Replace it with NS_INTERFACE_MAP_BEGIN_CYCLE_COLLECTION, because it
has been the same for a while.

In some unknown circumstance, possibly if the parent process has a
different version than the child process, the child does not receive
scheduler prefs, which makes it read out of an uninitialized local
variable. This can probably happen because the scheduler prefs are
checked before we do the ContentChild::Init version check. Bill also
suggested that the pref env var might be getting truncated.
This patch improves on the situation by using null for the prefs array
if none was sent, and falling back on the default values, which leave
the scheduler disabled.
This also checks that the pref string is at least long enough to avoid
a buffer overflow. Note that if the end of the string isn't an integer
we'll end up with an sPrefThreadCount of zero, which can't be good.

When BudgetThrottlingEnabled transitions from true to false, the
execution budget can be negative which will have the unfortunate
effect of limiting the number of timeouts run by
TimeoutManager::RunTimeout to zero. By resetting the execution budget
in UpdateBudget, when BudgetThrottlingEnabled returns false, we
prevent this loop from happening.
WebRenderBridgeParent holds uninitialized mPipelineId when it was created by WebRenderBridgeParent::CreateDestroyed(). Then when CrossProcessCompositorBridgeParent::DeallocPWebRenderBridgeParent is called for the WebRenderBridgeParent, it will call EraseLayerState with some garbage uninitialized value, and so it will erase some random layer state entry.
The background thread hang monitor will crash Firefox after 60s if
a shutdown is too slow. Debug builds are slower and as such Marionette
would force kill Firefox right before the hang monitor can kick in.
