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.

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.
Never store names in Message. One can get string names from

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 nsIU2FToken and its implementors are no longer needed; the soft token was
re-implemented into dom/webauthn/U2FSoftTokenManager.cpp during the WebAuthn
implementation. When the dom/u2f/ code changed to the implementation from
WebAuthn, the old synchronous version became dead code.
This patch removes the dead code.

Certain types (such as Shmem and Endpoint types) cannot be copied, and need to
be moved when passed around. When used with MozPromises, that means that the
promise needs to be non-shareable, and the resolve functions need to use the
