This additionally turns on dom.ipc.processHangMonitor on non-m-c consumers of gecko, as well as turning off dom.ipc.reportProcessHangs on debug geckoview.

aForceRepaint wasn't doing what it claimed to do at all, as we've recently
learned. In current mozilla-central:
* All those arguments ended up in a RecvRenderLayers with aForceRepaint = true
(so far so good, that's expected).
* But it was ignored (so that aForceRepaint is always true to calls to
MakeVisible) from UpdateVisibility:
https://searchfox.org/mozilla-central/rev/f43ae7e1c43a4a940b658381157a6ea6c5a185c1/dom/ipc/BrowserChild.cpp#2523
* Plus that argument only does anything useful on current central if we get to
the end of MakeVisible(true). And MakeVisible() early returns if already
visible.
So all in all this seems somewhat useless, and nobody has complained about such
a thing in a long time.
It seemed to do what it promised when it was introduced in
https://hg.mozilla.org/mozilla-central/rev/27f6f789b194, but it seems the
refactoring in https://hg.mozilla.org/mozilla-central/rev/4df5fa6fa785 broke it.
I think the new setup is somewhat easier to reason about, and nobody seems to be
missing that.
I'll try to remove the forceRepaint() call itself on a follow-up.

So that paint doesn't reenter on layout, or mess with incomplete frame trees, or
what not.
I just early-returned rather than only skipping the PaintWhileInterruptingJS
call because I don't think we should be running untrusted scripts in the first
place when IsSafeToRunScript() is false.

This patch just adds a check to ensure that the BrowserChild from our window
is non-null. The other changes are just reordering some lines and removing a

This patch makes several changes to the kinds of URLs where we can cancel
content JS when navigating between them:
1) When navigating directly to a URL (e.g. by typing something into the
location bar and hitting Enter), we allow canceling content JS if the URLs
differ in any way *except* their ref ("#"). To help with this, we also
attempt to fix up the URL (e.g. by prepending "http://" to it).
2) When navigating through history, we allow canceling content JS if the
`prePath` part of the URLs differ. Most notably, this allows canceling
content JS when one of the URLs is an `about:` page (e.g. when hitting the
Home button).
3) We explicitly disallow cancelling content JS if the currently-running JS
is trusted or if the page being navigated away from is anything but
http(s): or file:.
4) We also disallow cancelling content JS for windows that are still being
created (e.g. when creating a new tab or window via `window.open`). For
more background on this, see the comments about `mCreatingWindow` in
dom/ipc/BrowserParent.h.
5) We ensure that, when attempting to cancel JS, the tab ID of the
currently-running script matches the original tab that requested the
cancellation. This avoids a race condition in which a particular JSContext
has already moved on to executing another tab's JS by the time we hit our
interrupt callback.

This patch fixes a race condition where we could request that a content page's
JS be cancelled during navigation in `HangMonitorChild::InterruptCallback`,
but the new page has already started loading by the time the JS is cancelled in
`XPCJSContext::InterruptCallback`, thus cancelling the JS of the new page. To
fix this, we now handle everything in `HangMonitorChild::InterruptCallback`,
making sure to only do anything for *content* scripts (to avoid inadvertently
cancelling the browser's JS).

In this part, we pass along the navigation type (and index for when using the
dropdown on the back/forward buttons). This allows us to check if there's a
top-level load "between" the start and end pages.
The patch might look a bit strange, since we're passing the navigation
operation to two places from RemoteWebNavigation.js (the normal message passing
that existed before this patch and the HangMonitor channel in this patch). This
is primarily to make it easier to stop passing the navigation info along the
HangMonitor channel once session history is uplifted into the parent process.
At that point, the check for whether there's a top-level load could happen in
TabParent (I think).

This patch passes a message through the HangMonitor channel when navigating
through history to cancel content JS that could hang the chrome JS in the
content process responsible for history navigation. If the content JS is
actually canceled, this also disables the BF cache for the current page, since
it could end up in an inconsistent state due to the JS cancellation.

Similarly to nsITabParent, TabChild is exposed to frontend code via nsITabChild. It's not clear what the future of this interface will be, but for now we can just rename it to nsIBrowserChild.

nsITabParent is exposed to frontend code and is generally used as a representation of a remote tab. We could just rename the interface to nsIBrowserParent and worry about it later, but I think it's better to rename the interface to nsIRemoteTab so that we can later work on splitting the interface away from the PBrowser protocol.
Note: Some frontend code refers to a TabParentId. This commit renames this to RemoteTabId. We need to figure out the purpose of TabId with fission.

This reverts the changes in bug 1360308, bug 1390143 and bug 1469603. Minidump
generation will now only happen on the main process' main thread which might
lead to hangs but is known to be fairly robust. Asynchronous generation proved
too brittle and enormously increased the complexity of this already
hard-to-read code.

Fairly straightforward. This should allow us to enable our

just piggybacking on the existing content process BHR.

This is fairly straightforward, other than the fact that the
nomenclature gets a bit awkward with the aForce parameter on
the ForcePaint methods. I'm not sure which direction to go with
this - "aForce" seems a fairly intuitive name for what we want,
and I'm kind of inclined to say the existing ForcePaint mechanic
should be renamed to something like PaintWithInterrupt, or
PaintWithPriority.

This patch goes through and changes a bunch of places in our tree which mention
this bug to use the new feature, making the methods more strongly typed.
There are probably more places in tree which could be changed, but I didn't try
to find them.
