When PluginInstanceChild receives native key events, it should post the events to the chrome process first for checking if the key combination is reserved. However, posting all key events to the chrome process may make damage to the performance of text input. Therefore, this patch starts to post a key event whose key combination may be a shortcut key. However, for avoiding to shuffle the event order, it posts following key events until all posted key events are handled by the chrome process.
For receiving response from widget, this patch defines nsIKeyEventInPluginCallback. It's specified by nsIWidget::OnWindowedPluginKeyEvent() for ensuring the caller will receive the reply. Basically, the caller of nsIWidget::OnWindowedPluginKeyEvent() should reply to the child process. However, if the widget is a PuppetWidget, it cannot return the result synchronously. Therefore, PuppetWidget::OnWindowedPluginKeyEvent() returns NS_SUCCESS_EVENT_HANDLED_ASYNCHRONOUSLY and stores the callback to mKeyEventInPluginCallbacks. Then, TabParent::HandledWindowedPluginKeyEvent() will call PuppetWidget::HandledWindowedPluginKeyEvent().

I also add some missing data to the content version, namely the duration of time that ContentParent::SendLoadPlugin takes.

mContentParent is really just to be used while handling a synchronous
ContentParent::RecvLoadPlugin call when async plugin init turned on.
In any other context, using it will be unsafe.
This patch adds comments and assertions to ensure that this value isn't set
otherwise, and converts the one use of mContentParent outside of async plugin
init to use an alternative mechanism for identifying the content process.

When turned on e10s, plugin process creates from chrome process. So content
process doesn't know current sandbox level. To rewrite wmode attribute on
contnet process by sandbox level >= 2, we should store sandbox level to
nsPluginTag.

Experience shows that we do not have enough profiler labels to make
BHR hang reports meaningful. This patch adds enough labels to let us
exploit hang reports matching the 25 topmost chrome hangs.

We need to let ContentParent and PluginModuleParent get a reference to the ProfileGatherer
during the window of time that we're profiling so that if they start to die (the actor is
starting to go away), they have a gatherer they can send their last profile data to.
The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

A lot of existing code has variations on:
if (ManagedPFooChild().Length()) {
...(ManagedPFooChild()[0])...
}
// Do something with nullptr, or some other action.
It's pretty reasonable to repeat this code when the managed protocols
are stored in an array; the code gets much less nice when managed
protocols are stored in a hashtable. Let's write a small utility
function to handle those details for us. Then when we change the
underlying storage, we only need to update this function, rather than a
bunch of callsites.
ProtocolUtils.h is included by all the generated IPDL headers, so
LoneManagedOrNull should be available everywhere the above pattern would
be encountered.
