In the following patch we are going to change the signature of
ShouldSanitizePreference to take a Pref object. Pref is only
known to the Preferences compilation unit; so to keep this member
(whose signature will change) we would need to expose the Pref
class. However it will only be a forward declaration, one could
not construct a Pref object in e.g. the gtest.
It is simpler to just remove the member entirely and call
ShouldSanitizePreference unconditionally - the member was only
used for the gtest, and while the gtest will be less robust
because of this change, it will still do some testing.

With this new approach, Shmem instances will now have their handles
transferred inline within messages as attachments, rather than being
associated with their actors and sent in separate messages.
This has a few advantages:
* The implementation is much simpler
* Releasing all references to a Shmem will automatically destroy it by
RAII, rather than leaking the shared memory region until the toplevel
actor is destroyed, removing the need for types like RaiiShmem.
* This allows re-transmitting Shmem instances to another process, as we
don't close the shared memory region handle upon receiving it.
But also has a disadvantage that because we keep alive the shared memory
region's handle until the shmem is destroyed, so that it can be
re-transmitted, we may end up using more FDs or HANDLEs while running.
This patch intentionally doesn't change or simplify callsites, removing
APIs like RaiiShmem, in order to make it easier to revert if this causes
issues on platforms like Linux due to FD exhaustion. If we don't run
into increased resource exhaustion problems, we can make these changes
in a follow-up.

The Python IPDL frontend checks for includes before checking if the
entire file is syntactically valid. However, my Rust IPDL front end
does it later, so it ends up failing in a syntax error before
noticing the invalid include. I think the basic issue is that this
file wasn't updated when async was made mandatory, because it didn't
affect the results. Let's just fix the file so it only tests one
thing.
Differential Revision: https://phabricator.services.mozilla.com/D141445
Before this change, the collection of typedefs to include in IPDL
protocols was being performed in the _DecorateWithCXXStuff pass of
lower.py. This pass iterates over all included headers, including
recursively, so will also visit headers included by headers you import.
The recursive behaviour caused issues because importing and
forward-declaring imported types is non-recursive, looking at exported
types only one layer deep. This could lead to typedefs being generated
in IPDL protocols referencing types which could never be named by the
IPDL code, and which had no definition in c++, leading to build errors.
This patch changes the logic to instead happen during the
_GenerateProtocolActorCode pass of lower.py, which is also where
required forward declarations and imports are handled, allowing us to
keep the set of typedefs generated more tightly in sync with the actual
set of types available to the actor.
This required some changes in client code which was relying on
incorrectly generated typedefs, however these types have now been fixed.

This patch introduces a new system for building IPDL unit tests, which is
roughly inspired by the old cxx unit test design, however designed to work with
gtest. It re-uses the existing IPDLUnitTest process type, using static
constructors only present in xul-gtest to register child actor constructors and
ProcessChild implementations to avoid bloating xul.
The IPDLUnitTest actor is used as a backchannel to communicate test failures
from the child process back to the parent process, and manage the test's async
lifecycle more reliably.
The IPDLUnitTest process also needed to have various properties about how it was
initialized adjusted:
* The IPDLUnitTest process should now always load xul-gtest when running
gtests, by using the "Self" process type and adding a DYLD_LIBRARY_PATH override
on macOS where the "Self" process type cannot be used.
* The IPDLUnitTest process now initializes minimal XPCOM, and runs a
frankeneventloop to allow it to use XPCOM event loop structures such as
SpinEventLoopUntil in tests.
* Support for creating IPDLUnitTest processes on Android was added, as these
tests had never run on android before.

These attributes replace the previous direct_call.py table which
specified how to locate the concrete implementation of a protocol and
whether it should use a virtual implementation or not.
They work by specifying the concrete type for an actor, and disabling
the automatic inclusion of the implementation's header file, which can
be included explicitly with an `include "";` statement. This allows
customizing both the name and include path of the concrete
implementation of an interface.

Previously, the screenOrientation.lock API was for Fennec and not supported for Fenix and multi-process use. The overall idea is to now allow apps to use the API through a delegate and make asynchronous calls to LockDeviceOrientation. This required replacing the existing code that returned a default false bool to calls that perform the requested orientation change and instead return a promise that contained either an allow or deny value.
Returning a promise instead of a bool involved changing the API calls from the C++ side to Java. The new general control flow of screenOrientation lock follows: an app calls C++ ScreenOrientation.lock() which eventually dispatches LockOrientationTask to resolve the pending orientation promise. Hal.cpp sends an IPC call to the content process and RecvLockScreenOrientation retrieves the current instance of geckoRuntime and calls the java side LockScreenOrientation. Apps must create a delegate and override onOrientationLock to set the requested orientation. In geckoview's testing, this is done with the android API setRequestedOrientation. Once a device orientation change has been triggered, native OnOrientationChange calls to NotifyScreenConfigurationChange, which notifies all observers and dispatches a change event to resolve the pending orientation promise.
Testing:
I used a demo on the GeckoView Example (https://usefulangle.com/demos/105/screen.html) to test locking to landscape orientation. This required a change to the GVE to show the app from recreating the whole thing on orientation change. In the example AndroidManifest xml file, `orientation` prevents restart when orientation changes.
The Junit/Kotlin tests were to verify that the expected orientation delegate was called with the expected new orientation value, in an orientation change, if the new orientation was the same as the current, and if the pre-lock conditions such as being fullscreen were not met.
A static preference `dom.screenorientation.allow-lock` was added to the dom group, since it affects the ui dom) and is currently turned off. C++ can access it through its mirrored variable dom_screenorientation_allow_lock (same name but with underscores). The junit tests turn the preference on and test the lock feature.

In bug 1595994 we attempted to streamline the ability to determine which decoder was available regardless of the process they would be running in. This was subsequently done via the PDMFactory.
As there are several JS API that can query which codec are supported, it requires a synchronous mechanism.
This allowed to make a determination during the PlatformDecoderModule::Supports call, depending on which process it was going to be called frome.
Having a synchronous IPC call to the RemoteDecoderManagerParent has too many caveats to be workable.
So what we do instead is first determine at launch if the required external framework are available and pass this information to each content process.
When checking if a decoder is available, we make a best guess at determining if the PDM would support such codec, without actually loading such framework when running in the content process.
Supports can no longer make a decision based on the process currently running and as such PDM::CreateAudio/VideoDecoder using an optional system framework now need to further check the validity of the CreateDecoderParam argument.

To produce this patch I did all of the following:
1. Make changes to tools/lint/black.yml to remove include: stanza and update list of source extensions.
2. Run ./mach lint --linter black --fix
3. Make some ad-hoc manual updates to python/mozbuild/mozbuild/test/configure/test_configure.py -- it has some hard-coded line numbers that the reformat breaks.
4. Add a set of exclusions to black.yml. These will be deleted in a follow-up bug (1672023).

And we remove unnecessary checks, BackgroundParent only run in the parent process and if e10s is on. Also RecvLauchRDDProcess will only ever be called if the rdd pref is on already.
By streamlining the call we also reduce the number of sync dispatch to 1.

Add a synchronous Supports message to the IPDL PRemoteDecoderManager protocol so
decoder modules can query for playback support in the actual process that will
attempt to do the decoding.

The `clobber` targets are superseded by `mach clobber`, so we don't need them for any reason. The `clean` target is meant to get you to a post-`configure` state, but it doesn't really work, and if it's necessary for you to be in that state for some reason you can just clobber and re-`configure`, so it doesn't seem worth it to get it working again. Instead, delete all of them. Also delete `everything` which is not useful when `clobber` doesn't exist.

This patch does:
- Use LSWriteOptimizer
- Remove SessionStorageService since it's unused.
- Move IPC from PContent to PBackground
(by SessionStorageManager{Child, Parent} and SessionStorageCache{Child, Parent}).
- Extract SessionStorageManagerBase and add PBackgroundSessionStorageManager.
- Expose a getter function to get a BackgroundParentManager for top context id
on the parent.
IPC
- Before this patch:
- Copy from parent while loading a document.
- Mark cache entry on the parent process as loaded by the child id.
- Update change on checkpoint.
- Unmark cache entry on the parent process as unloaded for the child id while
the parent actor is destorying.
- After this patch:
- Sync IPC load in the first SessionStorage operation.
- Update change on checkpoint
`BackgroundSessionStorageManager`'s lifecycle on the parent process.
- Create by `SessionStorageManagerParent` and register to the `sManagers`.
- Hold by `SessionStorageManagerParent` and `sManagers`.
- Remove from the `sManagers` while the corresponding `BrowsingContext` is
destructed (on the parent process).

There are at least 8 different methods for getting a range from an offset:
1. left word
2. right word
3. line
4. left line
5. right line
6. sentence
7. paragraph
8. range with same style.
Having a single wrapper and IPDL method for all of those with an enum would remove
a lot of redundancies.

We use C++14's generic lambdas and its auto&& type in the generated code, in combination with a typed local variable to ensure the argument type is enforced.
The object is moved as necessary, no copies will occur.
The code generated will now be:
[this, self__, id__, seqno__](auto&& aParam) {
if ((!(self__))) {
NS_WARNING("Not resolving response because actor is dead.");
return;
}
bool resolve__ = true;
InitResultIPDL result = std::forward<decltype(aParam)>(aParam);
IPC::Message* reply__ = PRemoteDecoder::Reply_Decode(id__);
WriteIPDLParam(reply__, self__, resolve__);
// Sentinel = 'resolve__'
(reply__)->WriteSentinel(322044863);
WriteIPDLParam(reply__, self__, std::move(result));
// Sentinel = 'result'
(reply__)->WriteSentinel(153223840);
(reply__)->set_seqno(seqno__);
}
For multiple arguments return, creation of Tuple via Tie is also moved, though currently Tie method doesn't support move semantics.

Doing this helps lower the chances of accidentally trying to send an
uninitialized primitive value, like a raw pointer or integer, over IPC due to a
sync method or IPDLParamTraits::Read implementation failing to initialize the
outparameter.

We need a sync IPC call for this because otherwise the number of smaller sync messages we would need to call would be variable.

This changes the duplicate checking/caching implemented by |parsed| to be
based on the name of the protocol etc. we're loading, not the file name.
This lets us detect when a protocol is being defined in two different
files.
This can happen if one file is included earlier in the resolve path than
a file explicitly specified on the command line. Any includes will resolve
to the former, and then we'll attempt to parse the latter. Before this
patch, this would result in weird errors, because there would be multiple
protocol types with the same name.

This moves the IPC mechanism from PCompositorBridge to PLayerTransaction/
PWebRenderBridge, so that it can be used by content processes like the other
test APIs. It still only produces actual data for the layers backend; for
WR it will just return empty datasets.

It could go into its own test suite, but it 1) depends on `mozbuild` code, so the `mozbuild` suite as well as this new suite would be running on any push that touches `mozbuild` code anyway, and 2) this is code that runs during the build, so it's not out of place.

Having two classes in the inheritance chain inherit from SupportsWeakPtr
now won't compile, but you can use WeakPtr<Derived> when any base class
inherits from SupportsWeakPtr.

* Use clearer pref names.
* Default (and only support) IPDL dispatching.
* Make DispatchCommands async-only.
* Sync ipdl command per sync webgl entrypoint.
* Eat the boilerplate cost, since there's not too many.
* Run SerializedSize off same path as Serialize.
* All shmem uploads go through normal DispatchCommands.
* Defer pruning of dead code for now so we can iterate quickly.
* Use Read/Write(begin,end) instead of (begin,size).
* This would have prevented a bug where we read/wrote N*sizeof(T)*sizeof(T).

The speedup here is not great because the Python/IPDL parser overhead is
very high, but this cuts ~10 seconds off a `-j12` build (~15s -> 4s) on
my machine.

I don't think all this complexity is worth it for having a
marginally-more-realistic testing story. Using the pref just works and we should
do that, I think.

This method always copies, and is redundant with the other getter methods on
IPDL unions. As there is only one caller, it can be removed to simplify the
code, and remove a source of complexity.
