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.

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 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 patch was reviewed in parts, however the intermediate states would not build:
Bug 1443954 - Part 3A: Strip pointers from the argument to WriteParam and WriteIPDLParam before selecting the ParamTraits impl, r=froydnj
Bug 1443954 - Part 3B: Move nsIAlertNotification serialization to the refcounted system, r=bz
Bug 1443954 - Part 3C: Move geolocation serialization to the refcounted system, r=bz
Bug 1443954 - Part 3D: Move nsIInputStream serialization to the refcounted system, r=baku
Bug 1443954 - Part 3E: Move BlobImpl serialization to the refcounted system, r=baku
Bug 1443954 - Part 3F: Correctly implement ParamTraits for actors after the ParamTraits changes, r=froydnj
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.

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.

Content processes can contain ghost windows, so the debug-only ghost
window unlinker needs to send a message to child processes to get them
to run it, too.
