These are all easy cases where an nsXPIDLCString local variable is set via
getter_Copies() and then is only used in ways that nsCStrings can also be used
(i.e. no null checks or implicit conversions to |char*|).
In every case the patch trivially replaces the nsXPIDLCString with an
nsCString. (Also, there are a couple of unused nsXPIDLCString variables that
the patch simply removes.)
This patch refactors the nsThread event queue to clean it up and to make it easier to restructure. The fundamental concepts are as follows:
Each nsThread will have a pointer to a refcounted SynchronizedEventQueue. A SynchronizedEQ takes care of doing the locking and condition variable work when posting and popping events. For the actual storage of events, it delegates to an AbstractEventQueue data structure. It keeps a UniquePtr to the AbstractEventQueue that it uses for storage.
Both SynchronizedEQ and AbstractEventQueue are abstract classes. There is only one concrete implementation of SynchronizedEQ in this patch, which is called ThreadEventQueue. ThreadEventQueue uses locks and condition variables to post and pop events the same way nsThread does. It also encapsulates the functionality that DOM workers need to implement their special event loops (PushEventQueue and PopEventQueue). In later Quantum DOM work, I plan to have another SynchronizedEQ implementation for the main thread, called SchedulerEventQueue. It will have special code for the cooperatively scheduling threads in Quantum DOM.
There are two concrete implementations of AbstractEventQueue in this patch: EventQueue and PrioritizedEventQueue. EventQueue replaces the old nsEventQueue. The other AbstractEventQueue implementation is PrioritizedEventQueue, which uses multiple queues for different event priorities.
The final major piece here is ThreadEventTarget, which splits some of the code for posting events out of nsThread. Eventually, my plan is for multiple cooperatively scheduled nsThreads to be able to share a ThreadEventTarget. In this patch, though, each nsThread has its own ThreadEventTarget. The class's purpose is just to collect some related code together.
One final note: I tried to avoid virtual dispatch overhead as much as possible. Calls to SynchronizedEQ methods do use virtual dispatch, since I plan to use different implementations for different threads with Quantum DOM. But all the calls to EventQueue methods should be non-virtual. Although the methods are declared virtual, all the classes used are final and the concrete classes involved should all be known through templatization.

When creating new windows/tabs from the content process, we currently choose
the default remote type based on the referrer URI, rather than the actual
remote type of the opener. While this generally works, it fails when opening
windows from URLs (particularly in iframes) which are opened in process types
other than their default process type, since the initial about:blank load gets
redirected to a new process before the child process has a chance to load its
actual target URI.
Using the actual remote type of the child opening the window fixes this
problem for URLs which are capable of being loaded into the child's process
type.

Telemetry has indicated that preference update messages are one of the
most common unlabeled runnables. Starting the browser on a clean
profile and letting it just sit for a few minutes shows many prefs being
broadcast to all content processes that won't really have any effect on
said content processes--preference changes having to do when services
were last checked for updates and things like that. To cut down on
preference update traffic, this patch introduces a simple blacklist
against which all preference updates are compared. This should cut down
on preference update traffic and reduce the number of unlabeled
runnables to worry about.

In all of these cases the fixed buffer has the same lifetime as the string
object, so we can use nsAuto[C]String for simplicity.
For the 128-length ones in dom/xul/ I just switched to the default of 64 for
simplicity, because the choice of 128 didn't seem that important. (These code
paths weren't hit when I started the browser and opened a few sites.)
Finally, the patch also changes LoggingIdString to use
nsAutoCStringN<NSID_LENGTH>, similar to NullPrincipalURI.
Without this patch, all remote process types share a process name of
"Web Content". With this patch, specific names are added for "file",
"extension", and "webLargeAllocationTypes", with the default of "web"

This patch also eliminates undocumented b2g-era legacy logic that had a
notion of whether it's acceptable to override the process name. In the
b2g era, I believe processes were named based on the "app" that was
running. It would have made sense to have the process initially named
the preallocated process, then to change the process to its app name
when specialized, trying to make it hard/impossible for the process to
rename itself so it couldn't masquerade as another app if it became
compromised.

Android now supports telling an IME that it shouldn't store user-entered content into it's dictionary/language model/etc. and we want to automatically enable this in private browsing.
As the code that handles input on Android doesn't have any notion of tabs (and therefore of the difference between normal and private tabs), the best way to get that info across is to retrieve it directly within the IMEStateManager from the corresponding document and store it in the inputContext, which is then passed to Java for Fennec to handle.
Implementing this within Gecko also has the benefit that this part of the code can be used by other platforms as well should they want to support similar features in the future.

Currently, access key is handled in EventStateManager::PreHandleEvent() with eKeyPress event, i.e., before dispatching it into the DOM tree, if the access key is registered in EventStateManager. So, the main process does not check if the preceding eKeyDown event is consumed in focused remote process.
When preceding eKeyDown event is consumed in the main process, eKeyPress event won't be dispatched by widget. However, if remote process has focus, it's impossible widget to stop dispatching eKeyPress event because preceding eKeyDown event hasn't been handled in the focused remote process yet. Therefore, main process needs to post eKeyPress event to check if preceding eKeyDown event was consumed. When eKeyPress event is marked as "waiting reply from remote process", TabChild sends it back to the main process only when preceding eKeyDown event wasn't consumed. So, only when eKeyPress event is back to the main process, main process should handle accesskey with it.
This patch makes EventStateManager::PreHandleEvent() check if a remote target has focus before handling accesskey. If a remote process has accesskey and there is an accesskey matching with eKeyPress event, it marks the event as "waiting reply from remote content" and stop propagation in the process.
Finally, when eKeyPress event is sent back to TabParent, TabParent::RecvReplyKeyEvent() calls EventStateManager::HandleAccessKey() before dispatching the reply event into the DOM tree.

This patch makes the following changes to the macros.
- Removes PROFILER_LABEL_FUNC. It's only suitable for use in functions outside
classes, due to PROFILER_FUNCTION_NAME not getting class names, and it was
mostly misused.
- Removes PROFILER_FUNCTION_NAME. It's no longer used, and __func__ is
universally available now anyway.
- Combines the first two string literal arguments of PROFILER_LABEL and
PROFILER_LABEL_DYNAMIC into a single argument. There was no good reason for
them to be separate, and it forced a '::' in the label, which isn't always
appropriate. Also, the meaning of the "name_space" argument was interpreted
in an interesting variety of ways.
- Adds an "AUTO_" prefix to PROFILER_LABEL and PROFILER_LABEL_DYNAMIC, to make
it clearer they construct RAII objects rather than just being function calls.
(I myself have screwed up the scoping because of this in the past.)
- Fills in the 'js::ProfileEntry::Category::' qualifier within the macro, so
the caller doesn't need to. This makes a *lot* more of the uses fit onto a
single line.
The patch also makes the following changes to the macro uses (beyond those

- Removes a useless PROFILER_LABEL use within a trivial scope in

any useful purpose. It also serves as extra evidence that the AUTO_ prefix is
a good idea.

The test added to test_crash_service.js covers computing the minidump SHA256
hash (bug 1322611) and of the minidump analyzer itself (bug 1280477).

This event is no longer necessary, since checking nsITabParent.hasPresented is enough to know
if we need to blank out the tab or not.

If the "security.sandbox.content.level" preference is set to a value less than
1, all consumers will automatically treat it as if it were level 1. On Linux and
Nightly builds, setting the sandbox level to 0 is still allowed, for now.

Originally the pref is called security.data_uri.inherit_security_context, so the pref is default on.
And when we finish this feature, we turn it off.
To avoid causing confusion in the future, perhaps we should rename it and make the pref default off.
Switching to Telemetry::ProcessID allows us to break out extension process data from the content process data.

Removing support for this preference means that mReuseLoaderGlobal
will always be false, which lets us eliminate that field, and remove a
lot of code.
This also means that false is always passed to
PrepareObjectForLocation for aReuseLoaderGlobal.
ReadCachedFunction is no longer used, so it is deleted.

PBrowser::RequestNativeKeyBindings() is used only when somebody tries to
execute native key bindings for synthesized keyboard events. Therefore, it
doesn't need to retrieve edit commands for all editor types. Instead, it
should take the editor type and just return the edit commands for it.

Now, nsIWidget::ExecuteNativeKeyBinding() isn't used by anybody for executing
edit commands. Instead, they need array of edit commands for the key
combination. So, the method should be renamed to GetEditCommands() and just
return edit commands as an array.

When eKeyPress event is dispatched from TabParent to a remote process, it
should store edit command for all editor types. Then, copied
WidgetKeyboardEvent in the remote process doesn't need to request the edit
commands when its ExecuteEditCommands() is called.
Note that this patch also changes a automated test, browser_bug1316330.js,
that uses nsIDOMWindowUtils.dispatchDOMEventViaPresShell() to dispatch
repeated keyboard events in the tab. However, it should use synthesizeKey()
to emulate everything of native keyboard events and the API can dispatch
repeated keyboard events too. (And the test has a bug. It tries to wait 0.5
sec when every keydown or keypress event. However, it fails since startTime
is never initialized. This patch fixes this bug too.)

This function is arguably nicer than calling NS_ProcessNextEvent
manually, is slightly more efficient, and will enable better auditing
for NS_ProcessNextEvent when we do Quantum DOM scheduling changes.
