Bug 919838 - Specialize ToInt32 for Float32. r=sstangl, a=lsblakk
Bug 925663 - Establish HSP connection if and only if HFP service record couldn't be found. r=gyeh, a=koi+
Bug 891904 - Un-schedule full spell check when checker is disabled. r=ehsan, a=akeybl
Bug 923173 - Use NS_WARNING for unexpected name to avoid crashing. r=ehsan, a=koi+
Bug 923106 - Recompute frequency dependent parameters when OscillatorType changes. r=padenot, a=akeybl

mSquare, mTriangle, and mSaw are not initialized in the OscillatorNodeEngine
constructor, just like they are not initialized when switching to
OscillatorType::Sine.  These parameters are initialized if and when switching
to the OscillatorTypes that use them.

mFinalFrequency, mNumberOfHarmonics, mSignalPeriod, mAmplitudeAtZero,
mPhaseIncrement, mPhaseWrap are not initialized in the OscillatorNodeEngine
constructor, just like they are not initialized immediately on switching
OscillatorType.  These parameters are initialized in
UpdateParametersIfNeeded(), conditional on mRecomputeParameters.
