This patch started life as making ImageEncoder.cpp:EncodingRunnable not
use nsAutoArrayPtr, but the API effects rippled out from there. On the
whole, I think using UniquePtr throughout has made the code clearer.
Right now we call disposeNative on GeckoEditable in the
nsWindow::Natives destructor. However, we may still have pending native
calls in the event queue at that point, and these events will cause
exceptions when handled. This patch makes GeckoEditable call
disposeNative, after ensuring there's no pending calls.
GeckoEvent.KEY_EVENT and GeckoEvent.IME_EVENT used to count as UI events
for the hang monitor. We should count the new native calls as native
events too through this patch.
Move the IME event handler implementation in nsWindow::OnIMEEvent to
individual native calls in nsWindow::Natives. This patch also moves most
member variables and helper functions related to IME to inside
nsWindow::Natives. This has the benefit of better organization and saves
some memory because only the top-level nsWindow now keeps IME states.
GetIMEComposition and RemoveIMEComposition are kept inside nsWindow
because they are not strictly related to IME events, and they are used
by some other event handlers in nsWindow.
In the period after nsWindow is destroyed, but before disposeNative is
called, we should discard any pending native calls. These calls would
result in exceptions anyways because the nsWindow weak pointer is now
null. After disposeNative is called, any native calls will still result
in exceptions because in that case, it's Java code's responsibility to
ensure that calls are not made after disposeNative is called.
This patch adds a separate close() call to nsWindow, and let the
GeckoView decide whether to make that call or not. This lets us use the
static version of disposeNative. If nsWindow is destroyed in the
meantime, we still want to call disposeNative, which would only be
possible using the static version of disposeNative.
It's helpful to have a static DisposeNative when disposing of instances
that are still associated with a native object through an null weak
pointer. In that case, we can't call instance methods because the weak
pointer is null, but we can still call static methods.
This patch implements a new key event handler in nsWindow to replace the
previous implementation.
nsWindow::HandleSpecialKey was removed because it's a relic from XUL
Fennec and I believe we no longer need it for native Fennec.

part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.
