The vast majority of the virtual methods which were used on ProtocolState were
actually methods which only had meaningful implementations on the toplevel
protocol. This patch adds a new field to IProtocol holding a direct pointer to
the protocol's `IToplevelProtocol`, and the methods formerly implemented with
ProtocolState now directly call the corresponding method on IToplevelProtocol.
IToplevelProtocol then shadows these methods with the toplevel protocol
implementation, meaning that the right code is run in the right places.
In addition, some state was maintained for protocols inside of the separate
ProtocolState allocation, and this patch moves that state back into the actor
itself.

Historically we've failed very loudly when receiving a message which was
destined for an actor which had already been destroyed. This had the
effect of requiring manual teardown for most actors, as work would need
to be done to ensure messages weren't sent when the target actor might
be about to tear itself down.
In addition, due to this teardown work being done outside of IPDL, this
work would have to manually be checked in subactors, and involved the
addition of new flags, such as `mIPCOpen`, in order to track whether IPC
had begun to be shut down, and discard messages manually if it had.
It is an ongoing issue that we occasionally miss places where we need to
discard messages, and it is easy to not remember to perform async
destruction when building a new actor, meaning that extra work is
required to correctly discard messages when the actor is being torn
down. Due to the correct decision, almost all of the time, being to
discard the message, this patch takes the approach of transforming the
crash which was previously performed into a message discard.
The hope is that this will reduce the burden on actor implementors, by
allowing the use of `Send__delete__` without first synchronizing with
the remote actor, as well as reduce unintentional crashes.

There's now an upper limit for snapshot prefilling. The value is configurable and is currently set to 4096 bytes.
Snapshots can operate in multiple modes depending on if all items have been loaded or all keys have been received. This should provide the best performance for each specific state.
This patch also adds support for creating explicit snapshots which can be used for testing.
This improves performance a lot in cases when multiple operations are invoked by a single JS function (number of sync IPC calls is reduced to a minimum). It also improves correctness since changes are not visible to other content processes until a JS function finishes.
The patch implements core infrastructure, all items are sent to content when a snapshot is initialized and everything is fully working. However, sending of all items at once is not optimal for bigger databases. Support for lazy loading of items is implemented in a following patch.
The implementation is based on a cache (datastore) living in the parent process and sync IPC calls initiated from content processes.
IPC communication is done using per principal/origin database actors which connect to the datastore.
The synchronous blocking of the main thread is done by creating a nested event target and spinning the event loop.

This patch adds the ability to use UniquePtr<T> in IPDL messages if T is serializable. The behavior works as expected -- a UniquePtr in a Send is cleared and is passed by move.
Some design points:
* The UniquePtr identification is done in the parser. This is because the parser immediately normalizes CxxTemplateInst -- an old version of the patch did hacky string-parsing to pull it apart. I, instead, created CxxUniquePtrInst.
* The implementation allows passing to Send... by move or by reference. This is valid UniquePtr API behavior but passing by reference is not really useful in this case (but not harmful).

The framework to simulate the setting change works as following;
- nsIDOMWindowUtils.setPrefersReducedMotion() calls an IPC function which ends
up calling nsChildView::SetPrefersReducedMotion() in the parent process
- nsChildView::SetPrefersReducedMotion() sets the given value into
nsLookAndFeel::mPrefersReducedMotionCached just like we set the value queried
via NSWorkspace.accessibilityDisplayShouldReduceMotion in the parent process
and send a notification which is the same notification MacOSX sends when the
system setting changed
- Normally the cached value is cleared before quering new values since the
cache value is stale, but in this case the value is up-to-date one, so
nsChildView::SetPrefersReducedMotion() tells that we don't need to clear the
cache, and nsIDOMWindowUtils.resetPrefersReducedMotion() resets that state
of 'we don't need to clear the cache'
There are two test cases with the framework in this commit, one is just setting
the value and checking the value queried by window.matchMedia. The other one is

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 defines three flushing functions that flush different parts of the
WR pipeline. Using all three guarantees that everything sent to WR will
have been flushed. This is what we need to do in SyncWithCompositor to
ensure that it meets the API contract.
In addition, this patch updates the existing FlushRendering function to
use the new functions (no functional changes intended here).

Instead of crashing the process inside Transition on a bad state transition,
propagate an error up the stack (and crash higher up).

ByteBuf is a new IPDL built in type, so I wrote a very basic test for
it, based on shmem.ipdl. It was added in bug 1379680.

Bug 1443954 added some new syntax to using, but I noticed that there
was not very much existing test coverage, so I wrote a new test that
covers all of the possible cases.

The IPDL parser now expects a valid message-metadata to be passed in,
even though we don't need it for parser tests. Fix this by creating
and specifying a blank one. This fixes a regression from bug 1348591.

The ipc/ipdl/test/cxx/ subdirectory is only built when MOZ_IPDL_TESTS
is set, because it needs special code to be built into the
binary. ipdl/ should always be built, because it does not need special
support. This gating is already done in the ipc/ipdl/test/ directory,
so it shouldn't be done in ipc/ipdl/, because this stops us from
building it in a regular build.

We can move this information into ProtocolState and save having two
virtual functions for every protocol. Moving some bits out of the
codegen'd IPC code is a nice bonus, though we keep the strange setup
where toplevel protocols have two mChannel member variables.
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.
lower.py generates repetitious:
SetManager(...);
Register(...); // Or RegisterID.
SetIPCChannel(...);
calls, which are moderately sized, given that the above call sequence
requires virtual calls in several places. Instead of codegenning this
sequence, let's consolidate the sequence into IProtocol and change the
code generator to call into the consolidated function instead.
This patch was reviewed in parts, however the intermediate states would not build:
Bug 1443954 - Part 3A: Strip pointers from the argument to WriteParam and WriteIPDLParam before selecting the ParamTraits impl, r=froydnj
Bug 1443954 - Part 3B: Move nsIAlertNotification serialization to the refcounted system, r=bz
Bug 1443954 - Part 3C: Move geolocation serialization to the refcounted system, r=bz
Bug 1443954 - Part 3D: Move nsIInputStream serialization to the refcounted system, r=baku
Bug 1443954 - Part 3E: Move BlobImpl serialization to the refcounted system, r=baku
Bug 1443954 - Part 3F: Correctly implement ParamTraits for actors after the ParamTraits changes, r=froydnj
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.

This is important as these includes are often used to define ParamTraits
implementations which are needed to serialize struct members and
parameters. The place where the code which uses these implementations
will be moving from the protocol where they are used to the file where
the structs are defined, which means we need to includes these files
there.

The FunctionBroker actors allow the NPAPI process (child) to run methods on the main process (parent). Both the parent and the child run dedicated threads for this task -- this is a top-level protocol.

pure or override implies virtual. static is mutually exclusive with virtual (and pure and override). Combining these types into a "method specifier" enum simplifies the code and prevents bogus states like virtual=0 and pure=1.
