This patch does not change any of the *internals* of process management in
`GeckoProcessManager`, however it upgrades the interface in preparation for
such changes.
* We add a java equivalent to Gecko's `GeckoProcessType` enumeration;
* We add the `GeckoProcessType.Selector` class which will be used for
identifying running content processes;
* We update `ContentParent::MarkAsDead` to use `GeckoProcessType.Selector` for
indicating which process should be marked.

It's no longer safe to try closing client_pipe_ when the I/O thread is
woken up with data from the child process, because that can race with the
launch thread doing its own close, and it's also unnecessary because of
that other close. See also bug 1607153 comment #2.

Splits WebGLContext into ClientWebGLContext and HostWebGLContext. The Client enables the JS-control of a WebGL context in a content procecss while the Host executes the WebGL graphics operations (via a WebGLContext that maintains much of the existing code) in the compositor process. At this point, the cross-process behavior is disabled -- this series of patches is an incremental step toward that final goal.

When a content or plug-in process crashes too early we haven't initialized the
CrashReporterHost for that process. This will cause the crash to be orphaned,
i.e. to miss most of its crash annotations. We added code to finalize those
crashes in bug 1282776 so that we wouldn't miss them entirely. This ensured
that crash reports would have both their .dmp and .extra files but the patch
failed to modify the code that notified various listeners about the crash
report's presence.
This changes always send the crash ID alongside the crash notifications, even
for orphaned crashes, so that listeners such as the content crash handler or
the test harnesses can always find the minidump and .extra file. Additionally
orphaned crashes are recorded in the CrashManager and in telemetry just like
normal crashes.
This also re-enables dom/ipc/tests/process_error.xul which failed frequently
because of this bug.

Previously, we created TextureD3D11 objects in the content process to back surfaces created for the plugin process. Those objects were then composited by the async ImageBridge. In order to remove Win32 kernel operations from content (including DX/GDI operations), this patch bounces the requests from content to the compositor process. The compositor process maintains 2 textures to be used for all plugin composition -- one for the plugin process and one for display. The plugin process can freely write to its texture and request composition when it is done, which triggers a blit to the display texture. This mirrors pre-existing behavior.

These operations report whether certain async plugin drawing modes are supported on the host architecture. They use kernel graphics operations to decide this so they need to be removed from the content process for sandboxing.

While the need for adding `mozilla::Vector` is self-evident, we also need
`std::vector` so that we can send some pre-existing telemetry data structures
that use it.
The new implementations are basically modified from the `nsTArray`
specializations. Note that the `mozilla::Vector` specialization does support
any type of allocator, so we still check for OOM failures in that case.
This patch also removes the specialization for `std::vector` that lives in
WebRTC in favour of the centralized implementation.

There are two issues here:
1. These error messages occur even during normal channel shutdown,
because that's tracked in the mozilla::ipc::MessageChannel layer,
which the ipc/chromium code can't access.
2. If we get this kind of error when the channel wasn't intentionally
closed, it almost certainly means that the other process crashed. In
that case, having error messages from a different process and a likely
unrelated subsystem just leads to confusion and misfiled bugs.
(Also complicating things: on Unix a closed channel often, but not
always, results in an end-of-file indication, which already isn't
logged; on Windows it's always a broken pipe error, which causes a much
larger amount of log spam.)
Bonus fix: the error that contains a fd number is clarified to avoid
having it mistaken for an error code.
