sutagent is no longer built or usedr; devicemanagerSUT is completely
unused. After this change, devicemanagerADB is the only implementation of
devicemanager, and the --dmTrans and similar options have been removed
from test harnesses and mach commands.
Sicne some tests doesn't work with --with-intl-api=no, we should skip it on Android

Now that we join on the thread exiting, we no longer need to have the thread
explicitly tell us it's shutting down.

Currently, JS sampling has major problems.
- JS sampling is enabled for all JS threads from the thread that runs
locked_profiler_start() -- currently only the main thread -- but the JS
engine can't handle enabling from off-thread, and asserts. This makes
profiling workers impossible in a debug build.
- No JS thread will be JS sampled unless enableJSSampling() is called, but that
only happens in locked_profiler_start(). That means any worker threads
created while the profiler is active won't be JS sampled.
- Only the thread that runs locked_profiler_stop() -- currently only the main
thread -- ever calls disableJSSampling(). This means that worker threads that
start being JS sampled never stop being JS sampled.
This patch fixes these three problems in the following ways.
- locked_profiler_start() now sets a flag in PseudoStack that indicates
JS sampling is desired, but doesn't directly enable it. Instead, the JS
thread polls that flag and enables JS sampling itself when it sees the flag
is set. The polling is done by the interrupt callback. There was already a
flag of this sort (mJSSampling) but the new one is better.
This required adding a call to profiler_js_operation_callback() to the
InterruptCallback() in XPCJSContext.cpp. (In comparison, the
InterruptCallback() in dom/workers/RuntimeService.cpp already had such a
call.)
- RegisterCurrentThread() now requests JS sampling of a JS thread when the
profiler is active, the thread is being profiled, and JS sampling is enabled.
- locked_profiler_stop() now calls stopJSSampling() on all live threads.
The patch makes the following smaller changes as well.
- Renames profiler_js_operation_callback() as profiler_js_interrupt_callback(),
because "interrupt callback" is the standard name (viz.
JS_AddInterruptCallback()).
- Calls js::RegisterContextProfilingEventMarker() with nullptr when stopping
JS sampling, so that ProfilerJSEventMarker won't fire unnecessarily.
- Some minor formatting changes.

PseudoContext::sampleContext() is always called immediately after
profiler_get_pseudo_stack(). This patch introduces profiler_set_js_context()
and profiler_clear_js_context(), which replace the profiler_get_pseudo_stack()
+ sampleContext() pairs. This takes us a step closer to not having to export
PseudoStack outside the profiler.
