I don't think ConditionVariable has ever been, in theory, immune to
spurious wakeups, and this caller wasn't dealing with it correctly.

It is replaced by a standard-conforming cast to (void) which is
understood the same by the compiler.
In some cases this could be replaced by `[[maybe_unused]]` but for
expression whose value is ignored, this requires storing to a temporary
variable first, so not going that way.
One notable change is that marking an object of type already_AddRefed as
unused used to implicitly leak memory. This is now made explicit.
Most of the heavy lifting was done through:
$ git grep -l '\<Unused\> <<' | xargs sed -i -e 's/Unused << /(void)/g'
$ git grep -l mozilla/Unused.h | xargs sed -i -e '/mozilla\/Unused.h/ d'

Most changes are automated. Relevant bit is dom/.clang-format. I had to
manually disable clang-format in a few places where importing external
files and so on that aren't self-contained, and fix a couple includes /
forward declarations.

This combines the multiple fields or variants which were previously used to
track sided types like protocol types into a single field wrapped with a
SideVariant.
This will be used in the next part to avoid the need for default constructors
for actor types allowing the proper types to be used.

This is semantically similar to the existing available() method, however will
not block, and doesn't need to do the work to actually determine the number of
available bytes.
As part of this patch, I also fixed one available() implementation which was
incorrectly throwing NS_BASE_STREAM_WOULD_BLOCK.

In the testcase, clone() will trigger the first AsyncOpenStreamOnOwningThread() call and shortly after that read() will trigger the second one. For both calls mSnappyStream isn't set yet, and the first one finishes first and get the stream.
When the second run of AsyncOpenStreamOnOwningThread starts, the first run already got the stream and thus OpenStream fails. Then it thinks there should be no stream since it failed, but there is, so assertion fails at line 481.

As serializing IPCStream no longer requires a manager or FileDescriptor array,
the arguments are no longer necessary, and can be removed. The AutoIPCStream
helper can also be removed, as managed actors are no longer used for
serialization, so a delayed start callback is not necessary.
The delayed start parameter is also removed from nsIIPCSerializableInputStream
instances, but is still present as `aAllowLazy` on the toplevel serialization
methods.

This gives us various positive benefits, such as using a shared memory ring
buffer for faster communication, not having data streaming being bound to the
thread which transferred the nsIInputStream (which is often the main thread),
and the ability for some backpressure to be applied to data streaming.
After this change, the "delayed start" parameter for IPCStream serialization is
less relevant, as backpressure will serve a similar purpose. It will still be
used to determine whether or not to use RemoteLazyInputStream when serializing
from the parent process.

Before P1, GetCurrentThreadSerialEventTarget would have always returned the same data as NS_GetCurrentThread, making the comment incorrect Now it will properly return the running TaskQueue if any.
This change of name more clearly exposes what they are doing, as we aren't always dealing with threads directly; but a nsISerialEventTarget
