PerformanceCounters are currently disabled in two ways:
- a preference that's off by default "dom.performance.enable_scheduler_timing"
- calls made only for nightly using #ifndef RELEASE_OR_BETA
In order to simplify the code, let's remove the #ifndef and rely only on the pref.
That will also allows us to use the feature in every version going forward.
The performance will not be impacted since the current code is already using
the (cached) pref value to determine if the counters are used.

ProtocolName() is only used for producing error messages and annotating
crash reports. But examining actual crash reports that would have used
the result of ProtocolName() indicates that we can always tell what the
erroring protocol is due to the stack backtrace. So having this virtual
function around just provides duplicate information, and it takes up too
much space in the vtable besides. Let's get rid of it.
This is necessary to avoid web platform test failures for tests that rely on layout calculations occurring
inside a recently opened tab or window. Originally, the layout flush was happening "accidentally" within
the StatusPanel that displays loading status for the browser. That flush is being removed in another patch
in this series.

This patch reverts parts of changeset e87e706def11 (bug 1425031).
The problem in bug 1425031 was that when the content process set a cookie
a notification was sent to the parent process. This notification was then
forwarded to all the content processes, including the one it originated from.
The solution was to not forward cookies that originated from a content
process, but this causes the current bug.
The correct fix is to forward the cookie changes to all content processes
except the one they originated from.
The test for bug 1425031 remains, and should keep passing.

This patch goes through and changes a bunch of places in our tree which mention
this bug to use the new feature, making the methods more strongly typed.
There are probably more places in tree which could be changed, but I didn't try

The current code is a bit of a mess. This patch does the following.
- Changes the processing from backwards to forwards. This avoids the need for
all the `found` booleans, because if a flag is present multiple times, the
last one will naturally override.
- Tightens up the checking. It now doesn't use assertions, but instead returns
false if any of the options are missing arguments, or have malformed
arguments, or any of the mandatory flags are missing. (It assumes that
-appdir and -profile are optional.)
- Renames the loop variable `idx` as `i`.
- Changes `!strcmp(...)` to `strcmp(...) == 0`, because I find that clearer.
- Avoids a redundant nsCString when handling -appdir.
The patch also tweaks GeckoChildProcessHost::mGroupId, which was buggy. It
holds the appModelUserId argument, which XRE_InitChildProcess() always expects
is present in the command. But it's only set to a non-empty value in
InitWindowsGroupID(), which is only called for plugin processes. So in lots of
cases the appModelUserId argument was missing, and a different argument would
be interpreted as the appModelUserId argument (seemingly without noticeable ill
effect).
The patch changes things to mGroupId defaults to "-", which means it's always
present in the command.
Note: all this explains why the old code for ContentProcess::Init() started
processing from argument aArgc, instead of aArgc-1 as you might expect -- it
had to read one extra arg in order to see the argument following -appdir,
because XRE_InitChildProcess() was decrementing aArgc for the appModelUserId
argument even when that argument wasn't present. The new code for
ContentProcess::Init() doesn't have to read past aArgc-1 because the mGroupId
fix ensures the appModelUserId argument is always present.

The new struct is in LayersTypes.h, all the rest of the changes are just
replacing existing uint64_t instances with the new LayersId struct.
Note that there is one functional change, in
CompositorBridgeParent::DeallocPWebRenderBridgeParent, where we now
correctly convert the PipelineId to a LayersId before using it to index
into sIndirectLayerTrees, whereas before we were incorrectly just using
the mHandle part of the PipelineId.

We're not using named shared memory, and supporting only anonymous
shared memory allows using other backends that are more compatible
with preventing a process from accessing any shared memory it wasn't
explicitly granted (i.e., sandboxing).
Specifically: SharedMemory::Open is removed; SharedMemory::Create no
longer takes a name, no longer has the open_existing option which doesn't
apply to anonymous memory, and no longer supports read-only memory
(anonymous memory which can never have been written isn't very useful).
This patch also fixes some comments in what remains of SharedMemory::Create.

All prefs that need to be sent to a new content process are now put into the
shared memory segment, and they are identified by the pref name instead of an
index into a list. The old IPC used at process startup (in XPCOMInitData) is
removed.
Benefits:
- It removes the need for the early prefs list
(dom/ipc/ContentProcesses.{h,cpp}) and the associated checking, which is ugly
and often trips people up (e.g. bug 1432979, bug 1439406).
- Using prefnames instead of indices fixes some fragility (fixing bug 1419432).
- It fixes the problem of early prefs being installed as unlocked default
values even if they are locked and/or have user values.

This remotes the APZInputBridge interface over the PAPZInputBridge
protocol in the case of the GPU process, and makes the GPU process'
main thread act as the APZ controller thread in that process. If
there is no GPU process we continue as before and the APZInputBridge
interface implementation is the concrete APZCTreeManager instance
in the UI process.
The main changes in this patch are moving all the code associated with
these messages out of APZCTreeManager{Parent,Child} and into
APZInputBridge{Parent,Child}. APZCTreeManagerChild now returns an
APZInputBridgeChild instance via InputBridge(), instead of returning
itself. The SetControllerThread call in the GPU process is also updated.

Bug #: 1444905
Differential Revision: https://phabricator.services.mozilla.com/D709
MozReview-Commit-ID: HIPDtHm6xpM
This patch replaces the large -intPrefs/-boolPrefs/-stringPrefs flags with
a short-lived, anonymous, shared memory segment that is used to pass the early
prefs.
Removing the bloat from the command line is nice, but more important is the
fact that this will let us pass more prefs at content process start-up, which
will allow us to remove the early/late prefs split (bug 1436911).
Although this mechanism is only used for prefs, it's conceivable that it could
be used for other data that must be received very early by children, and for
which the command line isn't ideal.
Notable details:
- Much of the patch deals with the various platform-specific ways of passing
handles/fds to children.
- Linux and Mac: we use a fixed fd (8) in combination with the new
GeckoChildProcessHost::AddFdToRemap() function (which ensures the child
won't close the fd).
- Android: like Linux and Mac, but the handles get passed via "parcels" and
we use the new SetPrefsFd() function instead of the fixed fd.
- Windows: there is no need to duplicate the handle because Windows handles
are system-wide. But we do use the new
GeckoChildProcessHost::AddHandleToShare() function to add it to the list of
inheritable handles. We also ensure that list is processed on all paths
(MOZ_SANDBOX with sandbox, MOZ_SANDBOX without sandbox, non-MOZ_SANDBOX) so
that the handles are marked as inheritable. The handle is passed via the
-prefsHandle flag.
The -prefsLen flag is used on all platforms to indicate the size of the
shared memory segment.
- The patch also moves the serialization/deserialization of the prefs in/out of
the shared memory into libpref, which is a better spot for it. (This means
Preferences::MustSendToContentProcesses() can be removed.)

Fuzzytime deterministically generates a random midpoint between two clamped values,
and if the unreduced timestamp is above the midpoint, the time is rounded upwards.
This allows safe time jittering to occur, as time will never go backwards on a given
timeline.
It _is_ possible for time to go backwards when comparing different (but related)
timelines, such as a relative timeline in one page (with its own
performance.timeOrigin) and a relative timeline in an iframe or Worker (which
also has its own performance.timeOrigin). This is the same behavior as the 2ms timer
reduction we previously landed; jitter doesn't make this any better or worse.
