses `mozilla::`
namespace prefix.
It might be better to rename them as `PresShellPtr()` in another bug.

This makes `Document::GetShell()` return `PresShell*` instead of `nsIPresShell`.
Additonally, "shell" is unclear ("docshell" vs. "presshell"). Therefore, this
also renames `Document::GetShell()` to `Document::GetPresShell()`.
Similarly, some other method names of `Document` are also renamed from
`*Shell*` to `*PresShell*`.

Adds a method for to nsFrameLoaderOwner destroying and rebuilding a
FrameLoader in order to facilitate a process switch. Method works
without requiring that the work be done in the frontend.

We have mRemoteFrameChild which owns a RemoteFrameChild, but
mRemoteFrame is just a state. Change to mIsRemoteFrame to reflect
this.

This was introduced in bug 726817 for B2G stuff and there is no call site of
SetClampScrollPosition now and the only one entry point to call the function
was nsIFrameLoader.clampScrollPosition which was removed in
https://hg.mozilla.org/mozilla-central/rev/cd9aace7bb96 .
ScrollFrameHelper::ShouldClampScrollPosition() had always returned true in both
cases of root and non-root scrollable frames. (In the case of non-root
scrollable, nsFrameLoader.mClampScrollPosition is initially set to true and
nobody changes the value)

This patch tries to move them to `ContentParent` instead.
`ProcessPriorityManagerImpl::ObserveContentParentCreated` could not be moved
due to using `do_QueryInterface` to cast from a `nsISupports` down to the
`ContentParent` object. This could be fixed to remove the interfaces entirely,
but I left that for a follow-up.

Remove the ability for fake plugins to create frames. Fake plugins
aren't used anymore, so we can simplify nsFrameLoader a bit by
removing some of the related checks.

This commit removes the dependency on RenderFrame from nsDisplayRemote so that
it can work in child processes with remote subframes. Instead nsDisplayRemote
now works with an nsFrameLoader, which will return the LayerId from either
the RenderFrame (for top-level remote browsers), or from RemoteFrameChild
(for remote subframes).

A TabParent for a remote subframe will have the same owner content as the top-level
remote browser. This means that 'TabParent::GetFrameLoader()' will return the
frame loader of the top-level remote browser.
This is fine for getting the layer manager and compositor for connecting layer trees,
but the frame loader is also used to acquire a TabParent for its process ID. This
is incorrect in the remote subframe case, and will lead to the compositor rejecting
layer transactions for the remote subframe because it will only accept them from
the top-level remote browser's process.
This commit switches RenderFrame to just hold on to TabParent, and acquire the
nsFrameLoader as necessary.
Another change is to RenderFrame::SetOwnerContent. Previously this method would
take the new owner content and check an assertion. I don't see much value in the
assertion, so I've removed it. Additionally, now that we acquire the owner content,
and therefore the layer manager, from TabParent, we need to ensure that
RenderFrame::SetOwnerContent is ran after the TabParent has had it's owner content
updated. So the callsite has been moved into TabParent. This resolved a test failure
with frame loader swapping.

This commit hooks up the pieces of the PRemoteFrame protocol that
will proxy initialization, sizing, and display messages. The messages
chosen are just enough to start the frame and get an initial rendering.

This commit hooks up nsFrameLoader in the child process to use the
PRemoteFrame protocol to support remote iframes. This is only activated
when a special pref is set, and the iframe has a marker attribute on it.
For example:
<iframe fission/>
In the future, we should unify nsFrameLoader to operate on a common
interface between the parent process top-level browser, and child
process subframe case. This commit just adds a new member that can
be used instead of mRemoteBrowser, when appropriate. IsRemoteFrame()
will return true for both cases.

Summary: Really sorry for the size of the patch. It's mostly automatic
s/nsIDocument/Document/ but I had to fix up in a bunch of places manually to
add the right namespacing and such.
Overall it's not a very interesting patch I think.
nsDocument.cpp turns into Document.cpp, nsIDocument.h into Document.h and
nsIDocumentInlines.h into DocumentInlines.h.
I also changed a bunch of nsCOMPtr usage to RefPtr, but not all of it.
While fixing up some of the bits I also removed some unneeded OwnerDoc() null
checks and such, but I didn't do anything riskier than that.
Make the WindowProxyHolder hold a strong reference to a BrowsingContext, as in the future
we might not have a nsPIDOMWindowOuter (if the document is loaded in a different process).
