The new names make it clearer that these actions apply to just one thread.
- profiler_sleep_start() --> profiler_thread_sleep()
- profiler_sleep_end() --> profiler_thread_wake()
- profiler_is_sleeping() --> profiler_thread_is_sleeping()
- GeckoProfilerSleepRAII --> GeckoProfilerThreadSleepRAII
- GeckoProfilerWakeRAII --> GeckoProfilerThreadWakeRAII
It's fairly straightforward, and measures the important parts of:
- Sampler, PseudoStack, ProfileBuffer, ThreadInfo.
- LUL, PriMap, SecMap
Coverage isn't perfect, but it gets the major things I found via DMD on Linux.

Handling potential nsDeque size changes means a bit of extra work.
But if the nsDeque is const, we can assume that it shouldn't get modified, so
we can provide a more optimized iterator that doesn't need to handle size
changes.
Optimizing a range-for loop in which the deque is not modified, can be done
by writing: `for (void* item : const_cast<const nsDeque&>(deque)) {...}`

Note that iterators stay at the same index if the deque size changes
(including end-iterators staying at the end).
This means that after front operations, iterators will effectively point at
different elements! (Possibly skipping or re-visiting some.)
But this is consistent with ForEach and hand-crafted index-based for loops.

We can make some assumptions now that the Input method is only called once and never again while a decode is pending.

Removing the exported symbols is straightforward enough.
The only wrinkle is that PeerConnectionCtx.cpp gets compiled with and
without MOZILLA_INTERNAL_API. When compiling without
MOZILLA_INTERNAL_API, mozilla::services::Get*Service was redirected to
the _external_* symbol variants. But as the _external_* symbols no
longer exist, PeerConnectionCtx.cpp's code no longer worked.
Fortunately, PeerConnectionCtx.cpp already contains a few #ifdef
MOZILLA_INTERNAL_API blocks to handle internal/external compilation;
fixing this newest issue was just a matter of extending existing blocks
and adding new ones. The key observation is that we never added any
observers when compiling without MOZILLA_INTERNAL_API, so we can #ifdef
out the removals of observers, as those would have no effect, and simply
skip getting the observer service for the observer additions if we're
compiling without MOZILLA_INTERNAL_API.
It's now possible to write:
for (void* item : deque) { ... }
