Summary:
We currently have a single WebAuthnManager instance per process that's shared
between all CredentialContainers. That way the nsPIDOMWindowInner parent has
to be tracked by the transaction, as multiple containers could kick off
requests simultaneously.
This patch lets us we have one WebAuthnManager instance per each
CredentialsContainer and thus each nsPIDOMWindowInner. This matches the current
U2F implementation where there is one instance per parent window too.
This somewhat simplifies the communication diagram (at least in my head), as
each U2F/WebAuthnManager instance also has their own TransactionChild/Parent
pair for IPC protocol communication. The manager and child/parent pair are
destroyed when the window is.

If QueryHandlerInterface returns E_NOINTERFACE, the proxy will be queried for the interface.
However, the handler might know that the interface is definitely not available and could thus avoid a pointless cross-process call.
To facilitate this, the handler can now return S_FALSE to signal that the proxy should not be queried, thus immediately returning E_NOINTERFACE to the client.

Currently if you write an async IPDL method which has a return value, we expose
a SendXXX method which returns a MozPromise. This MozPromise can then be
->Then-ed to run code when it is resolved or rejected.
Unfortunately, using this API loses ordering guarantees which IPDL provides.
MozPromise::Then takes an event target, which the resolve runnable is dispatched
to. This means that the resolve callback's code doesn't have any ordering
guarantees relative to the processing of other IPC messages coming over the same
protocol.
This adds a new overload to SendXXX with two additional arguments, a lambda
callback which is called if the call succeeds, and a lambda callback which is
called if the call fails. These will be called in order with other IPC messages
sent over the same protocol.

StripHandlerFromOBJREF shortens the OBJREF by sizeof(CLSID), so it needs to seek the stream back after tweaking the OBJREF.
Previously, this was done using a relative seek.
Unfortunately, for some reason I can't fathom on Windows 7, this doesn't work when marshaling for VT_DISPATCH.
The Seek call succeeds, but either does nothing or sets the stream position to a garbage value.
Instead, we now use an absolute seek, which seems to behave.
This was breaking IAccessible::accNavigate and AccessibleChildren on Windows 7.

The second field is the duration, in microseconds, of time spent actually

ChildPrivileges is a leftover from the B2G process model; it's now
mostly unused, except for the Windows sandbox using it to carry whether
a content process has file:/// access.
In general, when sandboxing needs to interact with process launch, the
inputs are some subset of: the GeckoProcessType, the subtype if content,
various prefs and even GPU configuration; and the resulting launch
adjustments are platform-specific. And on some platforms (e.g., OS X)
it's all done after launch. So a simple enum used cross-platform isn't
a good fit.

Currently the Gecko Profiler defines a moderate amount of stuff when
MOZ_GECKO_PROFILER is undefined. It also #includes various headers, including
JS ones. This is making it difficult to separate Gecko's media stack for
inclusion in Servo.
This patch greatly simplifies how things are exposed. The starting point is:
- GeckoProfiler.h can be #included unconditionally;
- everything else from the profiler must be guarded by MOZ_GECKO_PROFILER.
In practice this introduces way too many #ifdefs, so the patch loosens it by
adding no-op macros for a number of the most common operations.
The net result is that #ifdefs and macros are used a bit more, but almost
nothing is exposed in non-MOZ_GECKO_PROFILER builds (including
ProfilerMarkerPayload.h and GeckoProfiler.h), and understanding what is exposed
is much simpler than before.
Note also that in BHR, ThreadStackHelper is now entirely absent in
non-MOZ_GECKO_PROFILER builds.
Avoid going through GeckoAppShell and move the start child process JNI
call directly to GeckoProcessManager.

Each protocol in IPDL has a bunch of autogenerated functions that
instantiate IPC::Message with various parameters. Each of these
functions, then:
1) Pays the cost of calling malloc()
2) Setting up various parameters
3) Calling IPC::Message()
There's no reason that we should be duplicating 1) across all of these
autogenerated functions. In step 2), several of the parameters we're
setting up are common across all or nearly all calls: the message
segment size is almost always zero, and we're always indicating that
IPDL-generated messages should be recorded in telemetry.
Instead of duplicating that code several thousand times, we can add a
small helper function that takes the only interesting parameters for an
IPDL message. This helper function can then deal with calling malloc in
a single place and setting up the common parameters. For messages that
require a custom segment size, we'll have to use the old scheme, but
such messages are uncommon.
The previous changes are not required for this scheme to work, but they
do help significantly, as the helper function (Message::IPDLMessage) can
now take four parameters, which ensures that its arguments are passed
solely in registers on Win64 and ARM. The wins from this change are
also larger than they would be without the previous parts: ~100K on
x86-64 Linux (!) and ~80K on ARM Android.
The current IPC::Message constructor takes a large number of arguments,
three of which--the nesting level, the priority, and the
compression--are almost always constant by virtue of the vast majority
of Message construction being done by auto-generated IPDL code. But
then we take these constant values into the Message constructor, we
check them for various values, and then based on those values, we
perform a bunch of bitfield operations to store flags based on those
values. This is wasted work.
Furthermore, for replies to IPDL messages, we'll construct a Message
object, and then call mutating setters on the Message object that will
perform even more bitfield manipulations. Again, these operations are
performing tasks at runtime that are the same every single time, and use
information we already have at compile time.
The impact of these extra operations is not large, maybe 15-30K of extra
code, depending on platform. Nonetheless, we can easily make them go
away, and make everything cleaner to boot.
This patch adds a HeaderFlags class that encapsulates all the knowledge
about the various kinds of flags Message needs to know about. We can
construct HeaderFlags objects with strongly-typed enum arguments for the
various kinds of flags, and the compiler can take care of folding all of
those flags together into a constant when possible (and it is possible
for all the IPDL-generated code that instantiates Messages). The upshot
is that we do no unnecessary work in the Message constructor itself. We
can also remove various mutating operations on Message, as those
operations were only there to support post-constructor flag twiddling,
which is no longer necessary.
There's no need to be repeating 'IPC::Message::' prefixes or spreading
around more ExprVar calls than we need here. Let's try to improve the
signal-to-noise ratio of this code by introducing a helper function to
inject some of the boilerplate for us.
_generateMessageConstructor takes a lot of `md.FOO`-style parameters,
which could be derived inside the function by simply passing `md`.
Especially with the upcoming changes to calculate things like reply-ness
of messages, sync-ness, etc, we'd be wanting to pass even more
parameters like `md.FOO`. So let's just pass `md` in, and then we can
make all the necessary future changes in a single place.
The GPU process doesn't have the directory service enabled, so it can't find
a tmp dir to put its .extra files for crash reports. Even if we do enable the
directory service, we still don't get the correct "content process tmp dir" in
the GPU process, because the UUID baked into that folder is passed via the
preferences service, and that isn't initialized in the GPU process either.
Rather than unneccessarily initialize all this stuff in the GPU process just
to get one folder name, we can pass that folder name directly in the argv list.

Since NoFocusState is am empty struct used in the |mData| variant in

inheritting from EmptyStructSerializer for the NoFocusState specialization.

It's important that shmem creation/destruction messages be ordered
correctly with respect to other messages that use shmems. For example,
if we create a shmem with ID 10 and then send a message that
references shmem 10, then the creation message must be handled before
the referencing message. If shmem creation/destruction messages go in
a separate queue from other messages, this ordering may not be
preserved.
Leaving shmem creation/destruction unlabeled will give us the correct
ordering. Eventually, though, we'll need to provide a solution that
doesn't bottleneck the event queue.
