This version of the patch hopefully causes fewer performance regressions.
It might be good to apply this and catch some more assertions.

Now that nsArray uses nsCOMArray under the hood, we don't have to do weird
ForwardEnumeration hacks to start IndexOf at a non-zero index.

The users of WriteSegmentFun and ReadSegmentFun read the final out parameter
whether or not the function returns an error. We should make sure to fill it
in with a sane value.

There's no good reason why these can't be code constants.
Especially given that, due to a bug, changes to the
"idle_queue.{min,long}_period" constants were not being passed onto the C++
code!
Here's why: those two prefs were specified as integers in all.js. But we used
AddFloatVarCache() to set up the reading of those prefs. libpref fakes floats
by storing them as strings and then converting them to floats when they are
read.
Which means that AddFloatVarCache() used to fail to get the value from all.js
-- because there's a type mismatch, int vs. string -- and instead use the
fallback default. That value is the same as the one in all.js, which is lucky.
But if someone changed the value in about:config to 100 (an integer), a similar
failure would have occured and the value used by the C++ code wouldn't be
updated!
Also note that idle_queue.max_timer_thread_bound did not have a value in
all.js.
What a mess!

There's no good reason why these should't just be constants. The patch also
appends "MiB" to some of the C++ values to make their meaning clearer.
This patch fixes one outright bug, and one inconsistency.
The bug is due to a prefname mismatch:
- ContentPrefs.cpp and AvailableMemoryTracker.cpp use
"memory.low_virtual_mem_threshold_mb".
- all.js uses "memory.low_virtual_memory_threshold_mb".
Which means that "memory.low_virtual_memory_threshold_mb" showed up in
about:config, but if you changed it nothing would happen because the callback
listened for changes to to "memory.low_virtual_mem_threshold_mb"!
Now for the inconsistency. The above means we actually use a value of 256 for
the virtual memory threshold, even though all.js says 128. But we *do* use a
value of 128 for the commit space threshold, because that's what all.js says
and that prefname is used correctly everywhere. The patch changes the commit
space threshold to 256 for consistency with the virtual memory threshold.
What a mess!

This was originally added for b2g, where the pref had a different value.

This removes dead code using headlessClient and lastRunCrashID in crash
reporting. headlessClient is unconditional now. nsIXULRuntime.lastRunCrashID
is not used anymore so remove code for implementing it.

MOZ_CRASH_UNSAFE_PRINTF causes data collection because crash strings are annotated to crash-stats and are publicly visible. Firefox data stewards must do data review on usages of this macro. However, all the crash strings this patch collects with MOZ_CRASH_UNSAFE_PRINTF are already collected with NS_RUNTIMEABORT.
