Bug 1342306 (part 1) - Introduce SamplerThread class in platform-linux-android.cpp. r=jseward. This makes it more like platform-{macos,win32}.cpp, and will make it easier to introduce locking around all the globals in platform.cpp. The following things were moved into the new class. - Types: - SigHandlerCoordinator - Functions: - SigProfHandler() - SigprofSender() as Run() - Variables: - gOldSigprofHandler as mOldSigprofHandler - gSigprofSenderThread as mThread - gIntervalMicro as mIntervalMicro - gSigHandlerCoordinator as sSigHandlerCoordinator sInstance is the singleton instance. PlatformStart() and PlatformStop() now just delegate to StartSampler/StopSampler. The patch also does the following tidy-ups. Linux: - gWasPaused is now cleared in the parent and child processes after forking. - LUL: inlined and removed gLUL_initialization_routine(). - LUL: now only calling EnabledUnwinding() and doing the unit tests on the first call to profiler_start(), instead of all of them. Mac: - Removed a useless call to pthread_self() -- mThread is already set by the earlier call to pthread_create(). - Removed some low-value checking involving kNoThread. Mac + Win: - Renamed SamplerThread::mInstance as sInstance, because it's static. - Merged SamplerThread::Start() with the constructor. - Tweaked how mInterval/mIntervalMicro is initialized, so it can become const. All platforms: - Converted NULL to nullptr throughout. - A few other very minor clean-ups, e.g. formatting.
