Fairly straightforward, just a blanket removal. Haven't heard
anything on dev-platform or fx-data-dev regarding this removal,
so I think it's likely safe to remove on Nightly, and we can
revert if anyone makes a fuss.
As part of removing the HangMonitor, I renamed a few things and
reorganized the namespaces to not depend on a HangMonitor
namespace. Hopefully this doesn't produce too much noise in the
diff, it just seemed appropriate to move everything around
rather than keep dangling vestiges of the old system.

This is causing LSan leaks which don't have an easy fix, and we're
already not running it in debug builds, so it can't hurt too much.

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 also changes many references to the 'pseudo stack' to refer to the 'label
stack' instead. The label stack is one of the two stacks that are managed by
the profiling stack, the other stack being the JS interpreter stack.

The name Cpp was confusing, because C++ functions are in the native stack, not
in the pseudo stack. The pseudo stack only contains frames for manually
instrumented code that uses AutoProfilerLabel, and JS frames.

This also removes any redundant Ci.nsISupports elements in the interface
lists.
This was done using the following script:

If we enter a hang through the normal timed loop of RunMonitorThread, and then
call NotifyWait, it will result in a hang with an indefinite duration being
reported once NotifyActivity is called again.

When the BHR wants to report a tardy thread, it hands off the work of
getting a stacktrace to a helper thread. The helper threads used are in the
Stream Transport Service threadpool, which has a default limit of 25
threads.
This has a bad effect when we are in a severely compute-resource constrained
situation. Then, many threads will be late, and up to 25 STS worker threads
will be employed to do unwinding, a potentially expensive operation. This
further restricts the compute resources available to progress the rest of
the system.
Another effect is that the unwinder work will compete against the "real" STS
work for the 25 workers, potentially further slowing forward progress.
This patch replaces the use of the STS thread pool with a single nsThread
dedicated to unwinding/reporting hangs.
This patch was autogenerated by my decomponents.py
It covers almost every file with the extension js, jsm, html, py,
xhtml, or xul.
It removes blank lines after removed lines, when the removed lines are
preceded by either blank lines or the start of a new block. The "start
of a new block" is defined fairly hackily: either the line starts with
//, ends with */, ends with {, <
