This patch moves remaining public `enum` of `nsIPresShell` to `mozilla`

Additionally, some methods which use the moving `enum`s from `nsIPresShell`

Jean-Yves Avenard e5f2be092a Bug 1540581 - P5. Add ColorSpace info to MacIOSurface. r=mattwoodrow
It would have been nicer and more logical to use a MacIOSurfaceImage to store the colorspace information, however the data passed around is a IOSurface Id via a SurfaceDescriptorMacIOSurface; the original data structure isn't kept; so we must transit the data at the same time as the IOSurface Id.

Also remove unnecessary test (new operator is infallible).

Jean-Yves Avenard 3ae43eb506 Bug 1493898 - P6. Move YUVColorSpace definition in the gfx namespace. r=mattwoodrow.
YUVColorSpace is inseparable from the bit depth as the matrix coefficients to be calculated need the bit depth information.

So let's put the two types together. gfx namespace also makes more sense as that's where we find IntRect, IntSize and other.

The extent of the changes highlight how much similar data structures are duplicated across the code, to the point it's scary.

Masayuki Nakano 9165a150a1 Bug 1540930 - Make nsPresContext use mozilla::PresShell directly rather than via nsIPresShell r=emilio
`nsPresContext` should use `mozilla::PresShell` directly instead of
`nsIPresShell`.  This patch makes it.

Unfortunately, `nsPresContext` and `nsIFrame` have `PresShell()`.  Therefore,
we cannot use `PresShell*` in its methods so that this patch uses `mozilla::`
namespace prefix.

It might be better to rename them as `PresShellPtr()` in another bug.

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.

Aaron Klotz 84c01f8930 Bug 1400344: Rename mscom::MainThreadRuntime to mscom::ProcessRuntime and make it aware of Win32k lockdown and of multiple instantiations; r=Jamie
This patch takes care of a bunch of issues and does some cleanup:

* We rename mscom::MainThreadRuntime to mscom::ProcessRuntime, as the latter
  is a more accurate name going forward.
* We make ProcessRuntime aware of the Win32k Lockdown process mitigation
  policy. When Win32k is disabled, we perform process-wide COM initialization
  in the multi-threaded apartment (since we cannot create an STA window).
* We refactor the mscom apartment region stuff to enable the Win32k lockdown
  pieces in ProcessRuntime.
* We move some Gecko-specific stuff into MOZILLA_INTERNAL_API guards so that
  ProcessRuntime is usable outside of xul.dll (I will be needing it for the
  launcher process).
* Another thing that might happen with the launcher process is that, under
  error conditions in the launcher, we create a ProcessRuntime object on a
  background thread for the purposes of telemetry logging, but we also allow
  the main thread to proceed to start as the browser. This could result in a
  scenario where the main thread, as the browser process, is attempting to
  instantiate its ProcessRuntime and ends up racing with the launcher process's
  telemetry thread which has its own ProcessRuntime. To account for this
  situation, we add mutual exclusion to the process-wide initialization code.
  We host this part inside mozglue since that state is shared between both
  firefox.exe and xul.dll.
* We clean up ProcessRuntime::InitializeSecurity by using Vector to set up
  the EXPLICIT_ACCESS entries.
* We remove mscom::MainThreadClientInfo and replace it with a direct call to
  CoGetCallerTID
* We revise all references to this class to use the new name.

Jed Davis bcff2dd108 Bug 1487287 - Synchronize GeckoChildProcessHost destruction with launching. r=mccr8
In order to enable asynchronous launch, destruction of
GeckoChildProcessHost (and its subclasses) has to be delayed until after
launching (or anything else that might be made asynchronous in the
future) has completed, to prevent use-after-free.  However, there are
other dependencies on process hosts always being destroyed on the I/O
thread, so refcounting would be difficult to use.

Instead, GeckoChildProcessHost now may not be destroyed directly, but
must go through a method that handles the scheduling.

There are also some minor cleanups to the affected headers (removed
duplicate access modifiers, and made PluginProcessParent final).

Nathan Froyd 9acf5a0c63 Bug 1517276 - thread callbacks through MemoryReportRequestClient; r=mccr8
The guts of MemoryReportRequestClient's supporting runnables contain
switches on the particular type of process we're running.  If you're
bringing up a new process type, having to add extra cases for your
process type here is a bit onerous.  These runnables really shouldn't
know anything about the process types that they're running on, either.

The easiest thing to do is modify MemoryReportRequestClient::Start to
take callbacks for what to do when a report is created and when
reporting is finished.  Then all process-specific knowledge can be
pushed out to the clients themselves, leaving MemoryReportRequestClient
and friends process-type agnostic.  We could even, at some later date,
move this code into xpcom/base/ to sit near nsMemoryReporterManager,
where it belongs.

Ryan Hunt 1601a8bb80 Bug 1453425 - Add relative scroll offset updates using nsGkAtoms::relative. r=botond
This commit adds a scroll origin, nsGkAtoms::relative, which can be used to
mark main thread scrolling that can be combined with a concurrent APZ scroll.

The behavior of this is controlled by a pref, apz.relative-update. This pref
is initially activated and is intended as an aid to narrowing down causes
of regressions for users in bug reports.

Relative scroll updates work by tracking the last sent or accepted APZ
scroll offset. This is sent along with every FrameMetrics. Additionally,
a flag is added to FrameMetrics, mIsRelative, indicating whether the
scroll offset can be combined with a potential APZ scroll. When this
flag is set, AsyncPanZoomController will apply the delta between the sent
base scroll offset, and sent new scroll offset.

This flag is controlled by the last scroll origin on nsGfxScrollFrame. The
new origin, `relative`, is marked as being able to clobber APZ updates,
but can only be set if all scrolls since the last repaint request or
layers transaction have been relative.
