* Remove redundant virtual keywords
* Mark all destructors of inheriting classes as virtual for clarity
* Mark all classes without virtual destructor as final (exposed errors)
* Make destructor virtual where it needed to be (some were missing)
* Replace empty ({}) code declaration in header with = default
* Remove virtual unused methods
I probably missed some, it quickly became a rabbit hole.

When the compositor thread has begun shutdown, it will spin the event
loop for the main thread until the last CompositorThreadHolder reference
has been released. While spinning, new IPDL objects may be attempted to
be created which depend on the compositor thread; we should check to
ensure the compositor thread is still around before proceeding with
creation. These objects include CompositorManagerParent,
ImageBridgeParent, and VRManagerParent. Additionally there is a very
similar bug between the vsync thread and VsyncBridgeChild.

clang's -Wmissing-prototypes option identifies global functions that can be made static (because they're only called from one compilation unit) or removed (if they're never called).

Sometimes NS_ASSERTION was hit during window closing. It happens because of aync architecture. It is better to change the NS_ASSERTION to NS_WARNING.

We report the number of frames dropped by the compositor because they were too late through:
ImageComposite -> ImageHost -> CompositableTransactionParent -> ImageBridgeParent -> IPDL -> ImageBridgeChild -> ImageContainerListener -> ImageContainer -> VideoSink

This was done automatically replacing:
s/mozilla::Move/std::move/
s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..

This code is unused now that ReadLockDescriptors are not sent in layer transactions.

This changes the lifecycle and API for TextureReadLock to fix file descriptor exhaustion
crashes. These changes are partially superficial and mostly align the API of TextureReadLocks
with their actual usage.
The changes are:
1. Create the TextureReadLock in the TextureClient constructor so it's available before IPC creation
a. This is superficial as EnableReadLock was always called before IPC creation
2. Send the ReadLockDescriptor in the PTextureConstructor message and close the file handle
3. Receive the ReadLockDescriptor in TextureHost and close the file handle
4. Send a boolean flag in layer transactions if the texture is read locked instead of a descriptor
5. Use a boolean flag in TextureHost to determine if the ReadLock must be unlocked instead of a nullptr
I believe that we can remove the InitReadLocks code from LayerTransaction as that was added to
prevent file descriptor limits in IPDL messages and is no longer needed with this change. But
that is a non-essential change and this patch is already big enough.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

This patch doesn't modify the mode lines at all -- it just swaps their order,
and makes each one its own C++ comment, separate from the MPL boilerplate
comment.

From the crashes associated with bug 1389021, we know that some
compositor thread IPDL owners are not being cleaned up properly. We do
not know which protocols are causing the problem, so we temporarily will
annotate the logs with the ownership status. This should be limited to
under a dozen instances of the protocols.
This change will be backed out after a few builds are produced with it
and we see the first crash reports with the relevant data.

We currently allow the content process to shutdown the IPDL objects on
behalf the parent, and we wait for all of these instances to be freed
before we complete shutdown. This is undesirable because it requires the
parent to trust the child rather than the other way around; the child
can hold shutdown hostage by simply not releasing its instances. The
child should already support the parent closing its graphics IPDL
objects because the GPU process itself can die abruptly and be restored
at a later time.

When WebRender creation is failed, WebRender is disabled in gecko. There is a case that WebRenderBridgeParents exist when WebRender is disabled. To handle this, gecko needs to rebuild all CompositorSessions.
There is also a problem related to gfxVars::UseWebRender on compositor thread. If e10s is enabled, but no-gpu process(default on linux and mac), gfxVars::UseWebRender change is soon notified by compositor thread tasks. If WebRender creation failure happens at 2nd WebRender creation, several WebRenderBridgeParents for 1st WebRender could exist. IPC messages from WebRenderLayerManager are normally async, then there is a chance that the WebRenderBridgeParents receive the messages after the gfxVars::UseWebRender change. Further the gfxVars::UseWebRender change in content process could be delayed than WebRenderBridgeParents, then content process does not have a way to stop sending PWebRenderBridge IPC until the change of gfxVars::UseWebRender is received. WebRenderBridgeParent related tasks handle the message, but some tasks are done based on gfxVars::UseWebRender. At this time, gfxVars::UseWebRender returned false on compositor thread, then it cause unexpected result for WebRenderBridgeParent and WebRender. To addres this inconsistent situation, WebRenderBridgeParent related tasks on compositor thread stop to use gfxVars::UseWebRender.
We will use the new type for the generated IPDL message handler
prototype to make sure correct error handling method is called.
