This commit removes the PRenderFrame protocol, while keeping the same ordering
and semantics of graphics IPC initialization.
To do this, some messages are added to PBrowser to simulate the constructor
and destructor of PRenderFrame. Messages that expected a nullable PRenderFrame
are updated to get a boolean instead.
One tricky area is the destruction of PRenderFrame. I've tried to keep it the
same as much as possible, but it's possible it might be slightly semantically
different than IPDL destruction. Destruction will be touched up in a later
patch, so I'm not too concerned.

Content process of Android uses sync IPC when initializing LookAndFeel. But
current e10s has LookAndFeel cache for start up of content process.
So we should use it, then remove sync IPC for start up performance

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.

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.

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.

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.

All prefs that need to be sent to a new content process are now put into the
shared memory segment, and they are identified by the pref name instead of an
index into a list. The old IPC used at process startup (in XPCOMInitData) is
removed.
Benefits:
- It removes the need for the early prefs list
(dom/ipc/ContentProcesses.{h,cpp}) and the associated checking, which is ugly
and often trips people up (e.g. bug 1432979, bug 1439406).
- Using prefnames instead of indices fixes some fragility (fixing bug 1419432).
- It fixes the problem of early prefs being installed as unlocked default
values even if they are locked and/or have user values.

ChildPrivileges is a leftover from the B2G process model; it's now
mostly unused, except for the Windows sandbox using it to carry whether
a content process has file:/// access.
In general, when sandboxing needs to interact with process launch, the
inputs are some subset of: the GeckoProcessType, the subtype if content,
various prefs and even GPU configuration; and the resulting launch
adjustments are platform-specific. And on some platforms (e.g., OS X)
it's all done after launch. So a simple enum used cross-platform isn't
a good fit.

Every JS plugin is assigned a unique ID. When an instance of a JS plugin is created the
frame loader that we use to load the plugin's handler URI will create a special
TabContext. This TabContext causes the ContentParent to use the process for this specific
JS plugin (creating one if it hasn't already) when it creates the PBrowser actors.
This causes the iframes for all the instances of a specific JS plugin to be grouped in the
same process.
