This moves the code that detects very low memory scenarios and grabs memory
reports from the main thread event-loop to the available memory tracker.
Besides removing the overhead of the check from the event-loop code this
increases the likeliness of the reports being gathered by sampling at a
higher frequency but only when we already detected a low-memory scenario. Last
but not least this add checks for low commit-space detection alongside low
virtual-memory detection.

Have BrowsingContext keep its own cache to enable caching of
BrowsingContexts, especially in the parent process.
This isn't really optimal, since it effectively duplicates the
cache in the child process. BFcache keeps a list of strong pointers to
the list of cached nsDocShells, where each nsDocShell in turn keeps a
reciprocated strong pointer to its BrowsingContext, which in turn is
held in the BrowsingContexts list of cached contexts. Ideally these
caches should be merged.

Add BrowsingContext to allow the tree structure of docshells to exist
in several processes simultaneously. This is a first step towards
allowing a tree structure preserving separation of docshells across
processes.

We were previously failing to send blobs to new content processes, which was a
problem for those processes. But we were also attempting to extract blobs for
new entries that we were serializing after we'd extracted their structured
clone data, and their blob array had been thrown away (which was a problem for
all processes).
This patch fixes both problems.

Right now consumers can't know when the parent process has finished talking
to the permission manager. It would be nice to enable consumers to depend
on the status of the asynchronous task using a promise.

I was hoping to avoid supporting blobs here, but some parts of the
WebExtensions framework rely on being able to store Blobs in
initialProcessData, and can't be migrated without adding blob support.
This patch adds an ordered array of BlobImpls for all extant keys, clones them
to all child processes when updating the serialized maps, and initializes
StructuredCloneData instances with indexes into the combined array.

This class allows one read-write copy of a map in the parent process to share
data with multiple read-only copies in child processes. The maps only hold
onto data as structured clone blobs, and deserialize them each time a key is
read.
This commit only provides the bare-bones data structures. Follow-ups will add
bindings, change events, and automatic flushes.

This ChromeUtils API now returns a promise that gets resolved once all the data
has been collected via IPDL and the main process. The existing notification
design and its related XPCOM classes are removed.

Currently, in order to retrieve supported clipboard formats
DataTransfer::CacheExternalClipboardFormats repeatedly makes the same calls to
clipboard->HasDataMatchingFlavors.
In the case when aPlainTextOnly == true only 1 call is made -
clipboard->HasDataMatchingFlavors(kUnicodeMime, ...), and when
aPlainTextOnly == false we have 1 call made for every member of the list
{ kCustomTypesMime, kFileMime, kHTMLMime, kRTFMime, kURLMime, kURLDataMime,
kUnicodeMime, kPNGImageMime } - a total of 8 calls.
We can see that in nsClipboardProxy::HasDataMatchingFlavors, there is a call to
ContentChild::GetSingleton()->SendClipboardHasType.
So when aPlainTextOnly == true, we will have 1 sync message, and when
aPlainTextOnly == false, we will have 8 sync messages.
With the proposed solution, in DataTransfer::CacheExternalClipboardFormats
we will only have 1 sync message regardless of the case because
GetExternalClipboardFormats() will retrieve all supported clipboard
formats at once.

This new module simplifies how we interact with PerformanceInfo counters:
- CollectPerformanceInfo: returns all PerformanceInfo instances
- NotifyPerformanceInfo: converts PerformanceInfo in XPCOM and notify them

The new struct is in LayersTypes.h, all the rest of the changes are just
replacing existing uint64_t instances with the new LayersId struct.
Note that there is one functional change, in
CompositorBridgeParent::DeallocPWebRenderBridgeParent, where we now
correctly convert the PipelineId to a LayersId before using it to index
into sIndirectLayerTrees, whereas before we were incorrectly just using
the mHandle part of the PipelineId.
