This adds a basic StringBundle implementation using shared memory maps, but
doesn't yet hook them up to anything. They behave the same as ordinary string
bundles, but have the additional restriction that they are permanent for the
length of the session, and cannot be removed from the cache.

This class implements a shared memory key-value store that fits into a single
memory mapped segment. All of the runtime data for its instances are stored in
the shared memory region, which means that memory overhead for each instance
in each process is only a few bytes.
Importantly, the key and value strings returned by this class are also
pointers into the shared memory region, which means that once an instance is
created, its memory cannot be unmapped until process shutdown.
For the uses I intend to put it to, this is a reasonable constraint. If we
need to use it for shorter-lived maps in the future, we can add an option to
return non-literal dependent strings that will be copied if they need to be
kept alive long term.

This class allows us to map a read-write shared memory region, and then safely
remap it read-only, so that it can be shared with sandboxed content processes.

Currently, if an event is consumed in the main process, EventStateManager
does not send it to remote process. However, this is unexpected behavior
for some WidgetKeyboardEvent dispatchers. OS sometimes has consumed native
key events before sending applications. For example, Alt key on Windows
should activate menu bar of focused window but Alt key may be consumed before
focused window receives the event. In such case, we mark Alt keyboard event
as "consumed before dispatch", and chrome treat it like as its preventDefault()
is called in web content. (Note that for compatibility with other browsers,
the consumed state is not exposed to web content. So, Event.defaultPrevented
returns false in web content.)
Therefore, we need to treat "consumed" state and "cross process forwarding"
state separately. This patch makes calling WidgetEvent::PreventDefault()
always stops cross process forwarding for backward compatibility. Additionally,
for the special case mentioned above, this patch makes
WidgetEvent::PreventDefaultBeforeDispatch() take additional argument,
|aIfStopCrossProcessForwarding|. If this is CrossProcessForwarding::eStop,
the event won't be sent to remote process as same as calling PreventDefault().
Otherwise, CrossProcessForwarding::eHold, PreventDefaultBeforeDispatch() call
does not change "cross process forwarding" state. I.e., if the event's
StopCrossProcessForwarding() and PreventDefault() are not called until
EventStateManager::PostHandleEvent(), the event will be sent to remote process
as usual.

This is a quick-and-dirty port. It might be nice to replace
SpecialPowersObserver with the webextensions content script injection
system at some point, but that isn't practical right now (since WE experiments
cannot implement new APIs visible to content scripts).

Summary:
This moves the load of favicons into the content process. We use the same logic
for finding favicons (based on waiting until none have shown up for a short
time) but then load the favicon and convert it to a data uri which we then
dispatch to the parent process. Along the way this fixes asssociating the load
with the tab for WebExtension and devtools, fixes CSP usage for the load, fixes
expiry detection of the favicon and stops us from loading the same resource
twice.
This change also merges the prefs browser.chrome.site_icons and
browser.chrome.favicons leaving just the former controlling favicon loading. It
adds the pref browser.chrome.guess_favicon to allow disabling guessing where
a favicon might be located for a site (at <hostname>/favicon.ico). This is
mainly to allow disabling this in tests where those additional yet automatic
requests are uninteresting for the test.
There are multiple clean-ups that can follow this but this is a first step along
that path.

We cannot simply pass the status code using nsIWebSocketListener::OnServerClose because it's called only when the connection is established. Instead, I'm passing TLS failure from http channel to nsIWebSocketListener::OnStop where the correct status code is set.
This will make sure that when running |mach python-test --python 3| locally,
we only run the tests that also run in CI with python 3 (and therefore pass
presumably).

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.

Some MSE streams will resend the same init segment. In these cases we can treat
the following data as belonging to the already existing stream. We do this by
reusing the same stream id. This stops us tearing down and restarting decoders
in these cases. This has the benefit of stopping us introducing gaps to audio
and/or video.

In bug 1364624 we switched over to SRWLock on Windows for our internal
implementation of mozilla::Mutex. This doesn't allow for re-entrancy. The
WebCryptoThreadPool shutdown code has potential for re-entrancy due to the
spinning of the main thread event loop while shutting down the worker threads.
By limiting the scope of the lock protecting mPool during shutdown we can avoid
the re-entrancy. Addtionally we track the shutdown status to avoid dispatching
events once shutdown has started.

It's possible that if the HTMLMediaElement is loading while we're loading a new
document into a docshell, that the HTMLMediaElement can reach readyState
HAVE_FUTURE_DATA just after its OwnerDoc is removed from the docshell. If the
HTMLMediaElement wasn't paused, then it may start playing due to the readyState
change in HTMLMediaElement::ChangeReadyState().
For years we've had hard to reproduce issues where media started playing after
we've closed the tab; I bet this was the cause!
When we detect that the document has been removed from its DocShell,
HTMLMediaElement::NotifyOwnerDocumentActivityChanged() is called, and that
suspends the MediaDecoder just in case we need to resurrect the media element,
for example if the tab comes out of the BF cache. When we suspend we set
mPausedForInactiveDocumentOrChannel=true, and all other calls to
MediaDecoder::Play() are guarded by checks on
mPausedForInactiveDocumentOrChannel.
So we should also guard the MediaDecoder::Play() call in ChangeReadyState()
with a check on mPausedForInactiveDocumentOrChannel too.
