Crash annotations in content processes are currently sent over IPC via
shared memory buffers. To pave the way for the Rust rewrite of the exception
handler we are removing this code and gathering all the crash annotations
within the content processes themselves. This patch causes annotations to be
stored in the global table of each content process. They are then streamed
out to the parent process by the exception handler together with the
exception-time annotations.
This has a number of benefits:
* we have one less channel to exchange data between content processes and
the parent process
* we save memory because we don't need to allocate the shared memory buffers
* annotations are faster because we don't stream them all out every time one
changes
* we won't truncate annotations anymore if we run out of space in the shared
segment.
* we don't need delayed annotations anymore, so we can get rid of the
associated machinery
As I refactored the code I tried to adjust all the obsolete comments,
consolidate shared code and remove the redundant steps that were sometimes
present. In many places we had two entire crash annotation tables we merged to
change just a couple; that comes from the fact that historically we loaded
them from disk. Now it doesn't matter anymore and we can just go ahead and
change the ones we care about.

TabGroup never really made any difference in which thread something go
dispatched to. This was the intended use, but development of TabGroups
with abstract main threads never made it that far. The good thing is
that thish makes it safe to also remove to the SystemGroup and instead
switch all SystemGroup dispatches to dispatches to main thread.
Timers for setTimeout and workers were the sole users of wrapped and
throttled event targets, that those throttled queues have been moved
to the BrowsingContextGroup and are now accessed explicitly.
The SchedulerEventTarget has been removed, since there are no longer a
separate event target for every TaskCategory. Instead a
LabellingEventTarget has been added to DocGroup to handle the case
where an event is dispatched do DocGroup or when an AbstractThread is
created using a DocGroup. This means that we'll actually label more
events correctly with the DocGroup that they belong to.
DocGroups have also been moved to BrowsingContextGroup.

To correctly implement this, it must be known on instantiation whether E is
copy-constructible, which is not the case if only a forward declaration is
available. This can be resolved either by making sure a full definition of E is
available, which is preferable. But in cases where this is not (easily) possible,
the information can be explicitly provided by the MOZ_DECLARE_COPY_CONSTRUCTIBLE
and MOZ_DECLARE_NON_COPY_CONSTRUCTIBLE macros. In particular, declarations for
IPDL-declared types are added to nsTArray.h itself, like it was already done
for MOZ_DECLARE_RELOCATE_USING_MOVE_CONSTRUCTOR.

Splits WebGLContext into ClientWebGLContext and HostWebGLContext. The Client enables the JS-control of a WebGL context in a content procecss while the Host executes the WebGL graphics operations (via a WebGLContext that maintains much of the existing code) in the compositor process. At this point, the cross-process behavior is disabled -- this series of patches is an incremental step toward that final goal.

This patch suppresses VR device access permission prompts for users that do not have any VR runtimes installed.
We could not depend on the existing VR device enumeration functions to suppress the permission prompts, as the
act of enumerating VR devices will result in some hardware physically powering on and software starting up (and staying running)
in the background.
This patch includes logic to spawn the VR process with an additional flag indicating that it should attempt only to detect the
runtimes, without proceeding to enumerate and activate hardware and software.
VRManager now includes an enum to more clearly organize it's state machine model, which now must ensure that the runtime detection
happens on-demand when the VR session support capabilities are first determined.
There is a new pref to disable the suppression of permission prompts for use within permission UI tests on machines without VR runtimes.
Renamed some variables and added comments to make code in nsGlobalWindowInner and Navigator clearer and better represent the updated logic -- to allow the separate detection of VR runtimes and VR session activation. Both the runtime detection and VR
session activity uses VREventObserver to send events to nsGlobalWindowInner.

When JS is paused, VRService will automatically shutdown because the timer is not updated,
we used to create a new VRDisplay to JS. However, the page is still using the older VRDisplay,
so it can't get the newest VRDisplayInfo status. We should exit presentation and
apply the VRDisplayInfo status to the original VRDisplay instead of creating new one.
Besides, we also need to release the VR screen buffer after exiting the immersive mode to avoid eglMakeCurrent error.

This issue happens when VR/GPU haven't connected with the parent process via IPC protocol, and we are trying to access its IPC Child when it is still null. It is possible to be happened when GPU/VR process is killed/shutdown, and we are trying to launch a new VR process. We need to check these status before completing our VR process's launch.

This changes the way crash reports for child processes happening too early
during the child process' startup. Before bug 1547698 we wrote a partial
.extra file with those crashes that lacked the process type. The user would
not be notified of those crashes until she restarted Firefox and even when
submitted those crashes would be erroneously labeled as browser crashes.
After bug 1547698 we stopped writing .extra files entirely for those crashes
which left orphaned .dmp files among the pending crash reports.
This patch does three things to improve the situation:
* It writes a partial .extra file so that the crashes are detected at the next
startup. So the user is still not notified directly of these crashes but she
can report them later.
* It adds the process type to the .extra file so that the crash reporters are
labelled correctly.
* It fixes a leak in the `pidToMinidump` hash-map. Since the crashes were
not finalized the `ChildProcessData` strucutre associated with them would
never be fred.
