Change the Mac GMP process launch to include sandboxing params on the command line to allow the sandbox to be started earlier during GMP process launch. Content, extension, and RDD processes have already been changed to start the sandbox earlier.
Update GMPProcessParent to override GeckoChildProcessHost methods used to construct sandboxing parameters. Pass the plugin path as a sandbox parameter so that the sandbox rules can whitelist the plugin directory which is now read after the sandbox is enabled in the plugin process. On development builds, pass "testingReadPath" params so directories needed during automated tests can be whitelisted.
Update Mac sandboxing code to detect GMP sandbox params on the command line and enable the sandbox with additional arguments needed for early sandbox start.
Allow reverting to the old implementation by setting security.sandbox.gmp.mac.earlyinit to false.

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.

This patch includes multiple changes cleaning up various aspects of the crash
reporter client and exception handler:
* Some Unix-specific code was moved out from the base crashreporter client
code and into the appropriate platform implementation
* Functions used to open files in the crashreporter client now accept C++
`std::ios` flags instead of unreadable booleans
* Useless character conversion routines were removed from the
minidump-analyzer
* Crash annotations are not serialized into a huge string anymore every time
they change. They are all written out individually during an exception.
* `WriteEscapedMozCrashReason()` uses the exception-safe `my_strlen()` instead
of plain `strlen()`
* The Windows-specific DLL-blocklist shutdown was removed from the Linux &
macOS Breakpad callbacks
* The `CrashReporterHost`, `CrashReporterClient` and
`CrashReporterMetadataShmem` classes now take `nsACString` references
instead of `nsCString` ones since they never modify their contents

The current situation is suboptimal, where we have the same goop

thanks to the linker for files that would have been forbidden, except
when the linker doesn't do its job, which apparently happen on

This change only really covers C++ code using operator new/delete, and

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.

Upon a content process crash or hang crash annotations were incrementally
written into the .extra file starting with the exception handler callback and
then in a number of different places before the file was ready for submission.
This had a number of downsides: since the annotations were directly added to
the file it was impossible to tell which ones were already written at a
certain point in time, additionally some were written twice or even thrice.
The code doing the writing would also behave differently depending on the
contents of the file, the parameters passed to it and the contents of global
variables.
This change overhauls the whole process by keeping the annotations into a
temporary per-crash annotation table which is filled with all the required
annotations before being written out in a single pass when they are ready.
The annotations are gathered from the main process annotation table, the
per-process one (held by the CrashReporterHost) and exception-time specific
ones.
The resulting annotations are slightly different than before the patch: first
of all there are no more duplicate entries in the .extra file and secondly all
content/plugin process hangs annotations are properly filtered, before
annotations that were main process-only would leak into them.

This patch takes care of a bunch of issues and does some cleanup:
* We rename mscom::MainThreadRuntime to mscom::ProcessRuntime, as the latter
is a more accurate name going forward.
* We make ProcessRuntime aware of the Win32k Lockdown process mitigation
policy. When Win32k is disabled, we perform process-wide COM initialization
in the multi-threaded apartment (since we cannot create an STA window).
* We refactor the mscom apartment region stuff to enable the Win32k lockdown
pieces in ProcessRuntime.
* We move some Gecko-specific stuff into MOZILLA_INTERNAL_API guards so that
ProcessRuntime is usable outside of xul.dll (I will be needing it for the
launcher process).
* Another thing that might happen with the launcher process is that, under
error conditions in the launcher, we create a ProcessRuntime object on a
background thread for the purposes of telemetry logging, but we also allow
the main thread to proceed to start as the browser. This could result in a
scenario where the main thread, as the browser process, is attempting to
instantiate its ProcessRuntime and ends up racing with the launcher process's
telemetry thread which has its own ProcessRuntime. To account for this
situation, we add mutual exclusion to the process-wide initialization code.
We host this part inside mozglue since that state is shared between both
firefox.exe and xul.dll.
* We clean up ProcessRuntime::InitializeSecurity by using Vector to set up
the EXPLICIT_ACCESS entries.
* We remove mscom::MainThreadClientInfo and replace it with a direct call to
CoGetCallerTID
* We revise all references to this class to use the new name.

* New topLevel loads get the nsILoadInfo.openerPolicy of the current top level document
* Parsing the Cross-Opener-Origin-Policy of a channel will update mLoadInfo.openerPolicy and this value will get propagated to the child process.
* SessionStore now checks nsIHttpChannel.hasCrossOriginOpenerPolicyMismatch (preffed off) and performs a process switch if needed

The one exception is refcounted types, because std::move(RefPtr<T>) does not
coerce to T*, which is what the current IPC methods accept.
This does not rewrite all Recv/Answer methods to take advantage of move
semantics.

Shmem sizes serialized in an ipc::ShmemCreated message should be sent as an
uint32_t rather than a size_t, as size_t is defined as different sizes in 64
and 32 bit builds. If the size isn't consistent, we won't be able to reliably
send this message between cross architecture processes.
Also, Shmem's have a limit of 32bit for their size anyway:
https://searchfox.org/mozilla-central/rev/e00ea598e52bbb35f8c45abf9c2eade17962bb5e/ipc/glue/Shmem.cpp#127
So this patch should not affect allocations of shmems.
